Great or not to warm the engine in the winter. Do you need to warm the car in winter? Possible problems during the operation of a non-heated engine

The issue of warming the engine with the onset of cold weather is one of the most discussed topics. If with the old situation is understandable (you need to warm the unit before the trip, otherwise the engine to a certain warm-up will work unstable, failures occur, the motor stalls), then everything is not so simple. There is a large number of supporters and opponents of the warm-up of a modern injection engine before starting ride. The fact is that injection motors have become much more technological aggregates, equipped with complex, the materials of the manufacture of parts themselves have changed power aggregateMotor oils were improved, etc.

The engine with an injector after the cold start works quite normal, that is, in fact, you can immediately start moving. At the same time, many drivers still adhere to the opinion that such an engine must be prehered, especially in winter. Others, on the contrary, argue that the modern motor does not need warming. In this article we will talk about whether it is necessary to warm the injection engine, to which temperature you need to warm the engine in the winter, and also how you can raise the temperature of the internal combustion engine before starting and how to facilitate the engine launch in winter.

Engine heating in winter on a modern car

Let's start with the fact that technical manual Operating for the overwhelming majority modern cars Separately, the engine does not need warming up before traveling. Manufacturers pay attention to the fact that motor oil and other techniques are evenly heated in motion high revolutions. In other words, production technology and high-quality technical fluids allow you to start moving in gentle mode without damage to the engine motor.

Note that the main goal of such statements is the desire of manufacturers to convince the car owners in the fact that the engine is not necessary to warm. This is done, first of all, in the please of ecology, and not for the sake of increasing the service life of the power unit. Well known is the fact that any motor is rapidly warming up in motion, and a catalytic neutralizer starts working with increasing temperature. It is quite obvious that warming on idle takes longer, fuel consumption when warming the engine in winter is increased. For these reasons, it is proposed to warm the unit on the go to reduce the toxicity of the exhaust gases as soon as possible.

We add that in many European countries at the legislative levels are enshrined individual standards prohibiting warming or long-term operation of the engine at idle in the residential area, etc. In other words, it is impossible to warm the engine in winter or allow the motor in the summer in idling mode, otherwise the driver can finf. Taking into account the fact that in the CIS territory, the car for a large number of people continues to remain the subject of large material value and environmental standards are not so stringent, high attention is primarily paid to the health of the power unit. It should also be added that the mild climate of Europe with its moderate temperatures cannot be compared with the heavy conditions of operation of the inheritance of DVS into severe frosts, which are relevant for our winters.

Supporters of the harvesting claim that the manufacturer of the car would never point out in the manual that you can go immediately, warming up the motor on the go. The main argument-concern for brand reputation, as well as warranty obligations to the consumer. You can agree with this, but only partially. A generally accepted practice today is a guarantee for a new car, which is, on average, 100-150 thousand km. Run. Note that this indicator is almost any modern engine Without serious breakdowns. In other words, the margin of durability implies such operation without warming, taking into account the observance of a number of additional conditions. In this case, not every driver in the CIS changes its car to the new one after completion. warranty periodAnd not ready to do after 100-150 thousand kilometers. If we take into account all the above, it becomes clear that the laws of physics and the peculiarities of the engine work are not able to seriously affect neither technology nor the most modern oils. If you intend to extend the service life of the power unit, then the motor should be warmed.

How and how much do you need to warm the engine in winter

So, with the need for warming up. The fact is that many mistakenly take the total engine temperature for the temperature of the coolant (it is this indicator that displays the temperature pointer on the instrument panel of civil cars). At the same time, we should not forget that for the inhibition in winter, much more an important indicator is temperature motor oil. On the degree of heating of the oil depends on its fluidity, pumping of software and the effectiveness of the formation of a protective film on the details.

• Since it is well known that in a cold engine, the gaps are increased (the parts during cooling are reduced, and when heated is expanding) and the oil is thick, then it becomes clear that even minimal loads on the engine can lead to the occurrence of defects. In other words, the pressure in the lubrication system may not be enough, the oil film breaks through, dry friction occurs, and other damage to the surfaces of loaded elements appear.

It is also important to know that the temperature of the coolant and the oil temperature in the engine is very different. Coolant heating up to 90 degrees Celsius is accompanied by the fact that the oil warmed up only 40-55 degrees. For this reason, the engine launch in winter in the frost means that the lubricant will warm up much longer compared to the coolant. You can also add that gasoline consumption when driving the engine in winter in motion will be increased at the initial stage compared to fuel consumption when heating on idling.

• Considering the above features, it becomes clear that it is optimal to warm up the car from 5 to 15 minutes at idle (depending on outdoor temperature and certain conditions). For example, on many cars to remove the alpine ice and snow from the windshield will not work until warm air goes from the deflectors, and immediately ride with the early windshield simply unsafe. Of course, some drivers remove the ice using special arrangers or use the scraper, but in this case additional financial costs will be required for auto chemicals, and there is a risk of scratching windshield. Another weighty argument in favor of warm-up can be considered comfort, so immediately get into the simply interior and start moving is not particularly nice.
• After the air ducts began to blow warm air and the temperature arrow began to rise a little with a minimum mark, you can start moving. The engine at idle is inexpedient further, since the motor will warm very slowly. When driving, it is necessary to move smoothly on low transmissions, while not spinning 2-2.5 thousand r / m above the mark. Slow accelerations, as well as unacceptable. It should also not be forgotten that not only the motor, but also the transmission, as well as in warming chassis. According to many specialists, oil in the box almost does not heat up at idle and warms up to operating temperature Only after 20-30 kilometers of run.

If you carry out a sharp change of load modes when driving, then accelerated wear The large number of conjugate parts is exposed. In other words, so far the heat gaps come back to normal, and there will also be a complete disclosure of working fluids, even the average loads on the power unit and other velocities of the vehicle should be avoided. Ignoring these rules leads to increased flow Motor oil, location, appearance of scaling, etc.

Add that besides the engine, hydraulic nodes suffer ( steering Reika from gur), shock absorbers, etc. In the process of heating, such parts and aggregates followed a couple of kilometers to avoid motion on the wells and sharp drives of wheels to a large angle. This statement is valid for rear-wheel drive / all-wheel drive cars, which are equipped with oil gearboxes. Without preheating lubricant, these elements may also quickly fail under load. Finally, add that you need to warm both and the motors with. The fact is that the turbine is a fairly sensitive element to the quality of lubrication. Minimal warming on idle turns for the initial ignition of oil and other technicians also require, after which such aggregates are further warmed on the go.

How to start the engine in winter and relieve cold start

If the car is operated in the climatic zone, where there is a significant seasonal decrease in the temperature or the frost stand almost constantly, then it is worth thinking than to warm the engine in the winter before launching. Use of such decisions as installation preheater The engine, the engine electric heating in winter and other developments in this area make it possible to provide simplicity of launch, increase the efficiency and comfort of operation of gasoline and diesel vehicles under conditions of low temperatures.

We add that if the car is located in the region where the climate is moderate, then it will be enough to know how to keep the heat of the engine in winter without serious improvements. We are talking about . In some cases, there is enough auto tube, the heat insulation of the hood or even the installation of a simple cardboard flap in front of the radiator. Such an approach allows you to accelerate the warm-up after starting and increasing the engine cooling time in winter during the parking lot.

It should be noted that most of the modern auto alarms are equipped with a useful function, which allows you to realize the engine autotypewide in winter. At the same time, even if this option is originally not, you can install. This solution Allows you to start the motor remotely, that is, the car will already be heated at idle by the time the driver intends to travel. Autorun can be configured so that the machine will start, for example, every two hours. This will allow you to prevent strong cooling of the motor during the parking lot, which minimizes the possible cold start problems in severe frosts immediately before the trip itself.

The question of whether it is necessary or not to warm the engine of the car in the winter, in Russia truly Hamletovsky. Most Russian motorists living in harsh winters are confident: heating the motor " iron horse"- The case is archiving, and there is nothing to argue about. But most of the manufacturers of modern cars taking purity ambient, It is argued that the engine warming up the engine before driving is harmful, because during the time spent on this operation, a significant amount falls into the air harmful substances. In the European Union, the transition to new standards of Euro-6 is now carried out (some countries block the adoption of these standards, assuring that they are not yet ready to control emissions so hard), automakers put in a rigid ecological framework. Therefore, the only way out for them is the development of high-tech, environmentally friendly engines, which would not need to be pre-war in the most overwhelmed frost. But the European Union is not Russia, especially with regard to weather conditions, and therefore the engine warming in the winter time - the measure is extremely necessary.

There are three arguments for those who taller for refusing the engine, three: it harms ecology, poorly affects the engine nodes and increases fuel consumption. Consider these arguments carefully. As for ecology, there is no dispute, working at idle the engine really produces exhaust gases to the environment. And if you consider that, for example, in the extreme north, the engines of trucks and special transport are not turned off at all, then the ambient damage is made truly colossal. But this is exceptional cases, most of the motorists spend on the heating of the motor up to 10-15 minutes a maximum. And the degree of pollution of the ecology is not so critical, although if there are tens of thousands of engines in the mornings in such a megalopolis, dozens of thousands of engines are simultaneously warming up, then no benefit of the environment can really go. And the Russians are still lucky that such stringent environmental standards do not apply in the country as in the same EU.

Regarding the fuel consumption, then this argument is largely true: depending on the volume of the engine and the time of its work when heating the consumption of fuel grows on average by 3-7 percent. The numbers seem to be non-critical, but if you consider that it is necessary to warm up the engine at least twice a day - in the morning and in the evening, when you return from work, that is, the reason to think about it. And finally, the third argument "Against" is increased engine wear. It also fairly fair, because the long operation of the motor at idle leads to the fact that the fuel-air mixture is excessively enriched with oxygen, it does not fully burn in the combustion chamber, which is formed on its walls. If such a work happens often, the accumulated on the walls of the combustion chamber of the nagar can provoke the engine breakdown, which will be wrapped with costly repairs. Also from long warming can suffer from gasoline motor (They also formed a NAGA) and nozzles in diesel, which simply encourage themselves over time. It also threatens the way out of the specified details. fuel system Engine.

It would seem that the part of the above arguments against the warm-up should convince those who believe that the engine in the laundry frost is still needed. Indeed, the prospect of the repair of the engine grieves the ordinary Russian motorist much more than pollution of the environment. But at the warming of the engine before driving there is its own arguments "for". And they are pretty weighty. The fact is that the operation of the unheated engine under workloads in winter is fraught with several unpleasant things. First, when the motorist turns the motor in the frost and immediately rides, and it also refers to the engine, the engine is experiencing oil starvation. It is no secret that even the most advanced synthetic oils are changed under the influence of low temperatures their viscosity, becoming curious. What can we talk about semi-synthetic and mineral oils, on which a considerable number of cars goes in Russia. The result of insufficient feed is increased friction of engine parts by each other, which over time leads to the failure of such nodes as cylinders, pistons, the bearings of the camshaft and crankshaft, as well as the details of the turbines. Imagine which amount can repaire repair? That is why many car owners neglect the environment, caring for the safety of motors of their cars, and warm them.

However, there is an optimal means that must reconcile opponents and defenders of the idea of \u200b\u200bhaving warm the power unit. You can do the minimal loss to the environment, the wallet and the motor, if you warm it up not more than 4-5 minutes, and then move, keeping the revolutions not higher than 2000 until the engine temperature is set at a mark of 90 degrees. In addition, so-called so-called, which work autonomously and allow you to warm up not only the motor, but also to establish a comfortable temperature in the car's cabin.

An article about how to warm the car in cold weather - whether to warm up how to do it right, tips and recommendations. At the end of the article - interesting video About whether the engine is frightened or not.

The content of the article:

Winter's offensive is a test for both people and technique. Not all car owners leave their vehicles in garages or on heated parquets, giving preference to street parking or the courtyard territory of their home. From day to day, the declared temperature causes the drivers to reach the cleaning of the car from snow and ice, as well as to careful engine heating.

Young motorists, especially autleden, do not understand why you need to warm the cars for a long time. They are confident that modern models are able to instantly engage in work and refer to the owner on affairs.

However, the negative temperature significantly affects all the mechanisms, increasing the load not only to the engine, but also on the heating and cooling systems.

Also, under the influence of cold, all technical malfunctions immediately appear brightly, which, with standard weather, may not disturb the driver.

That is why the delivery with the car in the winter needs to be studied to not contribute to the accelerated wear of metal elements of the structure.

Modern people love to draw information from the Internet, where it often happens quite contradictory. For example, in the instruction manual of the car, it is written that you can start a trip without prior warming, especially on the street. And in the Scandinavian countries, despite comparable strengths with Russian frosts, and it is prohibited by law to drive the engine in the territory of residential areas at all.

Fuel in a working unit does not exist, filling the pairs of extremely dangerous nitrogen oxides. That is why, as part of an active struggle for the purity of the environment, manufacturers prohibit warming machines.

So what really significant arguments can be brought as the advantage of engine warming before the trip of frosty in the morning?

Motor oil thickness

In the service book to the car, you can find the manufacturer's instructions by the parameters of the oil used in the winter and summer period. For example, mineral oil It is not categorically applicable in the cold period, as it has the property to freeze at -10 degrees.

Semi-synthetic oils have greater resistance to temperature differences, but they are not suitable for too low temperatures.

But the net synthetics can adapt to different temperatures, without losing its qualities neither when the engine is cooled, nor when it is heated. But even it, depending on the degree of frost, thickens on the street, and therefore the first time of the engine does not function as it should. The efficiency of lubrication is reduced, friction of key engine parts increases, causing them accelerated wear.

If allowing oil to warm up, giving the motor to work for some time at idle, it will get rid of excessive viscosity, will again gain fluidity and will be able to effectively distribute the aggregate.

Safety

It is necessary to warm up in winter not only the engine, but also other elements of the automotive construction. On the frost, the windshield and other glasses are also thoroughly freezed and covered with a thin layer of ice.

Many drivers do not like to completely clean the glass, be something dirt from off-road, road dust, snow or ice crust - they wipe themselves a small auditory window and go on the road. It is extremely dangerous for the driver and neighbors by road trafficSince the review with dirty windows is strongly limited and may involuntarily provoke an accident.

Wear of parts and knots

From school lessons of physics, we know that in the cold the items have property to shrink in size. Concerns it and metal parts car Engine, which is slightly, but decrease and in the cold engine work incorrectly.

In order not to contribute to the wear of the elements and minimize the effect of negative temperatures, it takes at least 10 minutes to make the engine at idle.

Fuel consumption

Drivers who follow the fuel consumption of their car will necessarily notice that cold Engine It will consume significantly more. Moreover, it also concerns gasoline, and diesel units, because in the cold the formation of the fuel and air mixture is slower. To ignite it, it is even more effortless to combat viscous fuel and cold air, and for this you need to actively "feed" the engine is combustible.

Battery

Often drivers involuntarily harm car batteryWhen in the cold instead of gradual heating of glasses, quite aggressive electrical heating are started. In this case cool battery It is trying to provide all sources of consumption by the necessary energy, the density of the electrolyte and the battery life itself loses the density.

Surveys conducted by road logs and portals show the following results:

• 38% of car owners necessarily thoroughly warm the car before going in winter;
• 27% do it periodically, with too low temperatures;
• 19% warm the engine is extremely rare;
• 15% do not make it never.

Cars of old designs, carburetor engines It is necessary to warm in obligatory. The fuel and air mixture is formed without the use of electronics, but only by physical processes. Such a car will not be able to move from the spot without heat of a certain temperature, and, in addition, by virtue of its design, it will be bad to carry the load from the temperature difference.

In order to save the most important details and vehicles of the car, you need only 15-20 extra minutes in the morning.

Engine preparation

Faster awaken in the morning the motor will help the short-term inclusion of near light. Then squeeze the clutch, turning off the starter from the transmission and the crankshaft.

Neutral transmission must be turned off, simplifying the engine running on the frosty air.

For a diesel engine, you will need to wait until it stops burning the helix of the heating of candles, which are recommended to use several times for good warm-up.

Running

If from the first attempt, the engine did not start, then it is not necessary to repent of it again and again, the planting battery. After the first time, the battery will need a minute for recovery, after which you can repeat the attempt.

After starting the engine, it is not necessary to immediately turn it on the heating of the glass, then most of the heat formed will go to other needs. Her glass should be heated after heating the rest of the cabin, because if they have the smallest cracks or chips, the flow of warm air will provoke their increase.

Starting

The cold engine will function at high speed - about 1200-1300 revolutions per minute, while in a heated state, this indicator will vary within 1000 revolutions. When the tachometer shows the drop in the rotor of the motor, it will be a signal to the ability to start movement.

Conclusion

Over the past decades, engineers reached excellent results In the field of technologies to protect engines during cold start. In modern cars, the electronics independently prepares the mixture, the motor is quickly and easily started, synthetic oil For the winter period, it is effectively sprinkled and reliably envelops the details of the protective film. Thus, the transmission, and the motor itself is able to actively work even at extremely low temperatures.

But engineers cannot cancel the laws of physics and completely eliminate the elements of the automotive construction from unwanted friction. Therefore, any model is recommended at mandatory to warm up both with severe frost and under cool weather. How much time will be required for each specific machine for heating the key parts and nodes, the car owner will learn to determine on its own.

The elementary ritual will take not much time: to start the engine, warm the interior, glass, smeared the snow, clean the ice and carefully, in a smooth speed will go on the road. But he will relieve the driver from the extra damage, wear of the parts and the accelerated aging of the car.

Extend the operational period of your car and to move as far as possible possible repair Engine - Many car owners seek to this. Regular passing, the application of recommended lubricants - all this positively affects technical condition cars. But there is another moment that causes eternal disputes: engine heating. Opinions are drastically different. Some believe that it is simply necessary to do this, others nag on the instructions for the car and the opinion of manufacturers who do not recommend this. As always, the truth is somewhere in the middle. And yet: Do I need to warm the engine and if so, why and why?

Warming theory

The main material for the manufacture of power units is a metal, expanding with increasing temperature and compressing when cooling. Details power plant Completed taking into account minimization of gaps between them. This reduces energy losses when the mixture is ignited. Until the motor warmed up, the gaps are not as provided for by the automaker, therefore, the DVS is not working in normal mode.

During heating to the operating temperature, the CPG experiences maximum loads. So does it make sense to start moving in such conditions?

Engine Warming: Pluses

They certainly have, and the main one is the restoration of the desired gaps between the parts of the motor, which are provided for by the automaker. But there are other benefits:

• the oil gets the desired viscosity and freely penetrates into all cavities, reducing the friction force, which helps to reduce the wear rate of parts;
• the engine begins to work steadily: traveling with "jerking" can hardly like them;
• fuel consumption on a heated motor less;
• the car warms out inside, and to sit in it in winter it will be much more comfortable.

Cons Warming up

Most chief flaw refers to an environmental problem. For example, environmental pollution by exhaust gases that "issues" a fixed machine with a working engine in Europe is punishable (if you stand more than 5 minutes). The same measures were taken in Russia by the governments of Moscow and St. Petersburg. There are others negative sides:

• extra;
• pollution of catalyst, candles, oils.

Another point: According to automakers, modern cars are prepared for immediate movement.

Features of Wintering Motor Winter

The negative temperature leads to the thickening of the oil, both in the power plant and the checkpoint. This means that at the time of start, the details are not fully lubricated, and the load on the oil pump increases sharply. Of course, there are special lubricants, but they have their own limit.

Another factor is the oxygen content in the air: the lower the temperature, the more. So, the combustible mixture is shifted. On the carburetor motor, this problem can be solved by pulling the subsoil: the damper will be covered, the mixture will enrich. IN injector Engine everything solves electronics exposing early ignition and feeding more fuel to cylinders.

How to warm the motor

You need to start rechargeable batteryTo heat the electrolyte in it. For this 15 seconds. Turn on far light, then turn it off, and wait with half a half. In the presence of mechanical box Slit clutch and then start the engine. If the first time I could not start, wait a couple of minutes to restore the battery, and try again. If it failed, you can go to troubleshooting. When the motor is headed, turn on the stove and direct the air flow on the windshield: this will help to avoid the appearance of possible microcracks between the body and glass.

Warming on the job

The minimum warming time in the parking lot is 5 minutes. During this time, you can, for example, to sleep snow from the body of the car. In this period injector Motor. It warms up and will lift the turnover, and the oil will die and it will be better to lubricate the parts. Further warming can be performed on the go, but it is necessary to follow several rules:

1. Used in the engine must be synthetic and with a large viscosity index. Such a composition confidently fill all channels even in the cold season, which will be guaranteed to "save" from the jackets on the walls of the cylinders.
2. You need to go smoothly, smoothly, slowly, without sharp accelerations and braking. During this time, you just pull out the garage or from the parking lot.
3. Overcoming the first kilometer, avoid bumps and other irregularities on the road.

Do I need to warm the diesel engine

The diesel engine in winter will start much more difficult than the carburetor or injection, which is due to other conditions for the ignition of the mixture. With a negative temperature of the solard, it becomes thick and its spraying on the nozzles is hampered.

The main difference of diesel from gasoline engine It is that its work is possible with the self-ignition of the mixture due to its compression: it increases the temperature to 800-900 degrees. Cooled air prevents heating. Partially help heating the combustion chamber. Another condition for a successful start - the choice of fuel corresponding to the season:

• summer: Recommended temperature from zero and more;
• winter: Up to minus 30 degrees;
• arctic: in demand in the northern regions.

Often difficulties with the launch of the diesel engine arise precisely because of the fuel that does not correspond to the season.

Preparation heaters

Their installation helps to heat the engine faster. And the use of these devices is relevant as for diesel enginesand gasoline. The use of heaters in the northern regions is especially important. The market today offers many solutions: it is only necessary to choose the most optimal option Products.

Improvers associated with warming

1. After the engine warming up to the operating temperature, the car can be used on any modes and maximum power. It is incorrect, because other nodes need in heating: for example, gearbox, gearbox rear bridge (if he is).
2. For faster warm-up, you need to increase the number of revolutions. But this will only lead to more intensive wear of the details of the cylinder-piston group.
3. New car In general, it is not necessary to warm up. Of course, the engine of the machine recently released from the plant will reach the operating temperature faster than the hardened one dozen thousand kilometers by the aggregate. However, it is not recommended to ignore the heating.

Hello, dear friends! Today, on the street in the morning, it turned out to be cold enough, in connection with which I am in a habit of habit, as my grandfather taught me, began to warm the motor at idle. And then there was a thought to consider the question of whether it is necessary to warm the engine in the winter in frost and in the summer before the trip.

Agree, the question is relevant and causes a lot of disputes. Some argue that on modern cars is absolutely no need to warm the power units. Others are confident that regardless of the machine, the engine must be warm up before the trip. And it does not matter, injector it, with a turbine, diesel engine or gasoline. Also does not play the role of the presence of automatic transmission or manual transmission, that is, the machines on the machine and mechanics are in the same conditions.

What do opponents say warming up

There is an opinion of experts and ordinary motorists opposing the need to warm out motors before traveling in winter and summer.

As arguments, they lead the following facts:

• warming the car at idle, you lose ecology, since the mixture becomes too enriched and does not completely burn;
• from the first point it follows another argument - the fuel consumption is growing;
• with the help of modern technologies and materials, including motor and transmission oils, current cars can be operated with the go without warming up;
• the exhaust release system is wearing, the level of pollution of the spark plug and oil is badly heated.

Everything is clear with that. Arguments look quite convincing. But you need to consider the issue fully.

Putting in winter on the wheels, you won't do well our roads. But the priority is the question of your safety.

I will not go into the details of the physicochemical processes that occur in the engine. But you yourself know that at low temperatures, the metal is compressed. Also oils have a certain viscosity. The lower the temperature, the more thick they become. Since the engine and the box are not fraud, the viscous liquid does not fully envelop rubbing parts, unevenly distributed through nodes, which leads to rapid wear and possible breakdowns. Raising turns even higher when you start tall, wear is increased repeatedly.

Even the automakers themselves limit the motor turnover in warm-up mode, which already implies the need for this process before traveling.

What to do in the summer

That is, you already understand that it is possible to warm up the car in the winter and even need. And what to do with the plus temperature? Under such conditions, the oil remains current, it looks like a surface and does not thicken.

We conclude that in the summer I do not need to warm the car? Not. Warming is needed in the summer season. This is necessary for distribution over systems of all working fluids. You do not have to stand and twist the motor at idle 5-15 minutes as in winter. But literally 1-3 minutes to heat the engine up to 40-50 degrees worth it. This is especially true for cars on a machine, that is, with automatic transmission.

Possible problems

The fact that the engine is heated to the operating temperature before replacing the oil, almost everyone who has ever been engaged in a similar question. This allows it to give it fluidity, assemble the sediment from the crankcase and to fully merge.

If the car does not go for some time, or even just stood at night in the garage or in the parking lot, you should warm it before traveling. When you ignore this recommendation, serious problems are possible. And it does not matter, Kia Rio you, BMW or VAZ 2110.

I agree with those who indicate the lack of information on the warming of the motor in the official operating manuals for modern cars. This is relevant for foreign cars. This situation is explained simply. Most imported auto adapted under a relatively temperate temperature, which is rarely lowered in winter below -10 degrees. In Russia, in the winter, a stable the thermometer is overcome -10 and rapidly creeps down. Alas, the corresponding edits in the operating manuals automakers do not.

In fact, if the car does not swing, it leads to certain problems and further breakdowns.

Motor oil

Engine oil and gearbox resembles blood circulating in the human body. Only when the motor turns off, all the lubricant begins to drain into the pallet. The longer the car stands, the less oil remains on the items.

In the spring, summer and autumn, when the air temperature is high enough, to start the motor and distribution of oil through the system, it is enough to 1-2 minutes of warm-up. Try not to trim from the place earlier than 30 seconds after the dvs start.

In winter, the situation is more difficult, because due to downtime, the oil acquires a more dense consistency. Running engine, you must give it time to heat the oil, make it liquid and allow you to spread through the system. It takes more time.

If this is not done, the wear of the gearbox and motor parts will increase, dangerous breakdowns will occur until the need for overhaul.

Oil filter

The filter serves to delay different garbage from the engine and transmission Oil. When the liquid is viscous, it is difficult for it to pass through the filter elements.

If the oil does not pass through the filter, the bypass valve begins to open. In this case, the oil penetrates into the motor without filtering. Accordingly, the metal chips, nagar particles and other garbage finds the engine. It is rapidly contaminated, it begins to work badly, spend a lot of oil and fuel. Nothing good as you understand.

Compression and oiling rings

When the engine does not warm, the likelihood of damage to these rings is increasing, which are located on the ducts of the pistons of the power unit. These rings are needed to remove the surplus oil and create compression. Consequently, they are assigned a serious function.

From the moment of start, a few seconds the motor works at elevated circulation, which then fall. This is due to the progress of cylinders. Warming up the installation, the metal of cylinders will expand, which will free up the rings from compression. Parallel elements of the power unit are better lubricated with oil.

Not warming up the motor and going on the road, you risk sharing rings and damage to cylinders. Repair them is difficult and expensive.

Oil sensor

Many owners of modern cars came across the situation when the oil sensor broke. I will say right away, which basically this is due to the movement on the immentable motor.

Due to the effects of very thick oil, the plastic sensors are simply damaged. And here on-board computer Begins to sign you that there is little oil in the crankcase, although on the fact you just broke the sensor.

I myself relatively recently changed the impact of the car, because I often ignored the recommendations and tried literally immediately after starting.

How much to fight

No one will argue with the fact that heating is simply necessary for the effective, trouble-free and competent operation of the power plant and the entire car.

If the car does not go for a while, even if there are modern 1.8 TSI under the hood, it is not worth the warming up. But the duration depends directly on which temperature overboard.

When the car was plugged a few minutes ago, and you again sit down to the wheel to go somewhere, it is not necessary to warm up it. Motor and so is within operating temperatures.

In the case of long idleness, as shown on the set of rollers in Yutub, warming the engine must be based on the temperature:

With severe frosts, it makes sense to purchase and deliver. But relevant only for regions with the most severe winters.

So why automakers often do not recommend warming the engines on their machines? This is explained extremely simple.
