Iridium candles NGK selection by car. How to perform selection of spark plugs on a car brand

22.11.2019

Selection of spark plugs - difficult process, the subtleties of which you need to know by car owners. Problems in these details can lead to car malfunctions. Many motorists are trying to dry or clean iridium and other products, but in case of their failure, only the timely substitution of the part can help. To choose a suitable product, you need to take into account some nuances.

When choosing new components, attention should be paid to the size, material manufacturing material, condition of wires, a calil number, resource, features of operation and value of a particular product.

Some of the best products rightfully considers products of DENSO and NGK brands, which include iridium, yttrium and platinum products. In addition, these manufacturers produce incandescent candles and high voltage wires.

The main parameters that need to be considered before choosing such a product - geometric dimensions and a calil number of spark plugs. It is worth considering each of these parameters in more detail.

Candle size

When an inappropriate amount of this product may have a number of problems. For example, an insufficient value of the value is not screwed into the engine slot, so the electrodes will be located too far from the combustion chamber. If the dimensions exceed the permissible, the probability of the piston strike on the electrodes appears. Therefore, it is necessary to correctly select the dimensions of the part, which must be listed in the instructions for the vehicle. NGK and DENSO products are available in a wide range of dimensional variations. Under these brands, incandescent candles and high voltage wires are made.

Kalil number

This parameter reflects the temperature range of the part. The more this indicator, the more colder products, which allows it to exploit it in a high temperature medium.

The lower the value of the calil number, the "hot" part, it may overheat in the conditions that can be significantly reduced to its use, which can significantly reduce its life.

In the instructions for the car it is indicated which values \u200b\u200bof this parameter are permissible. The table of analogue of spark plugs taking into account these parameters includes many positions to facilitate the choice, including NGK and DENSO. These brands also include incandescent candles and high voltage wires.

Types of structures

The classification of spark plugs assumes the presence of several types of products. In the car typically use spark details of the classic design. They are characterized by the presence of a ceramic hull and a lower metal part with a thread. The simplicity of design determines the low price even on new products. Such a product can improve the use of the engine by reducing power consumption. The minus is a small resource, that is, a short time of use.

Multielectrode details

A feature of these parts is the presence of several side electrodes, which are located around the central one. Their quantity may differ. The principle of obtaining sparks is also different from the traditional. If one of the side electrodes wear out, the spark from the wires is transmitted by means of a working electrode, which increases the use of such a part, that is, its resource. The use of multi-electrode products allows you to increase the engine power index in the car. At the same time, fuel burns better, which is also the advantage of the operation of the product, the number of electrodes in which is increased. Such products are produced under the brands of DENSO, NGK and others. Under this brand also produces high voltage and incandescent candles.

Platinum and iridium products

Details that are made from iridium and platinum are distinguished by the fact that they are able to withstand large temperature loads. Platinum and iridium parts cause a large capacity of the car, and when the sparks from the wires are sparking, the part is self-cleaning due to the removal of a car from the surface of the electrode.

Forkarny details

Such varieties of the product is characterized by the forkar design of the electrodes. When the pulse is applied from the wires, there is a breakdown, localized between the surfaces of the electrodes. At the same time, the plasma bunch in the combustion chamber occurs. During this, the voltage of the fuel mixture is launched. The combustion products enroll in the engine cylinders at high speed.

It is worth noting that the ignition of the mixture has a bulk character, and not the point, as in the details of the classic design. The speed and completeness of the combustion of the fuel mixture increases, the engine power increases and reduce the toxicity of combustion products.

Produce such parts under the brands NGK, DENSO and others. Manufacturers produce many varieties of spark plugs, including such well-known brands like NGK and DENSO. Analog table can help with a choice of a suitable part for a particular car. When a car's configuration with a diesel engine may need incandescent candles, which are also produced under these brands.

Before choosing these details, you need to consider several rules:

The final choice of spark plugs depends on what car they will be used and what loads are assumed.
If we talk about the terms of use, you can divide products into three types. Yttrium parts are relatively inexpensive, but they need to be changed in 25 thousand mileage kilometers. Iridia can last twicear longer. The most wear-resistant products are platinum, but they are distinguished by the highest cost. The resource of the part is the most important parameter during operation.
Opportunity contactless ignition. Details with which it is possible to implement this, are able to ignite the combustible mixture using the spark charge moving between the electrodes. As an example, you can bring new NGK and DENSO products.

The process of selecting spark plugs and for foreign cars, and for domestic production vehicles should be carried out with special care. If you choose correctly, the engine power, and the duration of its uninterrupted operation will be optimal. To choose new spark plugs, it is necessary to take into account the estimated intensity of use.

The difference between the fuel ignition process in diesel engine Ensures the use of incandescent candles.

In a car using diesel fuelStarting the engine is due to the inclusion of the incandescent system. It provides pre-warm, which creates optimal conditions for running the motor. There are many grades of incandescent candles, including new - NGK and DENSO.

The correct combustion of the working mixture in the cylinders is determined by the productivity of the work and the full return of the engine. In a power unit running on gasoline, this process largely depends on the health of the spark plugs. This element requires special attention and regular replacement.

The topic of our today's article is the ignition candles, the selection of which is carried out in accordance with certain characteristics car Engine and elements themselves. Let's focus on this.

To date, the catalog of the spark plugs on the brand of the car is so extensive that every car owner can easily find the perfect products for its car. But for right choice SZ must know exactly how to choose a spark plug on a car brand.

In solving this issue, the knowledge of the basic parameters and performance characteristics of products will help, as well as the labeling applied on them.

Candle Denso.

Parameters SZ.

Choosing a NW, the car owner, often trusts the recommendations of the Seller or car service masters. But correctly pick up the product, in accordance with technical requirements Auto, you can independently. When purchasing product data, you must be guided by following:

SZ must ideally comply with certain sizes;
the glowing indicator must respond to a certain type of power unit;
SZ must be as high quality as possible and, most importantly, original.

We will tell you more about the main parameters of the SZ.

Calinal indicator

This indicator indicates the ability to cool and maintain the desired operating temperature of the electrodes during the operation of the motor. The roller indicator of the newly installed candles should correspond to the caliper value of the standard SZ, otherwise, the power unit will function unstable - "cold" copies will cover so much or begin to detonate - "hot" candles will overheat.

This value, which takes into account the degree of acceleration when starting the car engine. Elements that have a small value of the gallinal indicator (from 11 to 14) are suitable for engines with low loads. For power units having a capacity of 100 hp And higher from each liter of fuel, it is suitable for products that have "cold" (more than 20) or mean (from 17 to 19) the value of the gallinal indicator.

Selection of candles

Number of electrodes

Most often, motorists use elements with 2 electrodes - head and side. Although, the quality of sparking in such samples is no worse than the multi-electrode elements only at the initial stage. SZ, which are equipped with several electrodes on the sides, support the properties for a long time with the condition of their originality.

Note that multielectter models are charged between the main / central electrode and the side element, which is located closer to it. In addition, the wear of the electrodes in such samples occurs evenly. Suppose, when a failure or breakage of one of the electrodes is replaced by another, the working element. As a result, the electrodes will be replaced by each other until all of them break.

Material execution of electrodes

Basically, the NW is made from alloy steel, adding nickel and manganese to it. But today car owners are increasingly choosing candles with platinum or iridium.

Spark plug

Iridium spark plugs are equipped with a tip from this material.. This variety of candles is recognized as one of the most expensive, but extremely reliable, since iridium refers to the most solid metals. It is perfectly opposed to corrosion and electrojackers of different power. The size of the electrode in this product is approximately 0.6mm.

Platinum SZ. The electrode in these products has smaller sizes, but it is capable of providing higher power at the moment of sparking. What allows you to ensure high engine power as a whole. As many manufacturers declare, the period of operation of the platinum sample increases to 100,000 km. Due to the small size of the electrodes, this product provides a consistently low voltage in sparking, significant fuel savings and a permanent clearance during the entire period of work.

Products having platinum or iridium electrodes are working correctly with a runway increase to 100,000 km, but the price of a set of such SZ is somewhat higher than that of ordinary candles.

Geometry of products

The geometrical indicators of the SZ belong:

metric carving in the case (10x1.0, 12x1.25, 14x1.25, 18x1.5);
the length of the threaded part (9.5, 12.7, 26.5 mm);
the outer diameter of the hexagon (16, 19 mm).

The importance of accurate selection of SZ in size is justified Not only the convenience of installation and optimal sparking. For example, an instance having a "short skirt" will form ignition not in the central part of the combustion chamber, which will immediately affect the moment of ignition, in particular, on its timeliness.

Marking SZ.

Independent selection of spark plugs According to the brand of the car, it will be greatly simplified, if you read the marking applied to products. It provides motorists important information about the parameters of each particular product.

Marking SZ.

As an example, consider the label from the Bosch product with the index WR 17 DDC 9. It is decrypted as follows:

the W symbol is the metric thread rate (in this example it is 14x1.25);
the R symbol is the presence of a resistor that overwhelming a variety of interference;
value 17 - Calinal product indicator;
dD characters - the first is the length of the thread (19mm), and the second indicates the presence of one electrode with a side;
the symbol C - indicates the use of copper as a material in the manufacture of a key electrode.

Before visiting the store, follows pick up the appropriate modification, relying on a special table, taking into account the characteristics of the motor. Although today, with the help of special services, you can make a selection of spark plugs on the car brand online. This is a simple search form that allows you to make an optimal choice.

A variety of assortment of SZ.

Slightly above, materials were mentioned, from which the electrodes of SZ (copper, iridium, platinum) are made today. But it should be said about other varieties of candles offered by product producers:

Spark plugs of standard type. In these SZ, the main electrode is made from heat-resistant metal (alloy steel with the addition of manganese and nickel, copper). The period of operation of such products is not too long, compared with other varieties of SZ. But because of its affordable cost, standard SZ remains the most common and in demand.
Candles with multiple electrodes. A constructive feature of these products is the presence of additional electrodes on the sides. Their number may be different: from 2 and more. An increase in the number of electrodes is reflected on the period of product valid work. The main difference with the candles of the standard species is the ability to change the direction of the spark, because of this, the electrodes are "burning" much less.
Candles with V-shaped notch on the head electrode. Although the form of the electrode itself is slightly changed, it does not affect the life of the product. But, this ensures better ignition of the fuel mixture, which, for its part, affects fuel consumption and reduction of exhaust volumes.
Candles of the Forkarm type appeared on sale recently. In these products, the electrodes suggest a design in the form of a rocket nozzle (forms). When the discharge of high vulnery on the candle in the gaps of products appears a breakdown, and this leads to the ousting of plasma clots by means of pressure into the combustion chamber. At the same time, there is a lot of working mix in the for-chamber of the product. Combustion products at high speeds across the nozzle enter the engine, while forming the inflammation of the working mixture (ordinary candles provide point ignition). Due to which there is a solid growth rate, full combustion of the fuel mixture, the power of the motor increases, the toxicity of exhaust is reduced.

Variety of candles

Choosing a manufacturer SZ.

When buying spark plugs, car owners often get up to choosing that preferred - products recommended by a car manufacturer and work-oriented with a specific engine type, or buy affordable analogues. In a number of the largest manufacturers offering a wide range of SZ, you can allocate:

SZ Bosch. The company has already been offering high-quality and reliable products for more than a decade. In total, more than 20,000 different modifications were released. Buying original candles of this manufacturer, the car owner provides an effective, long-term and maximum engine correct operation.

NGK. Also proposed an extensive assortment range of SZ. Having almost a century of history, the manufacturer offers the highest quality products for mass production cars. The cost of one candle is approximately 100 rubles.

DENSO. The ignition candles are produced, which are used by the World Automobile Champion - Toyota. What is a guarantee of high quality quality DENSO products.

CHAMPion company - world famous manufacturer of SZ. Produces products of various types, in particular, and for two-stroke motors with a high rev..

When selecting the optimal option, it is necessary to take into account not only certain technical indicators, but also the recommended replacement period. With a small time, you do not need to purchase a product with a working resource in 120000km.

The good quality, for example, Finval / Brisk provides correct sparking and the optimal fuel consumption for the period until the next replacement.

Operating period

The procedure for replacing elements in the ignition system in the car, implies different deadlines for such actions. For popular cars, for example, Renault Logan. (2nd generation), Hyundai Solaris, Lada Priora, this interval is set at 30,000 km. Information on the frequency of replacement of spark plugs is usually contained in the technical documentation for the car.

With the intentions of connecting new candles, you should replace the full set, without considering the actual state of each element separately. In this case, the motor will not "troit", after a short period of time.

NW device

In the list of symptoms of violation of spar formation, marked:

significant increase in fuel consumption;
activated vibrations in the operation of the motor;
embarrassed engine launch;
"Dips" in work in some modes.

It should be noted that the manual to the car contains a list of the NW, which is recommended by the manufacturer at the time of its release from the conveyor. But the situation can be changed and the list of elements suitable according to the characteristics is often wider. To facilitate the choice there are relevant tables of the interchangeability of the NW, which are on sale.
In addition, special services work in the Internet space, allowing you to quickly choose candles on the brand and model of the machine. To do this, you will need to set the car model, VIN and the volume of the motor. Such services usually offer several options that are suitable for the specified TC model.
When buying candles, it should be carefully inspecting the elements themselves and their packaging. Products should not be chips, damage and defects. When buying new candles in a car shop, find out about the possibility of checking their performance on check equipment. It is guaranteed to have dealers with a good reputation.
In conclusion, we note that the choice of products on machines with HBO implies a serious approach. When buying, you should consult with installer masters gas equipment And ask the seller to carefully consider the decision of this issue.

Timely and complete combustion of the working mixture in the cylinder determines the efficiency and complete return of the car engine. In a gasoline force unit, this process will provide only a good candle. In the ignition system, this item refers to the number of elements that are subject to maintenance In the form of an independent operation. Before the next replacement, the selection of spark plugs by car is carried out on a variety of criteria that will ensure the stable and reliable operation of the engine.

The main parameters and their meaning

When selecting spark plugs, the car owner does not assume the presence of a large number technical parameters And more often relies on the choice of car service or seller. At the same time, clarify the main characteristics of the candle of a certain model is not difficult. Among the meaningful parameters are distinguished:

Number of electrodes. In most cases, copies with two electrodes are central and one side. According to the quality of formation of sparks, such samples are not inferior only at the initial stage. Candles with several side electrodes retain their properties for a long time under the condition of high-quality execution.
Kalil number. The indicator is taken into account taking into account the degree of forcing the power unit. Samples with a small indicator of the gawal number 11-14 are suitable for low-loaded motors. Motors with returns from 100 liters. from. From one liter work with cold (more than 20) or medium (17-19) values \u200b\u200bof a gallinal number.
Material of electrodes. The main material is alloyed steel with the addition of nickel and manganese. The service life increases by applying platinum electrodes. Fully platinum or iridium electrodes increase the service life of up to 100 thousand km of run, but increase the cost of the kit.
Geometrical dimensions represent several type indicators.

The need to accurately choose a candle in size is associated not only with the possibility of installation and a good formation of the spark. For example, a sample with a short skirt will produce a spark not in the center of the combustion chamber, which will directly affect the timeliness of ignition.

What will tell the marking

When choosing an ignition candle, the marking is able to give additional information on the characteristics of a separate instance. For example, the Bosch product with the index WR17DDC9 is decoded as follows:

the letter "W" - the value of the metric thread on the housing corresponds to 14 × 1.25;
the designation "R" - the presence of a resistor to suppress no interference;
index 17 - a calil number of candles;
serial listers "D" - the first indicates the length of the thread (19 mm), and the second indicates the presence of one side electrode;
the value "C" indicates the use of a copper electrode as a central one.

Before you go to the store, select a suitable model based on the manufacturer's table, taking into account the parameters on the engine. Specialized resources offer a simplified search form, where the ability to make a selection by car.

We choose the manufacturer

When selecting sparking items, the choice is usually between recommended engine elements or accessible analogs. Among the most famous brands With a wide range allocated:

Bosch spark plugs For, almost 90 years of history was released in terms of the number of models of more than 20 thousand, provided that the original products are purchased, the reliable operation of the engine will be provided.
Wide number of proposals NGK has a NGK, which has almost a 100-year history. When providing high quality, the cost for mass models of the car lies within 100 rubles per piece.
Candles ignition DENSO. Provide the work of the world car manufacturer champion - Toyota. The number of cars issued for 2016 exceeded 9 million pieces, which only confirms the quality of DENSO products.
Widespread Champion spark plugs are known for the production of parts, including two-stroke motor With a large number of revolutions.

When choosing suitable option, not only separate specificationsBut also take into account the interval of the recommended replacement. At small intervals, there is no need to buy a candle with a resource of 120 thousand km mileage. High-quality product, for example, Finval or Brisk will help ensure reliable sparking and optimal fuel consumption for the time before the maintenance.

Replacement frequency

The regulations for replacing the parts of the car ignition system provides for various frequency of such operations. For the most common machines, such an interval is set equal - Renault Logan (second generation), VAZ-2170 (Priora), Hyundai Solaris have an actual indicator at the level of 30 thousand km.

When planning the installation of new elements, it will correctly change the entire set of entirely, without taking into account the actual state of a separate candle. This will avoid engine starting when working in a short time.

Among other signs of violation of work in the formation of sparks, note:

tangible increase in fuel consumption;
the appearance of vibrations in the operation of the power unit;
machine launch difficulty;
dips when working in certain modes.

Online services for the selection

DENSO candles, you can pick up on that website.
Bosch candles are looking for on this resource.
Candles ngk can find here.

The operation of a modern car is designed for mainly service maintenance. Therefore, the manufacturer does not always provide the source characteristics that will help choose an analogue of a candle for a car. Even if Bosch will present such parameters, they will be difficult to use it difficult.

In such cases, it is convenient to separate the selection with regard to the modification of the car. It is usually enough to know such source data as the year of the car, the type and volume of the engine, the year of release. With difficulty in independent search, selection of spark plugs on a car brand trust the professionals.

It can be specialists of the nearest store of spare parts, a specialized online store or narrow-controlled service.

After processing the initial information, you will need to select the desired option from the number of available suggestions, taking into account the marking of the product. For example, for not the most common model - Ford Explorer 4.0 liters at the request of the spark plugs were immediately able to offer Bosch, Dance and VAG.

At the factory number of the car

The search for spare parts on the wines of the code is carried out in the case when the complete authentication of the car is required. This is relevant for rare modifications even known brands, relatively fresh models.

The principle of VIN search is similar to the work of search engines in the World Wide Web. Encrypted information in individual code is closely intertwined with similar spare parts ciphers. Therefore, even not knowing technical parameters, it becomes easy to recognize the desired candle.

For the task of the wines of the Win code, some options are available:

specialized Services search for spare parts with a task of a unique number;
search Resources integrated service online stores;
when contacting the service center by directory or search engines.

Before purchasing any set of candles, do not forget to check their state visually.

The purpose of the ignition candles, regardless of the volume of the engine, is the transmission of high-voltage charge, which is necessary to ignite the fuel-air mixture in the cylinders. If SZ for some reason fails, it will lead to not stable work Motor as a whole, so every car owner should know how to change the devices and which is better to choose. How is the selection of spark plugs in the car and which types of SZ can be found on sale - read it below.

Before choosing a SZ for your car, we recommend you to familiarize yourself with the main parameters of the devices. To begin with, consider their views.

Table interchangeability of the main types of SZ

Detailed manifold

Standard SZ. In this case, the central electrode is made of metal, which should be heat-resistant. The service life of such parts is usually not particularly high, if compared with other species. However, this type of SZ is considered one of the most common and sought-after.
Multielectrode SZ. In such devices, the design is supplemented with side electrodes, their quantity can be different, ranging from two and higher. The increased number of electrodes was reflected on the service life of the details as a whole. In contrast to the standard SZ, in such details the spark makes it possible to change its direction, as a result of which the electrodes are combined to a lesser extent.
SZ with V-shaped cut on the central electrode. Let even the form of the electrode changed, but this does not affect the service life of the device as a whole. However, this contributes to a better combustion of a combustible mixture, which in turn affects the consumption of fuel and decrease in exhaust gases.
Platinum SZ. Many motorists today stop their choice on platinum details, since they are electrode, although they have a smaller thickness, is able to provide better spark power. And this, in turn, provides the highest power of the motor as a whole. According to many manufacturers, the service life of platinum parts can be increased to 100 thousand km. Thanks to the small thickness of the electrode, the device provides low sparking voltage, fuel savings, as well as a stable gap throughout the life.
Iridiyev, in such devices from iridium, a tip is made. To date, this type of SZ is considered one of the most expensive and reliable, since Iridium is considered one of the hardest metals. It optimally opposes the formation of corrosion and various electrical discharges. The electrode thickness in this case is about 0.6 mm.
Forkarmed SZ not so long ago appeared. In such candles, the electrodes have an interesting design made in the form of a forkamer. When the high-voltage discharge is applied to the device in the gap, a breakdown is formed, which contributes to the deposition of a plasma cloth under pressure.

Caliv number of spark plugs

Buying details, initially pay attention to such a parameter as a calic number. This value is the designation of the time segment, after which the part will be able to give a voic ignition. Moreover, if the length of the thermal cone of the insulator element is less, this will ensure the most effective heat removal from the SZ. If you do not know which it is better to choose a NW, then first of all you should familiarize yourself with the service book to the car, where all the basic parameters of the selection should be indicated.

It is always necessary to remember that the use of components with a threaded 11 mm is not allowed in engines that are designed to operate with extended threads and vice versa. A part of the part that is installed in the motor cylinder is a source of gawal voltage, respectively, it may cause damage to the electrodes. Alternatively, under the extended device, you can install a rubberized gasket, but this option will prevent damage to the part only for some time (the author of the video is NRG61RUS channel).

Number of electrodes

As mentioned above, automotive SZ can have a different number of electrodes. The design of one-electrode details involves the presence of only one central and one side electrode. In multi-electrode devices, the number of lateral electrodes can be different. In such devices, the charge education is carried out between the main and lateral components of the structure.

One of the main advantages of the latter is that the electrode elements on the device wear out evenly. That is, if one of the components for some reason fails, it will be able to replace it with another, efficient electrode. Ultimately, these elements will change each other when you fail, while each of them breaks down (the author of the video for cleaning the SZ - channel is vailing together).

Rating SZ on brands and manufacturers

SZ Eyqiem 77 00 500 168. These are original devices designed for Renault K7M engines, respectively, their operating parameters and characteristics are optimally adapted to these motors. One of the main characteristics of the parts is a large departure of the electrode, which ensures the most optimal and stable ignition of the combustible mixture, even if it is unevenly distributed over the cylinder. In addition, this solution contributes to more improved ventilation of the device, which also ensures the stability of the ignition.
In accordance with the reviews, these candles are really as good as the manufacturer describes them. In fact, the resource of the operation of the SZ depends on the state of the power unit, as well as the quality of the gasoline used. The service life of Eyqiem 77 00 500 168 is on average in the area of \u200b\u200b40 thousand km of run.
DENSO K20TXR. In such details, the electrodes are coated with nickel, which contributes to more sustainable SZ operation, an increase in their service life, as well as immunity to erosion. If you look at these SZ through a magnifying glass, you will see that the side elements are installed as soon as possible, not even visible traces of soldering and distortion. Accordingly, it contributes to the improved formation of the spark and, accordingly, more stable operation of the motor, which in turn affects the consumption of fuel. The only disadvantage is the high cost of devices.
BERU Z193. SZ of this brand is characterized by affordable cost and sufficiently high service life. There are many different types of SZ BERU in the market, but this option is considered one of the most optimal for many modern motors. Due to the fact that the design of the parts itself is one-electrode, their service life will be lower compared to the devices described above.
Devices have a small spark gap, constituting only 0.9 mm. And although this largely facilitates the launch of the power unit, if car battery There will be a nasty, but also it helps to reduce the power of the spark. If, in addition to all, you will refill low-quality fuel, the use of BERU can cause ignition passages, in particular, during the operation of the DVS under heavy loads. In addition, due to the fact that the electrode is a bit recessed, it contributes to the deterioration of the spark gap ventilation, respectively, this may affect the ignition of the combustible mixture.
Bosch. Bosch brand has long established itself on the market as a manufacturer of high-quality parts and components. As the results showed the results of numerous tests, the products of this manufacturer in quality of performance are not inferior to even market leaders. At the candlelight, the electrodes are soldered quite smoothly, while the marking on the design is applied smoothly and without distortion. The presence of the latter may indicate that you have counterfeit SZ in your hands.
The main advantages of such devices should highlight a high service life, as well as enough low price. As for the shortcomings, this is a huge amount of fakes in the domestic market.
NGK. Iridium devices, of course, are the highest quality and efficient, and their service life will always be higher, compared with traditional SZ. Their operation, according to many specialists, is relevant on newer power units that do not "eat" oil. If you only use high-quality fuel to refuel the car, the service life of NGK can be 50 thousand km of run.
From the main advantages of devices, a stable formation of sparks should be allocated, as well as a fairly high service life. As for the shortcomings, this is a high price, but as you know, you always need to pay for quality.

Remember: Candles need to put such as the car manufacturer recommends!

Over time, the NW can form a nagar, contributing to their less efficient operation - in the video below detailed instructions Upon removal of nagar with a description of all the nuances (the author is the Channel of the RF Autolectrician).

Ignition Candle - What is it?

Constructive features

The above-mentioned device of the classic ignition candle was described, there are other types:

- Multielectrode: the main difference in the number of lateral contacts. The main advantage of candles this type - Their resource, of minuses - ignition pass are possible.
- Platinum: At the central and side electrodes, platinum attack are located, sometimes another drag. Metal. They are less susceptible to the formation of Nagara at work points, ignition skipping is almost minimized. Candle resource up to 50 thousand kilometers according to most manufacturers.
- Iridiev: The central electrode is made of iridium, the side electrode has a U-shaped groove. The service life is higher than that of platinum, sparking is almost perfect. Of the minuses you can mark a rather high price.
- Forkarm: candles of fundamentally different design. They are installed in the depths of the chamber chamber.

Principle of choice

In Russia, candles are released with numbers 8, 11, 14, 17, 20, 23 and 26. The lower the value, the "colder" the candle.

Imported there is no single scale. To prevent problems with the ignition system, it is best to familiarize yourself with the instructions in the car's service book, there is information about what type, brand and model are recommended, and you can avoid many trouble with the engine. Do not follow the instructions have a good chance to get on overhaul Engine, and this is already a very sad story, including in finance. Thus, the selection of spark plugs on the vehicle brand is the most correct option.

Resource candles

Normal in this case, the Nagar will be from coffee to light brown. Black spark plugs Cause - excessively enriched mix white flag The ignition candlelight is a depleted mixture, a red - low-quality fuel with additives to increase the octane number, erosion - the candle worked for the reasonable life, the ash is oil in the combustion chambers (the rings or the cylinder rings fell).

But the ignition system consists not only from the candles, but also from the coil or the ignition coils and high-voltage wires. It is through them that the high voltage is supplied. They must be checked for integrity and resistance. Resistance value can be easily found in general access. If there is a breakdown on high-voltage wires, but the spark does not occur on the electrodes of the candle and the corresponding portion of the fuel and air mixture will not ignore. This will be expressed in the "Trojoint" of the engine. Now many manufacturers try to strengthen the spark. And it is even good on one side - uniform combustion, less emissions harmful substancesBut the stronger the spark, the less durable product you will receive, and also do not get around the temperature erosion.

The most common cars in Russia and candles to them

Now we can say the ignition system reached the maximum of their evolution. In this regard, many even famous manufacturers are forced to make marketing moves, in fact calling old solutions with new terms. Spark plugs do not have a single label, but many are interchangeable. There are special tables for the selection, but still the main characteristics are the size, a gauge, the gap between the electrodes.

It is best to set exactly those options that the car manufacturer recommends.

Many motorists try to buy more expensive candles, such as platinum or iridium and use on cars of old years of release. Of course, it will not be worse, but there will be no additional advantages, this is due to the engine design. This purchase will simply be economically not appropriate. If cylinders are worn, for example, the oil will be without a difference from what metal is the electrode is made. And as an additional recommendation, add, refuel, if possible, only on verified gas stations. The quality of the fuel depends on the condition of the candles, including.

And how do you pick up the spark plugs for your car?

How to choose spark plugs for a car?

The competent selection of spark plugs on the car is necessary to obtain the maximum return of the engine and the operation of the motor. In a huge number of models and manufacturers, it is sometimes difficult to figure out, so the advice on the competent selection of candles will not be superfluous.

Multielectrode Ignition Candle

Selection of spark plugs

Spark plug parameters important to install in the motor are the diameter and length of the thread shank, the size of the hexagon for wrap. Strict requirements are presented to carving, and the sizes of the hexagon can vary in some cases.

Geometrical parameters

The diameter of the thread corresponds to the one that is cut into the block head, otherwise the candle will not fail, or fall into the hole. The length of the thread is equal to the proper and safe job: When applying shorter, we will take the spark interval inside the hole in the cylinder head (GBC), the gap ventilation between the electrodes deteriorates - ignition interruptions are likely. Thread Threads, which remained free, are covered by Nagar, and the wrapping subsequently "correct" candle will damage them, worsen the reliability of fastening and tightness. Similarly covered by nagar and thread, if it is longer than the desired - the thread in the aluminum head will suffer already when turning. On modern motors with compact combustion chambers, the candle with an elongated threaded part rests on the valve when opening or in the piston, so that the motor with such a candle will not be able to work.

Marking NGK BPR6es.

Each manufacturer has its own marking, so the selection of analogues should be produced, first deciphering the labeling of standard candles, then select the desired encoding of another manufacturer. If the car is regularly worth the NGK BPR6ES candles, the first letter B indicates that the diameter of the thread is 14 mm, and the length describes the letter E - 19 mm.

Marking of domestic candles

As for the hexagon, then it is necessary to follow its size only in motors with dual heads (DOHC), where the candles are recessed into wells - the larger hexagon will not enter the well. In motors where candles stand on the side of the head, there is no fundamental value, whether the size of the hexagon corresponds to regular candles, except for the second candle wrench.

The design of the setting assembly of candles includes the type of seal - the metallic ring-gasket was originally used, which are compressed when tightening. On 16-valve engines, where, due to the small diameter of the skirt, the gasket would not have enough area, a conical seal is applied - the candle applies itself, presses the conical part of the skirt in the chamfer on the hole in the head. New candles must correspond to the type of compaction by standard - candles with a cone are not sealed in the heads, where the hole is calculated on the use of the rings-gasket.

Candle replacement table of various manufacturers

Table of replaceability of domestic candles A17DV and A17DVR-10 on analogues of imported manufacturers

Kalil number

The calil number determines the cooling ability and supports the desired operating temperature of the electrodes when the engine is running. The calil number of new candles corresponds to the caliper number of standard, otherwise the engine will either begin to work with interruptions (too "cold" candles will be chopped by nagar), or will be detonated (too "hot" overheat).

The marking of a calil number has its own, and may even differ in the direction of growth in numbers. Therefore, when choosing a candle, focus on the consolidated table:

When you choose the candles of other manufacturers, find the matching tables or use the manufacturer's catalog by car brands.

Construction of electrodes

Video: How to pick up candles to a foreign car

In contrast to geometric sizes and a calil number, the design of the electrodes varies. What is in this case to pay attention?

First of all, on the departure of the electrodes relative to the skirt. On Motors with multiclap heads, where the candle is standing in the center of the combustion chamber perpendicular to the piston, candles with a small departure are used - sometimes the central electrode is recessed inside the skirt. This is necessary primarily for the layout reasons - less likely to "meet" with piston and valves. Two-pant heads use candles with a large departure of electrodes. What is it for?

On the same candles we see two side electrodes. Such constructions that contain 2-4 side electrodes are designed to increase the candle resource (and not to receive a "multiserry" ignition, as some believe) - when due to wear, the gap between the working pair is increasing, the spark beats between the neighboring, where the clearance is less. There are also minuses in such candles - additional side electrodes worsen the ventilation of the spark gap, create an aerodynamic shadow.

Therefore, there is no point in increasing the number of lateral electrodes - the resource of the candles depends on the quality of gasoline, but some deterioration in the operation of the motor with multi-electrode candles is possible on motors where the conditions of ignition and are so far from ideal - when Euro-4 firmware is placed on engines designed yet In the 80s and unable to adequately work with conceded mixtures initially. When changing regular candles on multi-electrode, we discover the growth of vibrations on idling: Just affect the degraded ventilation of the spark gap.

Clearance between electrodes

Video: Alphabet spark plugs for inexperienced and self-diagnosis

Even in one series of spark plugs, there may be several options that differ in the gap. At the same type of candles NGK BPR6ES-11 and BPR6ES-12, the difference in the gap: in the first case it is 1.1 mm, in the second - 1.2 mm.

The only case when you can move from the standard gap - this is a replacement of spark plugs on iridium: electrodes ensures confident ignition of the mixture and with a smaller gap, and these candles reduce the load on high-voltage chains Ignition, since the gap between thin electrodes makes itself easier. Therefore, manufacturers of iridium candles indicate functional analogs of candles with gaps 1.0-1.2 mm Iridium with a 0.8 mm gap.

Unconventional structures

Always want to get from the larger engine, and many use it: remember at least recently advertised candles "Bugets", allegedly providing unrivaled efficiency, increasing power and so on. The conservatism of world spark plugs manufacturers are not inertia of thinking: improving decades of construction is difficult to improve decades.

The breakthrough was at one time the appearance of iridium and platinum candles was the appearance of iridium and platinum candles - they are superior to the usual, but the price is also distinguished.

Spark plugs - selection by car in different ways

The stable operation of modern vehicles in a large extent depends on the spark plugs. In the competent selection of fuel in the motor, the car braids the most effectively and efficiently, which makes it possible to reduce fuel costs.

1 Kalil number - Let's start with the main

The spark plugs are necessary for ignition in the cylinder of the air-fuel mixture of the air-fuel mixture at a certain time interval. The device you are interested in are located with special electrodes, between which the spark occurs when the electric power voltage passes. It provides the ignition of the mixture. The correct work of the candles depends on a number of factors. We highlight the main of them:

Compliance with the characteristics of the candles and motor capabilities of the motor vehicle.
Operating indicators of materials from which the ignition devices are made.
Features of the candle design.

A key characteristic of devices for fuel mixture is considered a calic number, which is an integrated temporal value. It defines a certain period, after which arson takes place. Kalil number for products different types It is installed individually and depends on the indicators of their heat transfer. As a rule, it is equal to 500-600 ° C. Car manufacturers advise to pick up candles of certain types, considering the technical characteristics concrete Engine.

Here you need to know the following. Select the spark plug is necessary so that it does not appear on it at work. In the combustion chamber of the car motor, there is always a small amount of oil. It spontaneously enters the insulator and electrodes. If the calil number is in the recommended temperature range, the oil burns without a residue. Due to this, the ignition device self-cleaning and functions without breakdowns for a long time.

2 Construction, dimensions of ignition devices - how many electrodes need?

The sizes of candles have no less value than their calil. If you purchase and install products with unreasonably large length, they will be overdressing. And short candles in relation to the combustion chamber will be too far. In both cases, the inflammation device will not be able to qualitatively perform its functions.

Also, the spark plugs differ from each other with their design. Most often, modern motorists are dealing with devices that have a cup of carvings and metal housing. Such products are considered standard. In them, the spark arises between the central and side electrodes. The main advantage of such structures is a low price, disadvantages - the impossibility of the full use of engine capacity and the low life of the candle.

Devices with a central (one) electrode and four (or three) side are considered more efficient in work. In them, the spark arises strictly in the center of the candle. It provides high-quality and rapid ignition of the air-fuel composition. In addition, if one of the side electrodes fails or contaminated, the arson of the mixture will still occur. In such cases, the spark simply jumps over to the adjacent element.

Devices with 4-5 electrodes increase the environmental characteristics of vehicles and allow them power installations Show all your power potential.

Another point. Multielectrode designs in recent years are becoming more subtle. The standard cross section of the electrodes is 2.5-3 cm. But recently it has been proven that the spark is the more powerful than thinner electrodes apply. This was the reason for creating products with a thickness of less than 2.5 cm. At the same time, a new problem arose. Thin electrodes made from nickel (it is most often used for the manufacture of candles), unable to withstand increased loads. Manufacturers had to look for new materials. About this next.

3 Materials for the manufacture of candles - what better?

Classic electrodes are made of nickel alloys. They cannot be used to create contemporary products due to the above. Nickel designs have a number of operational minuses. They are:

make it difficult to get a cold start of a motor;
tend to pour in the cold season;
require frequent replacement.

Platinum candles are changing every 90-100 thousand km. Autoexperts advise them to put them on power units complex configurations. In this case, the high cost of devices will pay off their durability and trouble-free operation. There is no point in the old Soviet and modern Russian cars to establish such candles. You just spend money in vain.

Iridium candles are even more expensive. They increase the power of the car, guarantee the quickzzi of the fuel mixture, they have economical fuel consumption. The need to replace such structures occurs no more than in 80-100 thousand km of mileage. Products from Iridia have proven themselves on machines with conducted engine turbine.

4 Selection of components for sparking - Standard techniques

On the candlelight of Russian manufacturers, the magnitude of their thermal cone is always indicated. In theory, we need to purchase a device with the same labeling and install it on the car. Unfortunately, this technique does not work. The knowledge of the magnitude of the cone does not allow you to truly qualitatively choose products for a particular engine model and vehicle brand. The problem is solved if we are talking about cars of the last 10-15 years of release (both import and domestic). Manufacturers in the manual for their iron horses Clearly indicate what candles you can replace the factory components in case of failure.

And what to do the owners of old vehicles and cars that do not have instructions for use? Purchase the necessary spark plugs in this case is difficult, but you can, the selection of products by car do this:

Unscrew the old product from the motor.
We find labeling on the body of the part.
We go to the auto shop and select the appropriate element on the index.

If the desired component model is not, we ask the advice from sellers consultants. Perhaps they will be able to tell than replacing the device you need. Here you have to hope for their professionalism and good knowledge of the range of autocroducts.

Note! The described method of selection of inflammation devices is suitable only for cases when you are exactly sure that the car has the right candles.

5 Choose and acquire spark plugs in a new way!

Modern technologies made the life of motorists much easier. With the help of online services, they may pick up and order spark plugs without leaving their cozy home. The network has a lot of special sites on which a variety of devices for obtaining sparks are sold. There are among them and unique services, where the consumer can independently choose components, knowing the VIN code and the volume of the motor, as well as the brand of its car.

A lot of drivers are charged and the purchase of ignition devices on the NGK Internet site (https://www.ngk.de/nc/en/podbor-produkcii/). An understandable interface and a huge site database allows any vehicle owner to choose the detail of the car's brand. More simple option The search for the desired item does not exist!

NGK is a very convenient, but not the only online service available to Russian motorists. We can also use the Bosch electronic directories (http://bishka.ru/catalog/svechizazhiganija/) and Denso (http://www.denso-am.ru/elektronnyi-katalog/). They make it possible to pick up candles on the car brand, companies producing spare parts, type and component models. A child will cope!

Regular replacement of ignition devices - a pledge of long-term operation of the car. Do not be lazy to perform this procedure. And then the machine of the car will delight you with its stable operation at maximum power. And O. big flow Fuel you forget forever!

How to choose a spark plug on a car brand

The operation of the spark plugs in the car becomes noticeable most often after a long use of poor-quality fuel. Gasoline consumption increases, the motor is becoming less direct, sometimes starts to told. In these situations it is worth conducting primary diagnosis of candles. In the event of identifying problems with this part of the car electrical system, you need to go to the store and make the selection of spark plugs on the car brand.

Correct work of candles in the car

The problem of automotive spark plugs is to ignite the fuel mixture inside the engine cylinders. This happens after the filing of high voltage to the candlestones. The correct uninterrupted operation of the device in the system depends on several factors:

structural parameters;
used for the production materials;
the ratio between the characteristics of the product and the motor.

To properly choose the spark plugs on the car brand, it is necessary to consider the recommendations of automakers for each model of the vehicle.

Ignition candle device

In auto operating instructions, you can often find a list of analogues that were produced at the time of manufacture of the machine. Also, there are lists on the official websites of automakers.

You need to know that in addition to geometric characteristics, the driver is obliged to be guided by a calil number for candles.

Its value is associated with the efficiency of material heat transfer and thermal modes of the candle. A larger digital indicator of this parameter corresponds to the increased temperature values \u200b\u200bin which the part is maintained. This means that for the forced sports motor, it is necessary to select the maximum value of the gallop number of candles, otherwise they will be subjected to the ending overheating.

Selection of experienced way

The right choice of spark plugs on a car brand can be done using simple actions. Of own car Alternately unscrew the candles from the sockets and record the visible parameters of the product.

Candles with marking

In any specialized car on product packaging, the same parameters are indicated. A competent seller-consultant will help to deal with marking or offer a similar item. We select the appropriate product and install in place.

This option will be suitable if the car owner is confident that no incorrect change in the ignition system has not been carried out. Owners of domestic machines, the plant facilitated the work on the search, making the table of interchangeability. In addition to local products, foreign products included in them.

Selection of internal design

Deciding with geometric characteristics and a caliling number, it is worth paying attention to structural features. In car candles, the main difference in this parameter is noticeable in the electrodes.

One electrode

The classic design assumes the presence of one electrode. The part of this type consists of a ceramic hull located in the upper part and a metal cylinder with carvings. The discharge of electricity forms a spark between the central electrode and the side.

Candles with one electrode

External changes that relate to such a design were experiments with the diameters of the electrodes and the length of the threaded part.

The positive qualities of this option consist in low cost. The disadvantages include a relatively short service life and the inability to complete the potential of the power plant.

Popular models in this area are NGK BRP6E, DENSO W20EPR-U, BOSCH WR7DC, CHAMPION RN9 YCC. The latest copper side electrodes are built into the latter, which makes it possible to increase the resource of developments almost 2 times due to the reduction of the operating temperature.

In NGK, we decided to split the tip of the central electrode. Such a move was able to extend the work of the candles, because the spark will go to the metal part with a smaller Nagar. Accordingly, even if one "tongue" does not work, then the second, cleaner, will miss the discharge. A similar principle was adopted in DENSO, but "rapid" side contact.

Several electrodes

Attempts to split the tip of the electrode naturally resulted in the manufacture of candles with several such elements. As a result, candles were created with 3-4 lateral independent straight electrodes. Externally, the working head began to resemble a blurred bud.

Several side electrodes

The design has received many advantages, because the spark did not block the side electrode, which helped it easier to ignite fuel mixture. Sparking was formed from interaction with any clean contact.

With this location, the fuel managed to heal faster and completely thoroughly, so emissions were cleaned, and the car's power is higher.

Benefits include affordable pricewhich is slightly higher from the cost of a classic manufacturer.

The following models have a similar design: NGK Bur6et, Brisk DR15TC1, BOSCH W7DTC, ULTRA-X. Adherents of a particular brand can safely go to multi-electrode candles, supporting the favorite manufacturer. The effect will be seen immediately.

Refractory materials

Improving car candles, engineers began to use precious metals type platinum or iridium. The rationale for this is the temperatures withstanding with these materials.

Although the price of such products from $ 20 and above, but car owners establishing them in their cars reasonably argue their noticeable work on fuel economy. We can notice approximately 5-7% of gasoline savings. For carburetor models, the bottom of the interval will be closer. However, with a bonus they will have a motor and fuel system.

Iridiyey electrodes in candles

After conducting simple calculations, it can be determined that even such a high price "will command" savings with an average road in 3-4 months.

Drivers sports cars Noticed that if the central electrode has a thinner diameter than other structures, the spark is formed more powerful. But small size can quickly burn out. Therefore, iridium and platinum electrodes appeared, which are able to withstand significant overheating.

Changed and the direction of filing spark. Now the voltage comes from the side electrode, and this makes it possible to cleanse the thin central rod from the car.

Positive qualities of candles with refractory electrodes:

long term work;
self-cleaning from possible nagar;
increase dynamic and environmental properties power plant;
saving At fuel consumption.

The DENSO IRIDIUM POWER model is equipped with an electrode in the central part with a diameter of only 0.4 mm. German engineers in the Bosch Platin candlelight almost completely packed the axial contact in the ceramics. This significantly extended its service life by reducing the temperature effect on the metal part.

The Beru Ultra-x Platin model is made in the form of a multi-electrode design with axial platinum contact and four side. Engineers from NGK tried all electrodes from precious metals, as a result, the DFE model appeared, in which the central part of the iridium, and the side contacts from platinum.

Remote selection of candles

A popular way to buy spare parts via the Internet did not bypass automotive parts. To order online, you need to visit one of the proven resources, such as denso-am.ru, make an order, pay for delivery and wait for the courier. Seller for proper selection It will be necessary to provide data on the car brake, the volume of the engine and the VIN-code of the car. This information is entered into a special service designer.

Conclusion

Selecting the candles for your car, it is necessary to be guided not only by a low price, but also durability. The second factor will help save much more. Quality candles will serve longer and during operation will create fewer problems. This will positively affect the other elements of the fuel system.

Ignition Candle - a device that flames the fuel-air mixture in the engine. Its incorrect operation leads to three main problems: unstable engine operation, its complete stop, fuel overruns.

Main characteristics:

Kalil number.
The degree of self-cleaning.
Spark gap.
Number of electrodes.
Thermal characteristics.
Operating temperature range.

Each motor requires their candles, the wrong selection will lead not only to deterioration of the motor, but also to other serious problems.

The main characteristics of the spark plugs

In addition to the general characteristics, such as the service life (measured in kilometers) or the price / quality ratio, the candles have accurate.

Kalil number

The main indicator to pay attention to. It shows, with what level of pressure in the cylinder may be ignition - the ignition of the mixture is not from the spark itself, but on contact with the candles.

IMPORTANT! A calil number must match the number for a particular engine. Specialists admit a short-term use of candles with a higher KC, which is indicated in the specification to the motor, but categorically do not recommend candles with a smaller number. Otherwise, the engine will be seriously damaged.

Degree of self-cleaning

Spark gap

This is the name of the gap between the central and side electrodes. For each type of candle, it is not worth the adjustment. If it has been changed as a result of damage or marriage in production, it is more profitable to refuse it from such a candle than to try to fix it.

Number of lateral electrodes

Standard design assumes the presence of two electrodes: central and lateral. There are 3- and 4-electrode on the market. Their number increases the stability of the spark formation process, makes the engine work stable. In addition, the more electrodes - the longer the candle serves. The widespread view is that the more electrodes, the more Iskr arises - erroneously. Several sparks arise in candles without side electrodes, but this type is not very widespread due to high costs.

Working temperature

The norm for this indicator is from 500 to 900 degrees. The downgrade will lead to inlets on the insulator, which will cause the instability of sparking. Too heat Leads to the uncontrollability of the vibil ignition, which reduces the power of the motor and reduces the lifetime of the candle.

Thermal characteristic of the candles

The indicator shares the candles into two types: "cold" and "hot." "Hot" are designed for engines where self-cleaning temperature is needed at low temperatures. Candles, the thermal characteristics of which are higher than those recommended by the manufacturer will cause uncontrolled caliling ignition. "Cold" are applied there, you need heating below the temperature of the gauge ignition at the maximum engine power. Too cold candles for this engine will not be heated to the necessary self-cleaning temperature, which leads to rapid wear.

Top 10 best spark plugs

As in any other ratings, the distribution of positions in Top-10 depends on the one who was. Effectively make your own rating based on the use of products of certain brands. In addition, usually the manufacturer indicates - with what manufacturer it cooperates.

So, Bosch candles stand in all cars Toyota and a number of other global giants. NGK works with Volvo and BMW. Champion supplies products for Suzuki and Volvo. BRISK - for Audi, Opel, etc.

In addition, different brands produce candles of different types. Therefore, in the case of 4-electrode candles, the manufacturer may be in the first place, and in the 2-electrode rating - on the fifth.

NGK B9EG-3530. Leadership primarily because it is established on most cars collected in Russia. Accordingly, such candles are widely represented in retail. Cons - a large number of fakes NLC.
NGK BKR6EIX (6418). Despite high costPopular in Russia. Recommended for new engines and high-quality gasoline.
BERU ULTRA-X 79. The main advantage is the price / quality ratio. A large number of counterfeit.
DENSO PK20PR-P8. Stable high quality production, one best in the market of wear-resistance indicators and resistance to spark erosion.
BRISK EXTRA DR15TC-1. High performance indicators. Thanks to the original design of the candle, Brick significantly increase fuel economy and minimize the number of fakes. Minus - high price.
Bosch Platinum WR7DP. The position of the German manufacturer could be higher, but its products are designed for the German quality of fuel and roads. In Russia, it is not going to count on it. Nevertheless, durable - 55-60 thousand kilometers. Minus - a large number of fakes.
NGK BKR6EK (2288). Widely distributed, durable and economical. Competitive price. But on the market too much counterfeit, which is difficult to distinguish from the original.
DENSO K20TXR. Due to nickel coating is durable, resistant to erosion. Economical fuel consumption, acceptable cost. It works bad if the gas engine (HBO).
BERU Z193. Popular largely at the expense of the price. Oriented on the average driver, not loving often ride at high speeds. Not too durable, compared with analogues. Due to low prices, they are practically not formed.
Bosch FR7DCX. Domestic products, developed by German engineers. Quite high quality assembly, suits many Russian brands. Not very suitable for automatic transmission.

Marking

The label contains data on the factory, material, the values, the magnitude of the gap and constructive features concrete juicy. Difficulties with labeling are related to the fact that if in Russia it is one for everyone, then the world manufacturers have their own. The compatibility tables of all or most popular manufacturers in 99% of cases have sellers. Or they can be found on the Internet.

Replacement frequency

The standard service life of ordinary candles is about 30 thousand kilometers. For manufactured precious metals can reach 100 thousand. This is influenced by many factors, first of all - the quality of fuel. Also among negative factors - temperature drop (compression / enclosure) and environmental humidity.

IMPORTANT! Signs of problems: The machine twitches, the engine starts not immediately or stalls, the flow rate of fuel grew. It is worth inspecting the candles. It is necessary to change if: there is oil, soot on the electrodes, the insulator changed the color and lounted or there is damage.

If you regularly diagnose the machine to a hundred, where there are appropriate equipment, avoid problems easier.

Features when selecting spark plugs

The most important rule is to pick up candles based on your own experience. If it is small, there are several simple rulesTo make the right choice:

In size, the candle must be chosen exactly that stood before.
The calil number is exactly like the old one.
Multielectrode candles durable.
More expensive candles manufactured using precious metals reduce gasoline consumption by 7%.
The size of the gap between the electrodes. Experts recommend that it be in the range of 1 - 1.3 mm.

How to determine the type of candle on the car brake

First of all: to pick up the spark plugs on the car brand, you need to read the technical guide. There are options for replacement. If the car is purchased "from the hands", it is worth carefully examining the marking and search for information about how this candle is suitable for which it can be replaced. For example, it is believed that candles are well suited for Opel (REKORD).

You can seek advice into an auto shop or search for relevant information on the Internet. For example, "Pick the Denso spark plugs on a car brand" or "which SZ to put on Lifan 1.8".

Selection of candles on wines code

VIN-code - auto auto identification number of 17 digits. It contains data on the manufacturer, characteristics and year of release of the machine. It is in the serviceport and is applied by the manufacturer on the body of the body, the least prone deformation at an accident.

There may be several such places: the front left front desk, the left upper part of the torpedo, under the sheaving of the floor under the driver's seat, under the hood, etc.

The easiest way to choose the spark plug on the wines code is to use online services. For example, the easiest way is to choose the denso spark plugs under the brand of the car on the company's website.

Online SZ selection services

To minimize risks when buying candles through online services, first should be examined by user feedback about them. For this, large motorists forums will be suitable. There you can ask a question and ask for recommendations. For example, "if the difference between candles on Mazda 6 2.0 and 2.3" or "Dance Power Reviews"

IMPORTANT! Many such sites offer assistance consultant. To do this, call the VIN code and leave your contact details. After that, the seller contacts the client himself and helps to choose the goods.

For additional guarantees, you can try to find a service whose office is located nearby.So it will be easier to submit complaints in case of conflict with the seller.

Immediately after the purchase is delivered, it must be opened (unless otherwise specified) and check for originality and performance.

As in the case of other goods, you need to understand: what is more expensive, the better. However, in the case of candles there are nuances. For example, put the most expensive candles on the old gas or even relatively new models of the vase is not worth it.

When replacing the old candle to a new one, the latter must accurately coincide with the old one. The same applies to a gallinal number.

Multielectrode SZ is more expensive, but more profitable.First, they give a better spark for fuel. Secondly, if one electrode comes out of standing, another will change it. Thus, the candle will serve longer.

The most expensive electrode - Iridiyevoy, such candles serve longer than all.

Caliv number of spark plugs

This is the characteristic of the automotive ignition showing with what pressure begins to appear the calily ignition - ignition of the mixture from the candle housing.

In Russia, there is a single scale of KC - from 8 to 26. "Hot" candles - from 11 to 14, "cold" - from 20 and above. Foreign manufacturers prefer their schools. To determine the interchangeability of the candles, you need to find the corresponding tables on the Internet.
