Why does the engine do not pull? Causes of power drops. The engine does not pull

According to statistics, every car owner with a long service of the car is experiencing problems with a burden, depending on the reasons, the car or poorly accelerated, or could not even touch the place. In a different way, the engine is simply not enough power to cope with all loads - dial speed and speed.

Dashboard

The most interesting thing is that the motor in such situations behaves like completely "healthy". Do not hear any noise, no knock or other evidence of work violations. I would like to note immediately that the list of possible causes of power loss is huge and to paint all the faults is very difficult. Let us give a list of only the most common, as well as detail their character and possible causes of appearance.

The main causes of power loss

If there are no other problems, as soon as the thrust loss is found, then first of all it is worth paying attention to quality. As practice says, in 51% of cases with power lies, poor-quality fuel is associated. The tank is reflected bad or non-corresponding for this model, fuel. It is not rare that modern cars, especially foreign production, do not tolerate 92 gasoline brand. Sometimes it can cope quite simply, it is enough to dilute with better fuel. Often, such manipulations help with the unstable operation of the engine, "" turns and the like. Then it is simply observed "" on the tidy.

Owners of gasoline engines without problems can check the quality, looking at the candles. If the reason lies in combustion disorders, as well as the presence of impurities - it will be displayed on the candlelight, the nagar will appear, and the color will change.

For example, when the fuel is oversaturated with third-party metal-containing components, the "skirt" and contacts will cover a reddish tint. The formation of black nagar indicates the defective combustion of the mixture. In any situation, with failures in combustion processes, the engine loses power.

Also do not forget that when checking the candles, you need to remember the service life. They are not durable, especially if it was originally not high-quality. Now an interesting fact, if after replacing the entire set of candles, "scale" is formed as quickly and the engine is experiencing the same problems, then the reason is to look for in filters or cylinders.

Problems with gas distribution phases occur due to not correctly installed "Label" belt, timing chains. Belts are stretched, chains are jumping, after which due to ignoring problems, the consequences may be much sad.

Engine banal wear. Do not forget that cars with mileage on average lose 10-15% of power. If the power loss in your opinion is much more, then it is reasonable to check the compression. Weak compression, and this is often less than 10 kg / m. He indicates the struggling walls of the cylinders, the wear of the rings, the valve fixes and the like. Compression data for each model will differ, but usually it is 12-14 kg / m. More about what you have, you can find out in the service book.

Causes in transmission. Worn clutch in the manual transmission or slip of the automatic transmission. The check is better to entrust the experienced masters, especially this concerns the automatic transmission.

Sometimes the owners of the product of the domestic auto industry are faced with the situation when the injection engine does not pull on the VAZ 2114. This problem is not rare, so we will try to carefully understand the reasons for the "weakness" of the engine and solve them yourself.

List of possible causes of power drop

Quickly answer the question: why the drift of the VAZ 2114 engine disappeared on 8 valves can be far from the first time, not everyone, even an experienced, driver.

To do this, you need to consider all possible sources of breakage:

• getting garbage in a gasoline cleaning filter;
• zoom of the fuel pump diaphragm;
• fault of the sensor controlling air flow;
• bad work of candles;
• problem in the work of the ECU (electronic engine control unit);
• dusting air filter;
• zado injectors;
• full wear of the clutch disk;
• insufficient compression in the cylinders.

Analysis of the reasons for bad engine thrust and possible repair

Fuel filter pollution

There may be noble gasoline to this (containing various small garbage) or rare cleaning of the fuel tank. In this case, you will have to completely replace the entire filtering system.

Baszonasosa diaphragm dilution

The cause of the blockage, as a rule, becomes low-quality gasoline. For cleanings, it is enough to get a diaphragm and rinse carefully or blow it with air.

Malfunction of the sensor controlling air flow

This is the most common reason why VAZ 2114 does not pull.

Signs of malfunction:

• too high or low engine speed at idle;
• intermittent engine work at idle;
• violated overclocking dynamics. The car becomes uncontrollable and often "freezes."

Periodically, it is worth checking the operating condition of the air flow meter to avoid spending time and money, conducting the engine diagnostics.

Air filter dusting

The greater the dust filter, the less air goes to the engine, therefore, the thrust decreases. What can be done in this case? Ideally, the filter must be changed to a new one, but if it is impossible, you should remove the filter, catch up and blow to remove large garbage (flies, dry leaves, bugs).

Zado injectors

When the injector slaves are clogged, you will have to go to a hundred for ultrasonic cleaning, or purchase a special cleaning fluid.

Auto mechanics advise to acquire only high-quality equipment for washing the nozzles, such as Wynn's (Vince), Liqui Moly, Carbon Clean.

The procedure itself is quite simple: the cleaning agent must be pouring into the benzobac. But this method can only help if the fuel system is not polluted. The engine with mileage for several hundred thousand kilometers is likely to need a complete replacement of nozzles.

Complete wear of the clutch disk

It is possible to determine the disk wear on the following features:

• the pedal is easily "interpreted", but does not return back;
• the clutch is sinking;
• when the clutch is turned on, tangible vibration arises;
• unable to turn off the clutch.

There is another way to wear wear: if on the fourth gear, try to move from the place and the engine will stall - it means there are no problems with the disk. If the engine continues to work, then probably the clutch disc will have to be changed.

Bad work candles

There are several signs for which the Ignition Candle faults can be determined:

• at idle the engine makes an unpleasant noise;
• a sharp pressure of gas causes failure in power;
• the engine works unevenly;
• increased fuel consumption with a reduction in power;
• candles are flooded with gasoline.

Visual inspection of candles can also help identify a malfunction. If the candle is covered with dark butter, it has a gloss or velvety nagar, then it unequivocally testifies to problems.

Faulty ignition candles must be replaced with new ones.

Insufficient compression in the cylinders

This defect appears due to the high wear of the entire cylinder-piston system. As a result, the car owner notes that oil consumption increases, the combustible mixture is not completely combustible, and the fuel falls into the crankcase. This problem is serious and resolved either by replacing the piston rings, or the maintenance of the engine at the maintenance station.

Failure in the electronic engine control unit (ECU)

Signs of malfunction of the ECU may be several:

• various mechanical damage on it;
• lack of indicators from various system control sensors;
• the lack of gas station control signals, a system of idling machine and other mechanisms under the control of the ECU.

Unfortunately, this device is not refundable in most cases. Even specialists of the service station will simply be replaced by the ECU to a new one, after diagnostics.

Finally

The article lists all possible reasons for which the VAZ 2114 does not pull. It is independently analyzing them and deal with the poor thrust of the engine for each motorist. This will save a significant amount of money compared to the cost of diagnosis in the service center.

In general, the engine can stop pulling in a variety of reasons - this is one of the most common faults, which can have a huge variety of reasons, and below we will look at the most likely, we describe their symptoms and exploring this issue in detail. After all, one day it may occur with each of us that the engine will lose power, not accompanied by any more symptoms. Probably, the engine does not give any explicit signs of any disease, he seemed to be almost completely in order and does not publish any unusual noise and vibrations, but at the same time he simply does not pull as well as it usually does it. And the problem seems to be getting worse every day and worse, though, you probably didn't even notice when the motor first began to pull it worse.

If such a situation is familiar to you, let's consider the following reasons for reducing the drive of the motor:

Embossed fuel

First of all, you need to blame the fuel - remember where you were last refueling - perhaps this is a new gas station or the one with the fuel that you have not previously had a ride experience. It is possible that the fuel is simply turned out to be very poorly (it happens so much that you are still lucky if you just stop pulling the engine - after all, someone is probably the engine will stop starting until the owner will replace completely fuel in the tank).

If you refuel on the refueling, where usually, and nothing causes suspicion, go to local communities in social networks, the autoclub of your region / district or just an urban portal - perhaps the gas station was just a bad fuel delivement.

However, most often, with the loss of travelers, the incompatibility of the engine with such poor-quality fuels has other symptoms - for example, such as engine speed instability, difficulties with launching and some others depending on how much fuel turned out to be bad and from the car model.

But it is most likely to determine the poor quality of gasoline itself, twisting the candle from the engine (this will require a special candle wrench) - in general, candles can often be used as the primary diagnostic method of certain malfunctions in the engine combustion chamber, since they are most closely cooperating With this combustion chamber and at the same time are quick-in. If the fuel contains a large number of metal-based additives, then the contacts of the candle and the "skirts" of the central diode will have a reddish color (as if the red brick was covered with a candle).

Polluted air filter

You may also simply pollute your air filter, and in this case, the elimination of power loss will cost you, perhaps, cheaper than all other options - just replace the air filter - you can buy it yourself, so replace with your own hands.

The problem of the contaminated air filter is that the fuel-air mixture, which enters the combustion chamber of the cylinders of your engine, comes there without a sufficient amount of air, and therefore the fuel is not completely combustible, because for its combustion it is necessary enough oxygen. It turns out a situation similar to a person in a person - he seems to eat enough, and leads a healthy lifestyle, but at certain moments of life (during illness by this runny nose), the scored nasal passages are not allowed to breathe normally.

Polluted or old spark plugs

Spark plugs may well be contaminated or excessively worn out, and in this case, if the motor does not pull due to them, it is also a relatively inexpensive version of troubleshooting - Just clean the candles or replace them. However, it should be borne in mind that periodic pollution and wear of the ignition candles are an abnormal process, and the reason for this lies, most likely, somewhere deeper, or in the ignition candle.

Contaminated fuel filter

Fuel filter, as well as air, can cause engine power loss. And the physics of the process here is similar to the air filter - if in the case of the case the fuel did not completely burn due to a lack of air, then in the case of a contaminated fuel filter, on the contrary, the fuel is given insufficient quantity. In this case, simply.

Mechanical problems with the engine

If all the above methods have not saved, and the engine is also badly pulling the car, then it's time to entrust the work of professionals - to begin in a good car service and perform the diagnostics of the engine work - checking compression (compression degree in combustion chambers), for example, can say a lot about work Engine, including about approaching the limit of its resource and the upcoming expensive repair.

Failure in the fuel system

Such a reason for the drop in the engine's diverance, as a violation of the normal operation of the fuel supply system to cylinders, and here can also be a number of reasons that the motor is not gaining momentum, let's list the main:

• Faulty (contaminated) fuel pump due to, for example, poor-quality fuel or gasoline sucking from the bottom of the tank, where the majority of extraneous particles of dirt are ruined.
• Malfunction of the injector or oxygen sensor.
• Exactness of hoses or fuel supply tubes, where air is suused.

Catalyst or exhaust system clogged

The cause of the reduction of the engine's arbitrariness can also become a contaminated catalytic converter or exhaust system. In both cases, the replacement of the corresponding contaminated component will help. It should be borne in mind that the catalyst, as a rule, is very noticeable due to the content in it in certain amounts of noble metals.

We listed the main and most likely causes of possible engine power loss - it must be remembered that such reasons have an excellent set, and if you failed to install them yourself, it is necessary to go to the car service workshop to trust this work to professionals.

If the machine does not show the former power and craving, you will not receive any pleasure from traveling driving. Yes, even often the consumption of gasoline or diesel fuel is growing, the risk of failure of any aggregates is increasing. The owner of the car intuitively understands that something happens in the design of the vehicle. Therefore, the desire to check the car appears, find the cause of flaw and get specific solutions to the problem. Today we will talk about why the car does not pull, and also what you need to do in such situations where it is first worth watching. If you encountered such a problem suddenly, you should quickly diagnose the main nodes of the machine, determine the problem and eliminate the cause of power loss. If the problem is present for a long time, it's time to call for a hundred and solve this question.

If you ride a long time with most problems that cause thrust loss, you can fully soak the power unit and get the need for expensive repairs. So we strongly recommend immediately to pay attention to the tangible loss of engine power or the real feeling that someone keeps you for the exhaust pipe and does not allow to accelerate. The longer you will think that it will pass with time, the more harm you can drive. This will be the cause of excessively expensive repair ultimately. Consider the main reasons for such a phenomenon.

Stop ride on the handbrake, and the thrust will appear by itself

If you always put the car on the handbrake, but you forget to clean it while driving, get ready for impaired traction. When driving on the handbrake, the feeling is created that the car is very tightly accelerated, too difficult is gaining momentum. The driver immediately sin on the engine, steps on the suspension or gearbox. But he even can't even think that it is enough to lower the manual brake lever so that the problem is solved by itself. Moreover, riding on the handbrake will be enough for a long time to be the following troubles with the machine:

• the rear brake discs (or drums, depending on the design of the car) are too heated;
• heating causes the deformation or excessive wear of these parts with different consequences;
• wear in any case will be very high and the reason for the mandatory replacement of the pads and disk after 100 kilometers of such a trip;
• the drum brake can be opened at all during the movement, reducing the safety of the trip;
• heating and excessive friction can cause the failure of some details of the chassis;
• the brake system can also get other problems that require an instant solution.

These troubles are waiting for you if you just forget to remove the hand brake lever at its original position before moving from the place. If you have a manual gearbox, follow the handle becomes even more difficult. On the machine, it is not enough not to gas from the first second, but to give a car to show readiness for the trip, allow him to touch him at idle. In the event that you regularly leave the hand brake regularly, just stop putting the car well, the handbrake. Leave it on the transfer, choose more or less smooth parking spaces.

Check the most common reasons for reducing traction

Reduced engine power can also be caused by other problems. For example, if you conducted an independent re-equipment of the main nodes and parts of the machine, you can be sure that the thrust will decrease. It is also worth paying attention to the frequency of the service and the quality of the busty busty. If you did not change the oil in the car for several years or several tens of thousands of kilometers, the wear of the engine parts will be simply incredible. You will have to restore the unit, and the loss of thrust means that you have little time for repair and preventive work. The main causes of losses are the following:

• poor fuel - if the gasoline is terrible, it simply does not fade completely and does not give the necessary power;
• low quality and poor engine maintenance frequency, which caused the depreciation of the main parts;
• increased wear of the piston group, poor engine performance and power loss due to natural processes;
• depressurization of one of the cylinders, low compression due to large gaps between the details;
• failure of the electrical system, candles, wires and sensors, refusal to work one or two cylinders;
• the transition to alternative fuels, including gas, which naturally reduces the efficiency of the aggregate;
• setting the wheels of significantly larger diameter than they were installed at the factory and replacing other important parts of the machine;
• perform the overhaul of the engine using analog spare parts.

All this processes cause a reduction in thrust, which is the main indicator that you need something to quickly do. Otherwise you have to search how to sell not a completely working car and how to buy more or less normal money. It is better not to bring before and upon the first appearance of problems with the right to bring the life to your iron horse. Loss of engine power should serve as an indicator that you need to take some action.

Why is it better to solve the problem with a load on a hundred?

Of course, if the bad thrust is connected with a forgotten handbrake or bad fuel, no service will help you. Unless, you need to eliminate the problems of increased wear of brake discs. In other cases, it is better to immediately contact a hundred and not experiment with independent possibilities of repairing repair. So you can restore your car in a short time, you do not have to check the possible theories of breakage. The main benefits of maintenance in this case, professionals will be as follows:

• specialists will find the cause of the problem and will be able to fully restore the normal mode of operation;
• on the service you will recommend changing the habits of driving, so that you will not fall into such a situation;
• all parts of the company will purchase independently, which reduces the risk of acquiring poor-quality details;
• diagnostics will show an accurate node that it is worth recovering that it can often save your money;
• performance will be professional, you will be guaranteed to manage the renovated node.

These are important advantages of car service from specialists, therefore it is better not to neglect them and get the maximum comfort in the operation of your car. Often you will have to overpay for the notable services of professionals, but this overpayment will benefit yourself. After repairing the repair at a good station, you will not have to worry about possible repeated problems with the burden. Nevertheless, the health of the car in most cases depends on the behavior of the driver, from the habits on the road. Because if you constantly have a certain problem in your car, just change the driving style. If you have a domestic car, you can see the following video with a description of possible problems with the loss of car thrust:

Let's sum up

Given the sufficiently complex system of the design of a modern car, the loss of thrust may not be so felt or even not felt at all in daily operation. But this is a serious indicator that it is time to fulfill a certain set of repair work. Therefore, it is better to listen to the car and try to determine its real problems. If the power loss was seen, it is best to immediately go to a hundred and eliminate the problem. Only so you can avoid serious destruction with fairly expensive consequences.

If your car has long been hidden the power, do not think that this is a natural car aging process. It is better to go to the goal and eliminate all possible reasons for this problem. However, loss power can indeed be a natural process. Capital repairs, replacing original parts on analog and other familiar processes for the owner of the car are a real problem for the work of the unit. Tell me, have you come across a sharp loss of power in your car, and how was it decided to deal with this problem?

All other things being equal conditions, any engine gives the specified return characteristics under the condition that the fuel-air mixture should be due to the tautology. That is, mixtures of gasoline (or diesel fuel) with air in the right ratio. Accordingly, in the tank should splash, say, quite clean and with the right cetane number of diesel fuel. Or corresponding to the necessary octane number of gasoline. Otherwise, detonation is possible even with the insertion of the ignition advance.

Similar problems may occur trite due to the scored fuel filter or focused nozzles. But everything is in order. So what are the main causes of losses of thrust?

The easiest way to first check the air filter, which in our conditions it is worth changing more often recommended by the manufacturer of the interval. When the air filter is clogged, the motor control unit automatically reduces the fuel supply, as a result, the engine power drops.

Next, suspicion is usually falling on the spark plugs (although they may not be to blame) and the ignition coil, providing the electrical impulse necessary for ignitution. Problems with them are usually accompanied by the fact that the engine "Troit" without giving the required power.

Does not pull the engine and because of the worn belt timber or leakaged to a pair of teeth chains. Because of this, the cycles of gas distribution are disturbed, the cylinders are filled with a non-optimal mixture and the power falls.

Elderly cars often lose power due to wear cylinder piston group. Worn cylinders do not allow maintaining a given compression without ensuring the proper compression of the fuel and air mixture.

It may not pull and a completely new engine - in a cold season, when a viscous oil is immentable to operating temperature resists the movement of all mechanisms of the motor. This happens in a warm course due to a faulty thermostat.

Negatively affects the power indicators also a faulty release system. Periodically, it needs to be cleaned, removing the nagar. The sleeved pipes of the exhaust gas release system or the scored catalytic converter also reduce the power.

In addition to the overwhelming trouble, a worn joke can play a worn clutch. It will tritely slip when trying to press the gas pedal, however, it can be easily understood on floating turnover when switching transmission.

It may grab the brake system, which is why experienced motorists in the winter usually put a car to the transmission so that the parking brake does not grab off.

Of course, the tire pressure should be regularly monitored: the shredded wheels do not contribute to dynamic acceleration. A worn gearbox, especially automatic, in turn negatively affects return.

However, the reasons may be many, they can complement each other, exacerbating the situation with the burden. For example, a lot of reasons lose the power at the turbocharged engine. The turbocharger is intensively wearing, especially with active drivers. There may be problems with the tightness of turbine and compressor highways. Either just a mechanical turbocharger malfunction ...
