Why did the engine pull harder? Why the engine does not pull and what to do? Causes of poor vehicle traction.

string(10) "error stat" string(10) "error stat"

With long-term operation of the car, sooner or later the time comes when the driver begins to notice that the car “pulls” worse and worse. In other words, the motor does not cope well even with small loads. To overcome them, you have to spin the crankshaft almost to the maximum speed. Other signs also appear: sluggish acceleration from a standstill, difficulties in picking up speed when overtaking, etc. In this case, increased exhaust smoke may be observed, but there are no extraneous noises under the hood during the operation of the power plant - it works smoothly and calmly. So what happened, why is the car not pulling?

When the engine pulls hard uphill...

Causes of power loss common to all types of engines

If there are no other signs of deterioration in engine operation, except for loss of traction, it is worth conducting a comprehensive check, which consists in testing the power unit by the "method of elimination".

Poor quality fuel

In about 50% of cases, the "culprit" of the loss of traction is fuel. Due to its low quality or inappropriate octane number (OC), the engine does not develop power.

You can determine that the wrong fuel is in the car tank by a number of signs:

The engine started getting worse.
There was a detonation. This symptom is most pronounced if the fuel with the required octane rating is diluted with gasoline with a lower octane rating.
When examining spark plugs turned out of the cylinder block (BC), one can see black or reddish (brick) color deposits that are uncharacteristic for serviceable parts, which indicates the presence of unnecessary impurities. The first option suggests that gasoline does not burn completely, the second confirms the presence of additives containing metal.
Inefficient candles. This can be determined during a sharp increase in speed, when the engine does not have a margin for further acceleration. Candles can be clogged due to low-quality fuel or simply exhausted.

Solving the problem is not difficult: low-quality fuel should be drained and the tank filled with suitable fuel with the required octane. Clean the candles from soot, and if their service life has come to an end, replace them with new ones, all at once, complete from one manufacturer. When soot appears, you will again have to deal with the diagnosis of the cylinder-piston group (CPG) and (or) the fuel system.

It is better to refuel at trusted gas stations

Dirty air and fuel filters

If the first of them is clogged and does not pass air well, the mixture will turn out to be excessively rich, that is, there will be a lot of fuel in it, which will cease to burn completely. As a result, the thrust of the engine will drop. If the fuel filter is dirty, the result in terms of the operation of the power unit will be the same, only with the difference that the mixture will become very poor, because there will be little gasoline in it. Premature contamination of the air filter may be caused by the operation of the machine in dusty conditions, and the fuel filter may be caused by poor fuel quality.

Violation of the valve timing

The main parts of the gas distribution mechanism (timing) are the intake and exhaust valves. They are "obliged" to open and close only at the right time so that the fuel mixture enters the cylinders on time and the exhaust gases are removed. This process is called phase distribution. If it is violated, you will see that the power of the engine has disappeared, which will begin to "troit", and sometimes it will not start well.

Causes of violation of the valve timing:

wear, as well as improper installation, displacement of the chain or timing belt (most often this is a jump by one tooth (link));
backlash or deformation of the pulley on the crankshaft;
wear of hydraulic lifters, camshaft and (or) its bed;
burnout or rupture of the BC head gasket;
position sensor malfunction camshaft(DPRV).

Recovery normal operation Timing, it is necessary to set the position of the timing shafts and crankshaft according to the marks. If the chain is worn, replace it. The same applies to the camshaft with bed, hydraulic lifters, gasket and DPRV.

Exhaust resistance

Many consider the only task exhaust system– jamming of loud sound and removal of exhaust gases. However, in modern cars a catalyst is installed that reduces the level of emissions of harmful substances. With severe contamination of this element or its destruction, the passage of gases is difficult. As a result, the motor runs "like strangled."

In Russia, the problem is solved by elementary removal of the catalyst. However, it must be remembered that in some car models, such an operation will require changes in electronics (programming).

Catalyst removal

Violation of the ignition timing

We are talking about the moment of ignition of the combustible mixture. It is this that determines the ignition timing (IG). When it deviates towards increase, the mixture lights up early, towards decrease - late. Both options lead to improper engine operation, incomplete combustion of the mixture, which may be accompanied by pops in the muffler. On injection engines VAZ 2110, 211, 212, 214, 215 (there is also a classic with an injector, for example, VAZ 2107) UOZ is set automatically, on carburetor VAZ 2101-2106, 07, 08, 09 (the last two models can be with an injector) it needs to be set manually.

Signs of a violation of the POP:

difficult start of the engine;
increase in fuel and oil consumption;
drop in pick-up and power of the power unit;
unstable operation of the internal combustion engine at idle;
the car responds badly when you press the gas pedal.

UOZ adjustment on an injection engine

Here everything is controlled by electronics. First you need to make sure that it is functioning properly and that the sensor is working. throttle valve. On the Idling it should be ajar by about 1% (if this is not the case, set up a mechanical drive), the normal voltage at its contacts is 0.45-0.55 V (the auto network should output 13-14.3 V). When you sharply press the gas pedal, the damper should open by 90 ”, and the voltage on the sensor should increase to 4.5 V. If this is not the case, you need to adjust the damper drive and check the sensor (TPPS) for proper operation.

To do this:

take the tester and put it in the voltage measurement position;
disconnect the connector from the sensor - you will see three contacts - one goes to ground, the other to the computer (which one is connected to, determine from the diagram);
start the motor and check the supply voltage - it should be about 5 V;
turn off the engine and switch the tester to the resistance measurement mode;
with the damper closed, between the ground and the contact going to the computer, the device should show 0.8-1.2 kOhm;
with the damper open, the resistance is 2.3-2.7 kOhm.

If the received data does not match the above parameters, the sensor must be replaced. If that doesn't work, check the ECU.

Setting UOZ on carburetor engines

The easiest and most effective way is to use a conventional 12-volt light bulb.

Action algorithm:

Turn the crankshaft pulley until the marks match (on the cover - this is the central risk) using a special spanner wrench. If it is not there, turn on 4th speed and push the car until the marks match.
From the ignition interrupter (distributor), disconnect the thin wire going to the coil and attach a light bulb to it, the second contact of which is connected to ground.
Loosen the nut securing the distributor (usually it is a turnkey on "13").
Turn on the ignition, make sure that the lamp is on, and slowly turn the distributor around its axis until it goes out.
Now turn the distributor again until the light flashes, and immediately tighten the distributor nut.

Malfunctioning spark plugs

The planned replacement of these elements of the ignition system is carried out after 20-30 thousand kilometers. If the candles are platinum, the resource increases to 100 thousand km. However, the situation when candles (most often one of them) fail prematurely is not uncommon.

You can see and hear it for a number of signs:

the engine starts with difficulty, especially in winter;
idling is unstable, the tachometer needle jumps, the engine may stop periodically;
during the operation of the power unit, increased vibration is observed, for example, the gearshift lever is shaking;
weak acceleration dynamics - the car does not develop full power, "stupid";
when you press the accelerator, “dips” are noticeable;
fuel consumption has increased.

When one spark plug fails, experienced drivers say that the engine is "troit", that is, only 3 out of 4 cylinders work.

To find the faulty part, you need:

put on dielectric rubber gloves;
with the engine running, disconnect one by one high voltage wire from each candle;
at the same time, the nature of the operation of the motor should change, the speed should fall, but if this did not happen, then the cylinder does not work - the candle does not form a spark.

It is worth finding out the reason for the poor performance of the part, it is quite possible that it is defective. If other candles subsequently begin to fail, you will have to look for the cause elsewhere - the CPG or the fuel system.

Compression reduction

Often, the reasons for the loss of engine power can be associated with the banal wear of the power unit. Do not forget that a car aged about 100 thousand kilometers begins to lose its power by 10-15%. If you think that the losses are excessive, you need to check the compression. Its nominal value is indicated in the documentation for the machine. For testing, you will need an inexpensive device - a compression gauge, which is a pressure gauge mounted on a hollow tube or connected to a rubber hose equipped with a tip. It is screwed into the cylinder block instead of a candle. Next, disconnect the high voltage wire from the ignition coil. Scroll the crankshaft with a starter and note the highest reading of the compression gauge. The operation must be repeated for each cylinder.

Compression test

A pressure below that specified in the instructions by more than 15% indicates wear on the rings, pistons, cylinder block walls, and valves. To solve the problem, you can bore the BC to the repair size, replace the piston rings, grind (or replace) the valves.

Automatic transmission malfunctions

One of the tasks of the gearbox is to transmit torque to the wheels. And if this process is disturbed, then the engine does not gain momentum. You hit the gas and the acceleration is sluggish. The whole thing may be in the slipping of the automatic transmission.

There are several reasons for this:

low-quality or not what the manufacturer recommends gear oil;
clogged filters;
clogged channels of the valve body;
faulty solenoids (in this case, slippage is observed “hot”);
clutch wear (maximum service life 200-300 thousand km);
problem with the control unit.

Most of the above malfunctions in a garage are difficult to fix. Therefore, you will have to use the services of a specialized technical station.

If the carburetor engine does not pull

Carburetor - mechanical device for cooking combustible mixture from fuel and air. If in this mechanism the proportions of the components are violated, then the engine does not pull.

You need to adjust the carburetor in stages:

Jets. Check their calibration - the air supply part must have a larger diameter than the one through which the fuel enters.
Throttle valve. When you press the gas, it should open completely (if this is not the case, adjust the actuator).
Ignition system. Her contact option was discussed above. For check contactless system, turn on the ignition and look at the voltmeter dashboard- his arrow will approach "12", and in a second it will rise higher. If you don't have a voltmeter, substitute a known-good switch and check the ignition system again.

Regular carburetor

Why there is a loss of power of the injection engine

A feature of this motor is a gasoline pump that works like an electric motor. If it does not work properly, the engine speed will be unstable in all ranges. That is, the fuel will be supplied unevenly, which will lead to a drop in the power of the power unit. The pump may not work well due to a dirty filter - it must be checked and cleaned if necessary. Another reason for power loss injection engine- inefficient operation of nozzles, which become contaminated during operation. It is necessary to carry out diagnostics using a special (even home-made) stand and clean the parts or replace them with new ones. The next reason is the incorrect operation of the electronics. It can be sensors or the ECU itself. In the latter case, it is recommended to install a serviceable unit or go to the service station.

If you have any questions - leave them in the comments below the article. We or our visitors will be happy to answer them.

As a rule, during long-term operation vehicle almost every driver sooner or later notices that the engine pulls poorly. In other words, power unit can hardly cope with loads, there is a loss, the unit needs to be untwisted up to high speed to maintain the usual pace, the car accelerates worse from a standstill, slowly picks up speed, etc.

At the same time, the motor in many cases runs smoothly, does not troit, no, knock or noise during operation. We note right away that there is a fairly wide list of possible reasons why a warm engine does not pull, there is a loss of engine power to cold and / or hot.

In this article, we will talk about why the engine does not pull, and also consider the most common malfunctions that manifest themselves in the form of a loss of traction in the power unit.

The motor does not pull: the main reasons for reducing engine power

So, if no other symptoms, except for the loss of traction, are found, then it is immediately necessary to pay attention to the quality of the fuel, the correct operation of the system, and.

As practice shows, more than half of the cases of reducing the efficiency of internal combustion engines are associated with fuel. The engine does not pull due to the fact that low-quality or unsuitable fuel for this type of engine can be poured into the tank (for example, 92nd gasoline instead of 95th).

In some cases, after refueling, there may also be problems with starting the engine, an engine appears. To solve this problem, it is enough to dilute the available fuel with better quality. Less often, it becomes necessary to completely drain the fuel from the tank, after which an additional flushing of the power system is performed.

Usually, such manipulations are necessary when, in parallel with the loss of traction, an unstable operation of the internal combustion engine is noted, and under load, the engine does not start well, on the panel, etc.

Also, owners of gasoline engines can independently determine the quality of gasoline. To check the candles need to be unscrewed from the engine. Violation of the combustion process fuel-air mixture in the cylinders, as well as the presence of impurities in the fuel can be identified by the soot on the spark plugs and its color.

For example, if there are many third-party metal-containing additives and additives in the fuel, then the skirt and electrodes may be covered with a reddish soot (brick color). Black soot will indicate that the fuel is not burning properly, etc. In any case, failures in the process of combustion of the working mixture lead to the fact that the engine stops pulling.

The next step in the diagnosis becomes. The decrease in the efficiency of these elements is also accompanied by a drop in the power of the power unit.

This is especially noticeable during sharp accelerations, and when the car is already moving at high speed. In other words, the motor does not have "reserve" for further acceleration.

Candles may turn out to be dirty, and it should not be ruled out that their resource has come to an end. To fix this problem, you can make or immediately replace the entire kit with a new one.

At the same time, it is important to take into account that if new candles are correctly selected for a particular engine in terms of glow number and other parameters, but still quickly become dirty, then the cause of the loss of traction is not in them. The formation of soot in this case indicates problems with mixture formation or combustion of the fuel charge in the cylinders.

If everything is in order with the candles, then it is necessary to check the condition of the fuel and air filters. In the first case, insufficient throughput can lead to the fact that the required amount of fuel is not supplied to the cylinders to prepare the so-called "power" mixture.

As a result, the engine loses power, that is, it does not pull under loads. In such a situation, it is enough to replace the indicated filter element. As for the air filter, the problem is similar to the fuel filter, however, in this case, there is a lack of air in the air-fuel mixture.

This leads to the fact that the fuel without a sufficient amount of oxygen burns incompletely. Under such conditions, the engine power naturally falls, carbon deposits form in the combustion chamber, candles become heavily contaminated, etc. To solve the problem, it also needs to be replaced.

Malfunctions of the power supply system, ignition and disturbed mixture formation

If problems with spark plugs and filters can be identified right on the road, then more serious problems related to the power and ignition system, it is much more difficult to diagnose and eliminate on the spot. In cases where the engine does not pick up speed, and jerks and dips are noted when pressing the gas pedal, it is necessary to check and or injector.

Let's focus on the more common electronic injection. In the list of the main malfunctions of modern injection internal combustion engines, there are:

malfunctions, reduced performance or contamination of the fuel pump mesh filter;
malfunctions of injector nozzles;
problems with sensors or ECU;
malfunctions of the ignition system;
air leakage and leakage of fuel lines;

If we talk about the ignition system, in addition to candles, you should also check ignition coils, etc. As for the fuel supply, at the initial stage, the pressure in the fuel rail (rail) should be measured. In parallel, the pressure regulator in the fuel rail is also checked.

Often, on many cars, problems are associated with the fuel pump, which is located in the gas tank, as well as with the specified regulator. To measure the fuel pressure, a pressure gauge is connected to the rail, the values obtained are compared with those recommended for a particular engine. If the pressure is below normal, then both the fuel pump and the pressure regulator may be the culprit.

The task of the regulator is to dump excess fuel into the return line at a time when the pressure is above normal. If the settings are wrong or the regulator itself is leaking or faulty, then the fuel will be dumped into the return line ahead of time. To check this, air is pumped with a compressor or pump, the pressure in the rail increases. If the regulator has worked before the recommended pressure indicator, the element must be adjusted or replaced.

Other causes of reduced engine performance

The condition also has a great influence on the power of the motor. The fact is that in order to protect the environment from harmful emissions during the operation of the internal combustion engine, catalytic converters are installed in the outlet.

During operation, the filter catalyst may be destroyed, the throughput of the exhaust system is reduced. As a result, the engine is "strangled". The check is made by measuring the pressure before and after the catalyst. You can also remove the element and inspect its condition visually.

As a rule, official services offer to replace a worn element, but the price of the spare part is very high. For this reason, on many cars in the CIS, the catalyst is simply knocked out, and the control unit is “cheated” programmatically or in other available ways.

Also, when the engine power is reduced, it is necessary to check separately to exclude the possibility of a valve timing failure. Sometimes there are situations when the belt can jump one tooth, the chain stretches, etc.

In this case, the synchronous operation of the valve mechanism in relation to the cycles of the internal combustion engine may be disrupted. This leads to various failures, unstable operation of the unit and a decrease in power.

We also add that engine wear and certain malfunctions also affect engine power. As a general rule, worn-out used ICEs typically lose about 10% of their advertised power.

If the driver feels that there are more losses, then the engine needs. Low compression in the cylinders can occur as a result of wear of the cylinder walls, piston rings, or incomplete closing, etc.

One way or another, any leaks in the combustion chamber will cause the expanding gases during the combustion of the fuel to break out of the cylinder. This means that the pressure of these gases on the piston will decrease, and the internal combustion engine itself will pull poorly and work unstably.

Finally, we note that also the reason that the car lost in dynamics may not be the engine, but the transmission. In other words, the power unit develops enough power, but it is not fully transmitted to the wheels.

This usually manifests itself in such a way that the engine roars, the speed is high, but the car does not move or acceleration is very slow for low gears. Often such problems are associated with clutch or automatic transmission slippage, as well as wedging brake system. To check the brakes, it is enough to disperse the car on a flat road, then turn on the neutral gear.

If, when coasting, it is noticeable that the car immediately began to slow down, then the problem is obvious, the wheels are slightly blocked. If there are no problems with the brakes, then automatic transmission diagnostics are necessary. It is better to entrust the specified procedure to experienced specialists by delivering the car to the service.

Main reasons

There are a lot of reasons for this phenomenon and in most cases they are associated with a malfunction of the systems and mechanisms of the power plant.

Some of them are trifling and very easy to fix, others require quite a serious repair.

The main problem with the fact that the engine does not pull is not related to troubleshooting, but to finding it.

In some cases, it is very difficult to identify what served to reduce traction, and you have to sort out almost the entire motor.

Therefore, we will try to indicate the main reasons why the car accelerates very “sluggishly”.

Since the engines on different cars have their own design features, then we will consider specific models.

Power drop on the VAZ carburetor engine

To begin with, let's take VAZ cars with a carburetor power system and an 8-valve timing - VAZ-2109, VAZ-2110, VAZ-2114, VAZ-2115.

These cars are equipped with the same power point so the reasons are the same.

Let's go through the topics constituent parts, due to a malfunction of which a drop in dynamics may occur.

In general, the main reason that the engine does not pull is a change in the processes in the combustion chambers - a mismatch in the proportions of the air-fuel mixture, the combustion process is disrupted, the filling of the cylinders and the removal of exhaust gases do not occur as required.

Supply system

Very often, a drop in thrust occurs due to the power system. Structurally carburetor fuel system used on cars from the VAZ-2109 to the VAZ-2115 is very simple and is almost completely mechanical, so it is not particularly difficult to identify the cause.

Power reduction can occur due to:

In addition to the elements responsible for the fuel supply, a drop in power also occurs due to the severe contamination of the air filter element.

Ignition system

This system also takes part in the combustion of the mixture, which means that a failure in its operation can affect power.

AT carbureted engines VAZ-2110 and others, a decrease in traction may occur due to:

Faulty spark plugs or changing them thermal gap;
Excessive wear of the contacts and the central electrode of the distributor;
Loss of voltage in high-voltage wires;
Violations of the ignition timing.

Violations in the power supply and ignition systems most often cause a drop in power, so the check to identify the cause should begin with them.

If the operation of these systems does not raise suspicions, other components of the motor should be diagnosed.

Exhaust system, timing and crankshaft

Loss of traction can also occur due to the exhaust system, although problems with it infrequently occur on carburetor engines.

The main reason here is the reduction in throughput due to the large amount of carbon deposits in the muffler. Because of this, the exhaust gases, not having time to escape from the cylinders, "suffocate" the engine.

The reasons for the drop in thrust are also often the gas distribution mechanism and the cylinder-piston group.

Here, the power reduction is due to:

Violations of the thermal clearance of valves;
Strong soot on the valve seats, or their burning;
Occurrence of rings;
Limit wear of CPG;
Breakdown of the cylinder head gasket.

In general, problems with the timing and CPG cause a drop in power in any engine - carburetor, injection, diesel engines. Therefore, we will not mention these mechanisms further.

VAZ injection engines

In injection engines VAZ-2110, 2112, 2114, 2115, both 8-valve and with 16-valve timing, it is more difficult to identify the cause of a decrease in power due to the more complex design of the main systems.

Supply system

Any injector consists of a mechanical actuator and an electronic control, and both of them can have problems that will lead to a drop in power.

Let's look at the mechanical part first. Here, traction can be affected by:

Strong clogging of the mesh filter on the fuel pump;
Decreased fuel pump performance due to wear;
Pollution of the fine filter;
Fuel rail pressure regulator malfunction;
Injector clogging;
Pollution fuel filter;
Air leak in the manifold.

In general, almost every element of the executive part of the injector can be the culprit in reducing dynamics.

Approximately the same situation is in the electronic component.

The operation of the engine with the injector is controlled electronic unit, which constantly monitors the parameters by means of sensors installed on different systems.

The number of these tracking elements is considerable and the failure of any of them leads to the fact that the ECU incorrectly evaluates the indicators on the basis of which it controls the executive part.

Because of this, the readings of the DPKV are violated, as a result, the operation of the ignition system is disrupted, which leads to a drop in traction.

In injection engines, the exhaust gas system creates this problem more often than on a carbureted car, and all because of the use.

The honeycombs of the element have a small cross section, therefore they clog rather quickly, which leads to the fact that the exhaust gases “crush” the motor.

The main reasons with the engines of other cars

So, on a Mitsubishi Lancer 9 car, most often the problem occurs with the exhaust system. This car uses a dual catalyst, which is relatively quickly clogged with soot.

Therefore, many owners of this car, when power drops, recommend paying attention to this system first of all.

But in the ZMZ-406 and 405 engines, which are equipped with GAZelle and Volga cars, the power drop often occurs due to:

Malfunctions of ignition coils;
Losses in high-voltage wires;
Non-working candles;
Sensor failures (primarily DPKV).

But do not forget about the other elements of the power supply systems, ignition, as well as the timing and CPG mentioned above.

For Ford Focus cars, in general, problems with loss of traction arise due to malfunctions of sensors, as well as elements of the power system - especially the fuel module, which includes both a gasoline pump and a filter, combined into a single design.

The same goes for a car like this. Renault Megane. In this machine, a drop in power can occur due to:

Wear of the cover of the distributor;
Faulty spark plugs and wires high voltage;
Weak throughput of the exhaust system;
Worn out fuel pump and dirty filter elements;
Damaged injector sensors.

In general, first of all, you should look for the cause in the power and ignition systems, and only then move on to the timing and CPG.

If the diesel does not pull

Decrease in traction can also occur in diesel engines. If we consider old cars whose power systems are completely mechanical, then the most common cause is depressurization of the system.

On this topic, you can write a weighty book. However, there are a lot of such written today: anyone who is interested will definitely find it and read it carefully. We will try to identify the main reasons for this disorder.

First, let's remember what an engine needs to run. It is necessary that the correct gasoline-air mixture be created, which should be set on fire in time. Therefore, if it is of poor quality or does not come in the proper quantity, then good traction from the motor cannot be expected. With a low octane number, the engine management system will shift the ignition timing to the latest (and still possible). With insufficient performance of the fuel pump or a clogged filter, the fuel will simply not be enough. The quality of fuel atomization by injectors also affects mixture formation. If they are coked and do not form the correct fuel jet, then the proper composition of the mixture cannot be expected either.

For the correct formation of the mixture, another component is also needed -. What if air filter excessively clogged, the engine management system will see the lack of air and limit the fuel supply, which will definitely reduce power. At the same time, the suction of air not taken into account by the engine control system will also violate all calculations.

Now about the initiators of combustion - spark plugs and coils that provide them with high voltage pulses. If these components are underperforming in at least one of the cylinders, then, lacking power.
The optimal filling of the cylinders with the working mixture and the timely removal of exhaust gases depend on the correct valve timing. Therefore, jumping the timing belt or chain even by one tooth will undoubtedly lead to a drop in power.

To ensure an optimal combustion process, the mixture must be compressed. Therefore, cylinder wear, which reduces, has the most negative effect on engine thrust.
An insufficiently warmed-up engine produces less power, not only because the viscous oil resists movement more strongly, but also because the injection system itself limits the parameters. And the motor can be underheated either temporarily, during periods of extreme cold, or permanently - for example, with a faulty thermostat.
The burnt mixture must be removed in a timely manner, so the effect of the exhaust system on engine power is also significant. If the resistance to the release of gases is high, do not wait for parameters from the engine. Either clogged or jammed pipes in the exhaust system can increase resistance.

What else? In addition to the engine, the car has other reasons to lose initial agility. For example, a slipping clutch is worn out or misadjusted: you press on the pedal, the motor responds, and the car barely crawls ... it can also joke: the most banal option is the parking brake.

If we have missed any reasons, we ask you to supplement the material with your own considerations.

If the car does not show its former power and traction, you will not get any pleasure from driving. Moreover, often the consumption of gasoline or diesel fuel increases, the risk of failure of any units increases. The owner of the car intuitively understands that something is going wrong in the design of the vehicle. Therefore, there is a desire to check the car, find the cause of the flaw and get specific solutions to the problem. Today we will talk about why the car does not pull, as well as what to do in such situations, where you should look first of all. If you encounter such a problem suddenly, you should quickly diagnose the main components of the machine, determine the problem and eliminate the cause of the loss of power. If the problem has been present for a long time, it's time to call on the service station and resolve this issue.

If you drive for a long time with most of the problems that cause loss of traction, you can completely ruin the power unit and get the need for expensive repairs. So we strongly recommend that you immediately pay attention to a noticeable loss of engine power or a real feeling that someone is holding you. exhaust pipe and doesn't let it run. The longer you think that this will pass with time, the more damage you can do to the car. This will also cause excessive expensive repairs in the end. Consider the main reasons for this phenomenon.

Stop riding the handbrake, and traction will appear by itself

If you always put your car on the handbrake but forget to release it while driving, get ready for broken traction. When driving on the handbrake, it seems that the car accelerates very hard, it is too difficult to gain momentum. The driver immediately sins on the engine, presses on the suspension or gearbox. But he cannot even think that it is enough to lower the handbrake lever for the problem to be solved by itself. Moreover, driving on the handbrake for quite a long time will cause the following troubles with the car:

the rear brake discs (or drums, depending on the design of the car) get too hot;
heating sometimes causes deformation or excessive wear of these parts with various consequences;
wear in any case will be very high and will cause the mandatory replacement of the pads and disc after 100 kilometers of such a trip;
the drum brake can even shatter into pieces already in the process of movement, reducing the safety of the trip;
heat and excessive friction can cause some parts of the undercarriage to fail;
the brake system may also receive other problems that require an immediate solution.

These are the troubles that await you if you simply forget to remove the handbrake lever to its original position before moving off. If you have manual box gears, it becomes even more difficult to follow the handbrake. On the machine, it is enough not to step on the gas from the first second, but to let the car show its readiness for the trip, to let it start at idle. In the event that you regularly leave the handbrake pulled, just stop putting the handbrake on the car. Leave it in gear, choose more or less flat parking spots.

Checking the most common causes of reduced traction

Reduced engine power can also be caused by other problems. For example, if you carried out an independent re-equipment of the main components and parts of the machine, you can be sure that the thrust will decrease. It is also worth paying attention to the frequency of service and the quality of the purchased fuel. If you have not changed the oil in the car for several years or several tens of thousands of kilometers, the wear on engine parts will be simply incredible. You will have to restore the unit, and the loss of traction means that you have very little time left for repair and maintenance work. The main causes of traction loss are:

bad fuel - if gasoline is terrible, it simply does not burn out completely and does not give the necessary power;
poor quality and poor frequency of engine maintenance, which caused wear of the main parts;
increased wear of the piston group, poor engine efficiency and loss of power due to natural processes;
depressurization of one of the cylinders, low compression due to large gaps between parts;
failure electrical system, candles, wires and sensors, failure of one or two cylinders;
switching to alternative fuels, including gas, which naturally reduces the efficiency of the unit;
installation of wheels of a significantly larger diameter than those installed at the factory and the replacement of other important parts of the machine;
