No idromic turns of VAZ 2107 Injector. Why is the car VAZ injector immediately start and stalls? And what injector

07.09.2020

In this article we will talk about such an unpleasant problem as the engine stop, as well as bad launch. Consider the main reasons why the engine is stallped at idle and on the go. In addition, let's talk about why the motor does not start on hot, as well as about the solution to each of the problems described above.

Common reasons for which idle is stolen:

1. The most common is - regulator (sensor) idle movewhich is directly related to idle engine speed. Check in it whether the breakdown is quite simple. If the machine does not start when you twist the starter, work the gas pedal, the engine must start. If the turns start to swim immediately after you removed the leg with the pedal - 99% what is the reason in the idle regulator. The decision -, for this, the owners of vases will take at least time.

2. The second probable reason why the engine is stalling at idle - problems with throttle valve. This trouble is treated - banal.

3. If after cleaning the problem is preserved, we assume that the reason for which the motor is stalling at idle turns can be DPDZ (throttle position sensor). The problem is solved by, the procedure is not complicated and actually performing with your own hands.

There are no cases when the engine stalls on the go, as they say so much. Below will be listed the most likely and most often occurring reasons for which it can occur.

Motor stops on the go - reasons

1. Embossed fuel is the first thing that comes to the head of the majority of us, besides, it is necessary to start looking for the cause of the engine stopping on the go. You are "lucky" if it happens immediately after refueling, in this case it is safe to say that the problem is in fuel. Treated with fuel and fuel.

2. Candles. As a rule, suspicion is most often falling, after poor fuel Of course. Here everything is simple - unscrew the candles and check their condition, if necessary.

3. Fuel filter. Procedure scored filter It may be caused by a fuel supply interruption, as a result of which you gasut, and the engine stalls on the go. To troubleshoot a malfunction sufficient.

4. Air filter. All the same as with the fuel, if clogged, then the air does not come, therefore the fuel and air mixture comes out of convexed and the candle is simply poured. In addition, a motor shortage of air will be given, that is, power will fall, and the combustion process of the mixture in the cylinders will not be able to be carried out, in the end the motor will be stuck. To eliminate this malfunction enough to replace air filter.

5. Faulty gas station - the second "suspect". If yours fuel pump Not everything is in order, then the car will behave this way, will stall on the go or the engine will not start at all. The problem is solved by checking the pump, its repair or.

6. Battery. The oxidation of battery terminals or bad contact can lead to engine stop. Check the terminals, if necessary, clean them or replace the battery.

7. If the engine strokes on the move and the generator can also become a reason for the cause. The generator failed does not charge, as a result, the side network of the car is powered exclusively from the battery, and it is not enough for a long time. As a result, you are not suspecting that the car is working on the battery, continue to move until it is completely discharged. Treated - and.

6. In advanced auto, reasons can also be with electronics and various sensors. If not strong in this and all of the above nodes and parts are normal, then it is better to turn to the specialties, and then you can replace the floor with the floor of the press ...

Why the engine stalls on the hot, Does it start a well-hot engine?

1. First possible reason -. During the movement through it, a large number of air passes because of which the carburetor is seriously cooled, at the same time cools and fuel that passes through it. As a result, the temperature of the carburetor is several times lower than the motor temperature. Because of this feature, problems arise, after a long journey you are jamming the engine and makes a short stop, at this time the carburetor begins to heat the hot engine housing. Gasoline Bolnis float chamber of high temperatures They begin to evaporate, filling emptiness - air filter, intake manifold and actually the carburetor itself. Aerial traffic jams are formed, and there is no fuel drop in the float chamber.

The solution to the problem is quite simple - press up to half the gas pedal several times and try running the engine. By this you make a mixture poorer and release excess evaporation. It should be noted that problems with the launch of hot can also be due to a similar problem, only the fault of the fuel pump or fuel line. This, as a rule, happens in the heat when from evaporation in fuel system Or the pump is formed by air traffic jams that prevent the flow of fuel into the carburetor.

2. The second possible reason for the strange behavior of the heated engine - problems with the starter. Make sure that when you try to start the engine, the starter twists, and not just clicks or does not respond at all. If this is the case and one of the above options was confirmed. You need to check the starter. If you are on the road, then checking can be reduced to the elementary test of the starter feed wire or other visual operations. If you got home, make a detailed. In the event of a malfunction or replacement.

3. As an option, the reason when the engine does not start on a hot can be a terrestrial battery due to the above, when the generator did not give charging and the battery completely sat down.

Well, it seems to have missed anything!? Today, all, we hope the article will help, tell you the cause of the breakdown and help in solving your problem if you know other reasons, as well as how to solve them, you can add an article using the form for comments. Thanks for attention.

VAZ 2107 ne. best model Among the cars of their class, if compared with foreign approximate analogs. However, thanks to the low price and the available service, the car has been popular in the entire post-Soviet territory. The car was produced since 1982 until 2014. That is, the oldest model has age for more than 30 years. For such a period of operation, the owner will be able to face all types of faults and explore most of the causes of malfunctions.

After several years of operation of the VAZ 2107, as well as almost identical model 2105 begins to show a new character with changes not for the better. Malfunctions associated with force aggregate and its body kit has different naturebut symptomatic:

the engine periodically stalls;
does not hold stable momentum;
unstable work at idle;
it's hard to start;
insufficient power;
increased fuel consumption.

All faults appear for two reasons: violation of adjustments or wear of parts.

Typically expressed in spontaneous change in engine speed. It is observed while driving and at idle. Most frequent cause Furies of revolutions in injection units VAZ2107 / 2105 is the failure of the DMRV (mass flow sensor).

This device controls the amount of air entering the engine. Based on these data, the ECU regulates the supply of a combustible mixture with the optimal ratio of fuel and air with different engine operation modes. Accordingly, in the absence of this balance, the engine turnover is beginning to depend on the amount of incoming oxygen. That is, breeze breeze - revolutions increased, verse - decreased.

Make sure that the DMRV is defective quite simple. Disconnect the device connector, and the computer will go to emergency mode Work. In this mode, the fuel supply is regulated by the throttle position. If the car began to behave adequately, the DMWR is faulty. You can drive it, but a little power will fall and the fuel consumption will increase.

The failed air flow sensor was not subject to repair, with the exception of its pollution, so you can try to clean it.

Algorithm for cleaning DMVR VAZ2107 / 2105:

Remove the sensor along with the protective casing.

Unscrew two screws and pull out the sensor from the base, without touching the surfaces of the active element (current curved wire).
Casing rinse any dishwashing agent.
Using a cylinder with a cleaner for DMVR or for a carburetor, based on alcohols (without acetone), clean the surfaces gently.
Pour 3-4 times abundantly, the liquid must flock.
Dry the device.
Collect the block in the reverse order.

If the problem is not eliminated, you will have to buy a new device.

Unstable carburetor engine

The nature of unstable revolutions of the VAZ2107 / 2105 engine with carburetors is the same as in an injector, in uncontrolled air supply or fuel into the combustion chamber.

But in this case, the carburetor is responsible for the preparation of a combustible mixture. This is a fully mechanical device that is responsible for the optimal ratio of oxygen fuel for different modes of operation of the power unit.

Despite the fact that the fuel and air inputs are filters, they can work inefficiently, as a rule, due to a long service life exceeding the indicated in the standards. As a result, the jets of the carburetor are clogged with small particles.

Drivers with great experience are not very ceremonially, thrown the carburetor VAZ2107 / 2105 in a bucket with gasoline for a day, then blurred from all sides with compressed air and the carburetor seems to be working fine. This is a normal solution, but flammable. Among the causes of the engine work disorders, which are due to the carburetor breakdown, can be allocated:

displacement of the position of adjusting screws from impact or vibration;
an increase in the diameter of the loop of loans due to wear;
wear an axis of the flap restricting its move;
clogging of jets;
violation of tightness float.

To determine the fault of the VAZ2107 / 2105 carburetor, and it is likely to be comprehensive, start by checking the sealant of the float. To do this, remove it from the top of the carburetor (it needs to be dismantled). If in the gasoline float - throw away the float if the air is to check the water with water to bubbles. Suppose he endured the exam, then it is necessary to check the gap.

Lift the carburetor vertically. The gap between the float chamber and the carburetor wall should be 6.5 mm.

Install the carburetor cover and boot the engine for 30 seconds. Remove the lid. The gasoline level should be exactly the coincidence of the middle of the conical surface of the carburetor housing. If it didn't work out, it should be a little bend an angle of the ice rod.

Over time, air and fuel jets are either clogged or wear out. In the first case, they must be cleared and blow. In the second case, check the bandwidth of the jets with a tank with water installed above the fastened gibera per meter. They are connected by the tube. Below is the measuring flask. Measurements occur in units of SM3 / min. Depending on the labeling of the gibber, the volume of fluid collected in a minute in a measuring flask must be appropriate.

It's much easier after 7-10 years of carburetor's work to buy a set of juses and replace them.

Those who use gas plantsYou should know that the carburetor is not used in goal. Over time, inside dry juices, an oxide is formed, which clogs the fuel holes. Machine on gasoline may not start. It is recommended to periodically use gasoline.

Carburetor adjustment

The carburetor adjustment lies in several actions:

Adjust the position of the float above the method described.
Check and install the "quality" and "quantity" screws in the initial state. Wrap them until you stop and unscrew by 2-3 turns for the "quality" screw and 3-4 for the "quantity" screw.
Connect the tachometer or autotester to the terminal "to" ignition coil, and the second probe to the case.
Create and warm up the engine to a temperature of 90 ° C

Winker "Quality" Set the maximum speed at idle. The supply of gasoline increases when the screw is rotated counterclockwise.
The screw "quantity", set the revolutions more, approximately 80-90 rpm.
We determine the quality screw, whether these revs are maximum, if not, then we repeat the procedure.
If the position of the number of the number of the number does not affect the engine turnover, wrap the quality screw so that the turnover fell to 800-900 rpm.

Such adjustment of the carburetor may not be quite accurate, but does not require special equipment.

If the car is stalled

The engine that suddenly stalls does not only create inconvenience when driving, but also is a security threat to the driver and passengers. There are several reasons.

Blinds at idle:

failure of the idling sensor;
the failure of the throttle sensor;
the outflow of the throttle position sensor.

It stalls on the go:

termination of fuel or air due to a contaminated filter;
fault of the fuel pump;
clogging of carburetor jets;
engine overheating.

The diagnosis of the car, the engine of which stalls in the most unexpected places, it is better to start from checking the idle sensor.

Check its performance simply. Remove the device without removing contacts, or connect them after dismantling. Keep the device in your hands, put your finger on the conical needle and ask the friend to turn on the ignition. If you feel jolts, then install the device back. Idling sensor is working.

If the throttle sensor has failed, the car will not only stall, but it does not start, because the computer will give the team to the maximum fuel release, the candles will sing the motor stalls.

If you are on the road by car VAZ and there was a problem with the throttle sensor, it is easier not to bother and contact the nearest service, but if you reach the garage, you can use the following instructions:

Remove the sensor.
Two mm drill drilled in a circle plastic lid.
Remove the plastic platform of the top contact group.
On the bottom platform, you can read WD-40 or alcohol tracks.
The same with contact group The top cover, but do not fade them, they then eaten the tracks.
Collect in reverse order.
By contour, wake any glue for plastic.

Not enough air

Often the car starts well, it goes on the scene, but only it is necessary to disable the sublicas, the engine stalls. It speaks only about one thing - a shortage of air. Most likely, air jets are clogged. They need to unscrew and clean. Then check, the machine should not blame without a suction.

There is an incredible number of reasons for the poor quality of the car's aggregates with similar symptoms, but only a specialist with a set of professional tools for diagnosis can understand them. But if you feel confident - dare, in car services VAZ are waiting for you.

How to solve this problem? Take about cleaning the throttle damper, especially since it can be done with your own hands. The only nuance - for high-quality cleaning you need to purchase in advance special compositionallowing to productively blow injector and other components of the iron construction

Also inspect the oil collector if it is clogged, it's time to spend it and clean it. Otherwise, very soon the ventilation system of the crankcase will be scored, and the motor will literally fall from the excess gases, which means it will not be able to cope with idle.

If the motor stalls, and then start

The incorrect operation of the car at idle is also possible if the firmware of the electronic control unit is installed, intended for the engine. This happens if the motorist relocates with tuning VAZ-2107. As a result of experiments vehicle It gives excellent dynamics, but when the turnover reaches 1000 per 1 minute, the car is not able to withstand the pace, which thus stalls.

Fortunately, such a breakdown is rarely occurring, more often than the wines instability activity of a number of sensors:

the sensor that is responsible for the mass flow rate of the air flow, it is also called DMRV;
sensor defining and helping Adjust the position of the flap (abbreviated name - DPDZ);
the idling regulator of the car, called RXX.

These sensors are practically not repaired. Therefore, everything that can be done is to replace them with new, if you change them gradually, the procedure is inexpensive.

How to repair the idle regulator

Injector, in fact, you do not need to regulate, because the intellectual onboard control system is responsible for the operation of the machine. The idling regulator built into the injector is the mechanism that opens and turnables the airflow again, and the air itself passes along a specially equipped channel for this.

Unfortunately, to establish the exact breakdown of the idling controller (RXX), based on the readings on the onboard panel, it is difficult - the malfunction signal will not light up. But that immediately becomes clear - this is the instability of rotations or their complete propagation. If the VAZ-2107 instrument panel has a check signal, it is quite possible that everything is rchx. This means that the engine is detonated, and this signal is transmitted to the control unit running from electronics.

How to diagnose the VAZ-2107 injector

Practice shows that if the injector stalls at idle, in 70% of cases of all the fault, it is RXX, so we suggest learning the diagnosis:

Measure the voltage on the block where the regulator works. Normal voltage index - 12 V. If the voltage is less, study the wear of the battery and its charge.
If the voltage is completely absent, you should check the entire mechanism power supply chain and then take up the diagnostics of the ECU.
When the multimeter translated into the resistance mode shows between pairs of conclusions different from 53 ohms, disconnect the RXX and turn the ignition. If the needle is immobilized, it means that the idling sensor broke.

How to fix the injector in VAZ-2107

If the replacement of the sensors did not give results, it is better to go to a hundred. Banal lack of tightness intake manifold Provocates the appearances of the same problem when the car stalls at idle.

Do it yourself examine vacuum hoses, gaskets, sealing rings nozzles, and then plugs that are in the collector, a vacuum amplifier brake pedal. Determine the air seats easily with the use of a special unit, which is called a smoke generator. Do not disagrete gasoline pressure check.

VAZ 2107 is not the best model among the cars of its class, if compared with foreign approximate analogs. However, thanks to the low price and the available service, the car has been popular in the entire post-Soviet territory. The car was produced since 1982 until 2014. That is, the oldest model has age for more than 30 years. For such a period of operation, the owner will be able to face all types of faults and explore most of the causes of malfunctions.

The malfunctions associated with the power unit and its body kit are different, but symptomatic:

the engine periodically stalls;
does not hold stable momentum;
unstable work at idle;
it's hard to start;
insufficient power;
increased fuel consumption.

All faults appear for two reasons: violation of adjustments or wear of parts.

Unstable operation of the injection engine

Typically expressed in spontaneous change in engine speed. It is observed while driving and at idle. The most common cause of "festivities" of revolutions in injection units VAZ 2107/2105 is the failure of DMRV (mass flow sensor).

Make sure that the DMRV is defective quite simple. Disconnect the device connector, and the computer will switch to emergency operation. In this mode, the fuel supply is regulated by the throttle position. If the car began to behave adequately, the DMWR is faulty. You can drive it, but a little power will fall and the fuel consumption will increase.
