What candles are better for VAZ? Candles for VAZ injector 8 valves.

09.11.2019

Replacing candles with a VAZ 2114 is a mandatory and regular procedure. In a car service, such a service costs from five hundred to one and a half thousand rubles. To the delight of reasonable and economic car owners, it’s not at all necessary to go to the salon: replacing spark plugs on a VAZ 2114 is a simple task. Even a new car enthusiast can cope with it on their own.

When is it time to replace the spark plug?

The interval of operation of one set of candles is usually designed for fourteen to twenty thousand kilometers. Although, the terms that manufacturers set are much longer - thirty thousand kilometers. Perhaps such a significant difference in numbers has developed due to the large number of counterfeit products in the modern auto parts market. And, nevertheless, if you trust the opinion of experienced car owners, then it is better to carry out the replacement procedure early rather than late.

What troubles they can bring in a used condition:

Significantly increase the consumption of gasoline.
The cost of running a car will increase.
Starting a cold engine will become difficult and take a long time.
There will be misfiring.
The operation of the engine will cease to be stable.

Useful advice: often economical drivers postpone the purchase and replacement of candles on the back burner. This is mainly done for reasons of economy. But, as you already know, when heavy wear significantly increases the consumption of gasoline and visits to gas stations are becoming more frequent. Do not get carried away by the illusion of savings, replace regularly.

If your car managed to roll out an impressive mileage on one set of candles, and the traction of the car began to weaken, then replacement of the candles is already necessary for your VAZ 2114.

Is there a difference in brands and manufacturers

There is a difference and it is significant. Before buying new candles, you should once again look into the car's operating instructions and check which marking is right for your car. On the VAZ 2114, the replacement of spark plugs can be from both domestic and foreign manufacturers. Carburettors with contact ignition will fit the A17DV candle with a gap of 0.5 millimeters. Carburetors with contactless system it will do the same, but with a gap of 0.7 millimeters. For those who have injectors, A17DV-10 by 1.3 mm is more suitable.

What may be needed

Before you get started, stock up on:

Special candle key;

A small bottle of compressed air (or a tire compressor instead);

compressed air tank

Brush for cleaning from burning and dirt;

Already bought a set of new candles.

Replacement procedure

We turn off the engine and be sure to wait until it cools down;
Raise the hood cover, fix it in the open position;
If your engine capacity is 1.6 liters, then you will have to unscrew the fasteners and remove the plastic cover (owners whose engine size is below 1.6 liters are not threatened with this procedure, because they do not have this plastic cover on their car);
We pull out high-voltage wires for rubber caps;
We remove the formed dirt and soot with a brush;
We unscrew the candle by throwing a candle key on it;
We repeat the same actions with the remaining old candles;
A new candle should be examined again, check the gap between its electrodes;
To start, spin new part by hand, not by a tool, this will protect the thread from breaking if the installation suddenly turns out to be incorrect;
We continue the twisting procedure, but with a tool;
We reconnect the high-voltage wires we removed earlier (the BB contacts should fit snugly in the candle).

Attention! Common mistake beginner car enthusiasts. Leads to each candle high voltage wire. In no case should they be confused. Connect the wire to the cylinder in series, following the marking rules.

You should not twist the parts with particular frenzy, their threads from rough force movements can be severely damaged.

After replacement

Unpleasant surprises can await car owners even after the old ignition parts are replaced with new ones. This can happen if the store sold you a bad, faulty candle. In this case, the engine twitches and runs intermittently. Naturally, the defective part must be changed again. And in order to determine which one is faulty, you will have to disconnect the explosives one by one. When the wire with a faulty spark plug is disconnected, no changes in engine operation are observed.

How to extend the life of a candle

The idea of extending the life of our part seems very attractive. The question is how to do it right? Some drivers are sure that with a leisurely ride, the candle will last them longer. And they are wrong! Candles really clean themselves, that's only when fast driving. At high revs engine - it is released from the resulting soot.

In addition to high speeds, you can extend their life by regularly checking the clearance. The latter must be within the framework established by the factory.

Carefully choose new spark plugs to replace. They should fit your car as well as possible.
In winter, before you start driving, let the engine warm up well.
Do not under any circumstances burn candles.
Always carry an extra set of new spark plugs with you.

Good luck on the roads!

Spark plugs are one of the most important parts in any ignition system, so their choice and further operation should be approached very responsibly. Depending on the type of candles chosen and the quality of their installation, it will depend on how stable and, most importantly, how timely the sparking will be, which directly affects the quality of the engine.

Consider the main characteristics of candles:

Heat number. It is not by chance that this characteristic is first on our list - focus your attention on it when buying candles. It shows the pressure in the engine cylinder at which glow ignition occurs. The indicator must necessarily correspond to the parameter set for the engine of your car.

Advice. If you could not find candles with the required glow number, and the car urgently needs to be on the move, short-term operation of candles with a higher glow number is acceptable. Do not allow the use of spark plugs in your car with a parameter that does not correspond to the specified one - this is fraught with burning out of the valves, breakage of the head of the engine cylinder, etc.

Gap. This is the distance between the “core” and the side electrode. If in any way it has changed, then you can restore the previous distance manually, but the best way out in this case is to replace the candle (as they say, "out of harm's way").
side electrodes. The standard spark plug design has one electrode. But in many modern models there are several side electrodes (2,3,4 pieces). Some mistakenly believe that the more ground electrodes, the greater the number of sparks created. This is a fundamentally wrong opinion. There will still be only one spark - the process of its formation will become more stable, respectively, at low speeds the engine will work more stably. Recently, candles without side electrodes have gone on sale. In such models, indeed, a spark is formed several times, at different intervals. Thus, a so-called "walking" spark is created, which provides better ignition of the mixture. Due to the (more complex) technology used to create such candles, the price of the product is significantly higher than traditional models.

Working temperature. It ranges from 500 to 900 degrees in any mode of engine operation. If the temperature drops below the minimum limit, then carbon deposits form on the candle insulator - it can short-circuit the candle gap. When the temperature rises above the maximum allowable limit, glow ignition will appear. Since this process cannot be controlled, it can lead to engine malfunctions.
Thermal characteristic. It is expressed as the dependence of the insulating cone and core on the operation of the engine. Candles are divided according to this criterion into two main categories: “cold” and “hot”. The first option is used if the heating temperature of the candles should be lower than the glow ignition temperature, and the engine power can be maximum. The second option is used in engines in which the self-cleaning of candles must be started at low temperature loads.

Rating of the best manufacturers of candles for carbureted cars VAZ-2112, 2115 and Niva

Since the Niva and some VAZ models (2101-2107, 2112 and 2115) have a fairly large number of similar parts in their design (only cars with a carburetor are meant), the same spark plugs are quite suitable for them. Consider the best manufacturers of candles for carburettor VAZ 2112, 2115 and Niva:

Bosch W7DTC. When using them, there is a very stable work engine and a slight increase in its power. Fuel is consumed quite a lot.
Brisk LR15TC. Most a budget option of all those on the list. Candles show good results during operation. Fuel consumption is slightly higher when using them compared to other options, however, for its price category this is a pretty good product.
NGK BUR6E. When using them, the engine runs quite stably. Candles are practically non-toxic, made very high quality, so they are resistant to wear. At the maximum open throttle increase engine power.
Champion N9BYC4. Candles in their design contain three side electrodes. They perfectly reduce fuel consumption, are resistant to wear, and slightly increase engine power.

Rating of the best spark plugs for injection cars VAZ-2112, 2115

Most manufacturers list different replacement intervals for their spark plugs. In principle, the VAZ automobile industry is characterized by a general indicator of 25-30 thousand kilometers of car run.

Advice. Of course, if you notice any malfunctions in the operation of your car or the failure of one of the candles with less mileage, then it is advisable to replace this part immediately.

The candles that are installed on the VAZ-2112 and 2115 are almost identical to each other, so we will consider the rating of candles that is common for both car models. They may differ slightly in their composition, appearance etc. But they have the same characteristics. We bring to your attention the five most popular manufacturers of candles for injection VAZ-2112 and 2115:

Champion RC9YC. English candles. There is low fuel consumption, they are distinguished by "endurance" and considerable power when the engine is running at high speeds.
NGK BCPR6ES-11. Differ affordable price and at the same time impressive work: resistant to wear, stabilize the operation of the engine, and are also able to increase its power, provided that throttle valve will be open to the maximum.
Brisk DR15YC. An inexpensive model of Czech-made injector spark plugs is perfect for cars operated mostly in urban areas: thanks to an elongated insulator, the spark plug cores quickly and perfectly self-clean.
Bosch FR7DCU. The manufacturer who has proven himself in the best way. The design of the candles includes a copper central electrode covered with a chromium-nickel sheath - this increases its resistance to corrosion processes and erosion. Bosch candles during tests show not very high, but fairly stable results.
Beru 14FR-7DU. By their design, these candles are very similar to Bosch ones: the core is covered with a nickel shell, which makes the candles also resistant to corrosion and erosive processes. And thanks to the conical skirt, the candles self-clean quite quickly. In addition, candles from Beru differ in one “trick”: they give a spark of high power - the fuel burns very efficiently and maximally.

We have presented to your attention a list of the best manufacturers of spark plugs for cars of the VAZ-2112, 2115 and Niva series. Be sure to pay attention to the appearance of candles when choosing a suitable model. We are sure you can do a good choice. Good luck!

Replacing spark plugs: video

2114 and VAZ 2115 - important element ignition system, on which successful per ICE start. The article discusses cases when it is necessary to change spark plugs (SZ), which spark plugs to put in, and also provides instructions for replacing them with VAZ 2114 and 2115.

[ Hide ]

In what cases is it necessary to replace spark plugs?

Replacement of SZ with VAZ 2115 and VAZ 214 is carried out every 30,000 thousand kilometers. If you do not change the SZ in time and continue to operate the car, then the wear of the electrodes increases sharply, this entails a drop in car power and excessive fuel consumption. It is possible to determine the condition of the candle and the ignition system as a whole based on the appearance of the electrode, by the amount and color of soot on it. Brown soot is considered normal.

With long-term operation, the characteristics of the motor change. If you carefully monitor the operation of the internal combustion engine, then the fuel consumption can draw conclusions about the state of the SZ. Knowledgeable people recommend changing candles on VAZs after 20 thousand kilometers, and in winter even after 15 thousand.

You can judge the need to replace the SZ by their appearance, more precisely by the amount and color of soot, as well as the gap between the electrodes.

In addition, the dryness of the thread should be checked. If there are traces of oil on it, this indicates problems with the tightness of the system.

Summing up, we can give cases when it is necessary to change the SZ:

the car does not start well;
increased fuel consumption;
the engine starts to troit;
motor power drops;
exceeding the recommended mileage for replacement.

What kind of candles to put?

The choice of candles is a responsible matter. The service life of the engine, its power, fuel consumption, and successful launch depend on their quality.

When choosing, the greatest attention should be paid to the central electrode, such indicators as: heat resistance, thermal conductivity and plasticity.

The best products are candles, in which the smallest gap is 0.4-0.8 mm, made of expensive materials: platinum, iridium, palladium coated with silver or gold (video by Avtosferaomsk).

It is important to understand what candles are produced for the VAZ 2114. When choosing a new product, you need to study its characteristics in order to choose,. A large number of SZ manufacturers have appeared on the car market, but there are several leaders whose products are in the greatest demand. SZ must work synchronously, so you need to buy them from the same manufacturer and from the same material.

Of the domestic manufacturers, one can name those produced in the city of Engels. They are installed on VAZs from the factory. The quality of the products corresponds to the price, but there is a marriage, so when buying they need to be checked for serviceability. Products A-17DVRM (1.0) are produced for engines with an injector 8 and A-17DVRM (1.0) - for 16 valves.

From imported products, good Czech ones. They are in demand due to good quality. There are 10 series of these products, which differ in design. They have a gap of 1.1, there is a SZ for 8 valve injection engines- BRISK SUPER FORTE LOR15YC-1 and for 16 valve BRISK SUPER FORTE DOR15YC-1.

Japanese products are always of high quality. These candles are installed on some brands of cars directly at the factory. They have a higher price, but they also have the corresponding quality. When buying, you should beware of fakes, as there are a lot of them. For engines with 8 valves with an injector, DENSO W20TT is suitable, for engines with 16 valves, DENSO W20EPR-U11.

NGK is a leading manufacturer of SZ. They are installed by manufacturers on some brands of foreign cars. A car enthusiast claims that candles serve an average of 25-30 thousand kilometers. For engines with an injector, 16 valves are available spark plugs No. 13 BPR6ES-11.

The process of dismantling and replacing SZ

The procedure for removing and replacing spark plugs must be carried out on a cold engine to avoid burns.

The process itself consists of the following steps:

First you need to open the hood. Then you need to dismantle the protection from the engine, if present.
After removing the decorative trim, you need to remove the protective caps from which are put on the contacts. Remove the caps carefully so as not to damage the wiring.
Places near the NW should be cleaned of dirt so that they do not get into the engine cylinders.
Now, using a candle key, you need to unscrew the SZ from the cylinder head. You can start twisting from any side. First you need to move from dead center, and then you can carefully unscrew the SZ from the socket.
Having unscrewed the old SZ, you need to wipe the thread with a rag.
Before screwing in new products, it is advisable to check the clearance on each of them. For vehicles with an injector, it should be between 1 and 1.13 mm.
Installing SZ - the same simple procedure as twisting, is carried out in the reverse order. New products put on seats old candles. It must be screwed in carefully so as not to damage the threads in the cylinder head or on the product.
Next, you need to put on the tips high voltage wires. In this case, you need to make sure that the wire numbers that are marked on them correspond.
At the final stage, the decorative overlay returns to its place.

After replacing the SZ, it is necessary to observe how the engine works. If it works intermittently, it is possible that one of the SZs is defective. To detect it, you need to sequentially turn off each high-voltage wire. A defective spark plug must be replaced.

At the final stage, the decorative overlay returns to its place.

Issue price

Quality products always cost more. Domestic products are several times cheaper, but the quality leaves much to be desired. Therefore, it is worth buying imported candles, which will last much longer than domestic ones. At the same time, the life of the engine will be extended and fuel consumption will be more economical.

Such a parameter as the gap on the spark plugs of the VAZ 2114 injector 8 valves is extremely important for the correct operation of the car engine.

If it is set incorrectly, the following malfunctions may occur:

the car will often stall;
fuel consumption will increase sharply;
oil stains will appear in the candle well;
the car will not be able to maintain the same engine speed;
the engine will start worse;
candles will run out of their resource faster and fail.

In order to avoid such troubles, you should know exactly what clearance of the VAZ 2114 candles should be. Yes, according to technical advice from the manufacturer, for injection engines, the value of this indicator can normally fluctuate between 1 and 1.15 mm. For conventional engines- between 0.6 and 0.7 mm.

This difference is caused by the fact that in injection cars the voltage supplied to the candle is controlled electronic system, and has a higher voltage and current.

Of course, a spark plug with a gap set for a carburetor engine can also work in an injection engine, but it will quickly fail due to strong overheating (the main sign of this is the white surfaces of the spark plug output contacts).

You should know that if in a car with carbureted engine system installed electronic ignition, then the spark plug gap should be set the same as for injection engines.

If the gap is set more than the specified value, then this can also cause improper engine operation, instability while maintaining speed, as well as flooding the candle itself. It is in order to eliminate such troubles that you need to be able to measure the size of the gap and, if necessary, be able to adjust it.

Gap measurement and correction

Before you start adjusting the clearance value, you must first accurately measure it. To do this, you need a tool such as a probe. They are sold in the form of a set of thin steel plates with a precisely known value, fixed on one axis (like a folding knife).

The gap of the spark plugs VAZ 2114 injector 8 valves is measured according to the following scheme:

Disconnect high voltage wires.
Selecting a feeler gauge with a thickness of exactly 1 mm, insert it into the gap.
If it enters with little effort, but at the same time is slightly clamped between the output electrodes, then the gap is correct.
If the probe passes easily and does not meet resistance, then the gap is large and a larger probe should be taken.
If the measured clearance turned out to be more than 1.15 mm, then it will have to be corrected.
The same applies to the situation when the 1 mm probe does not fit into the gap at all.

If, after measurements, it is found that the electrodes are too far apart, it will be necessary to bring them closer together. To do this, you will have to slightly bend the upper electrode and repeat the measurements again (and so on, until the required gap is reached). If the gap turned out to be small, then the upper electrode, on the contrary, will need to be slightly bent up.

It is important to remember that it is impossible to apply too much force to the candle electrode. It can break off very easily, and then there will be nothing left but to completely replace the candle with a new one.

It should also be noted that the gaps on the candles of the VAZ 2114 injector should be checked even after they are bought in the store. Indeed, sometimes, even candles that have just arrived from the factory already have the wrong clearance.
