The VAZ car family, especially the injector engines of the old generation, are famous for the fact that such a malfunction arises as a trim. Why such an effect arises and how to deal with it, consider in this article.
Causes of malfunction
Motorists are wondering: Why does the engine VAZ 2107 injector? Many injector owners of the VAZ 2107 faced the fact that the engine started to trim. This malfunction is characteristic of the whole family of Lada Motors. What are the causes of this effect and where to look for a malfunction:
- Fuel pump and filter.
- Nozzle.
- Spark plugs and high-voltage wires.
- Air filter.
- Throttle.
- Valve.
- ECU and sensors.
Methods of solution
When the causes of the turbulence of the engine VAZ 2107 of the injection type are determined, you can proceed directly to the analysis of the options for eliminating the problem. Before proceeding, it is necessary to understand that the design features of the motor need to know.
But, Motor 2107 is so simple that even the most inexperienced motorist will understand what's the matter. So, consider how to remove the engine troops of the VAZ 2107 injector.
Fuel pump and filter
The first place to find causes begins with fuel supply. To begin with, it is worth checking the fuel pump for performance and there are no violations in operation. If this element does not apply visible signs of damage, it is recommended to disassemble it and check.
Many experienced motorists advise after the fuel pump, proceed to replacing the filtering element of fuel, since it is precisely that a fuel can be bad for nozzles. The fuel filter, according to the service documentation, it is necessary to change every 30-35 thousand km of mileage.
Injectors
The next place to find a malfunction becomes directly the nozzles themselves. They can be clogged due to the use of poor-quality fuel or faulty in terms of operation, simply speaking - worn.
Elements are checked using a special bench, which not only makes the diagnostics of the state, but also carries out the elements. If there is a damaged or worn item, it is better to replace it with a new element.
Spark plugs and high-voltage wires
The loss of sparks can also lead to a violation of the engine. The next node that must be explored becomes ignition. First of all, it is recommended to diagnose the ignition candles. To do this, you need to pull them from the block head and visually examine the presence of cracks. Next, it is recommended to clean the candles from the accumulated mud.
It is worth noting that it is necessary to pay attention to the state of the contacts of the candles. If they are in oil or have a heat, then the problem is not only in the engine troop.
The next phase of diagnostics becomes a call transk using a multimeter and a gap. In most cases, such a diagnosis shows that the candles are not suitable for further use, and they should be replaced.
Another element of the ignition system, which directly affects the ignition of the air-fuel mixture, are high-voltage wires. From their state will depend as well, and the motor will work economically. Therefore, it is recommended to examine them for damage, and also call a multimeter.
Air filter
The contaminated state of the air filter may lead to the engine that the engine will not receive a sufficient amount of air into the combustion chamber, and accordingly there will be a violation of the formation of an air-fuel mixture. Therefore, it is recommended to inspect the element, and if it is found that it is dirty in obligatory order it must be replaced.
Throttle
The contamination of the throttle valve also prevents the normal air supply to the engine. To diagnose the node, it is necessary to dismantle it. If it is found that dust and other alien items have accumulated on the walls, the details should be cleaned. This requires a special means or liquid for cleaning carburetors. This operation can be performed by any car enthusiast without any problems.
Valve
The boosal valves can cause the engine begins to trim, since the slider is formed between the saddle and the exhaust valve, through which the exhaust gases come back into the combustion chamber than the balance in the air-fuel mixture is broken.
To diagnose the node, you need to dismantle the block head. Often, already burned valves are the first sign of wear of the piston group, and, accordingly, everything leads to overhaul.
ECU and Sensors
Last place where it is worth looking for a malfunction, sensors become. Thus, the failure of one or more measuring elements can cause the effect of the trim. Therefore, the motorist will have to check them manually, since the electronic control unit does not always recognize that the sensor has come out.
The electronic motor control unit may also cause trim. Accumulated errors or damage in the software will violate the operation of the entire system. To diagnose and troubleshoot the fault, it is recommended to refer to the specialists.
Output
The reasons for the turbulent engines of the VAZ 2107 are defined and the main methods of eliminating the malfunction are identified. But, if the motorist is not sure that it is capable of repairing his car on its own, it is better not to risk and turn to professionals.

As soon as the number of operating cylinders in the car decreased, one can feel that the vehicle has become less powerful. Even at idle, a significant vibration appears, while in the engine compartment you can hear a shiver. Among other things, it is easy to notic that gasoline consumption has increased significantly, and bringing the nose to exhaust gases, the smell of fuel is heard.
If you do not pay attention to such a problem in time, as a result, the engine may require overhaul. This action will entail waste not only time, but also significant cash.
Possible causes of malfunction
If there is a troop engine on the VAZ-2107, several reasons can serve this. And in order to eliminate the malfunction, such actions should be performed:
- Determine which one of the cylinders is faulty.
- Check all the candles for performance.
- View all wires, nozzles and valves.
- Check how the air climber works in the carburetor.
- Check the operation of both hot and cold engine.
Detect which one of the cylinders failed is simpler. To do this, during the operation of the engine, you should take over the high-voltage wires. But this can be done only if the engine is troit on the VAZ-2107 (carburetor). The cause of the breakdown to find, of course, will not succeed, but to determine the non-working cylinder will undoubtedly succeed.
As soon as you remove the high-voltage wire, which you need, voltage will stop the candle, and therefore the cylinder will stop working.
The next stage of the work is to check the candle for performance. To begin with, after removing the candle, it needs to be carefully examined. If the candle is clearly visible to Nagar, then most likely, that is why the current does not break through. By the way, many motorists believe that it is enough to simply replace the candle to a new one. But in fact, this way the problem will be eliminated only for a while. It is necessary to find the reason why the candle acquired such an appearance.
To do this, check the availability of a normal spark. A high-voltage wire is put on the candle, after which it is brings with its metal end to the engine case. After that, the starter scrolls several times. If the candle is normal, thanks to this movement there should be a good spark. In the event that the spark did not appear, the following reasons are possible:
- cutting a high-voltage wire or its breakdown;
- the ignition coil does not work;
- the electronic control unit was faulty;
- the crankshaft position sensor is broken;
- the belt shifted to several teeth.
But if the spark was in perfect order, but the motor still troit, the reasons may be such:
- defects or wear rings;
- compression disorder;
- nozzles;
- wrong valve operation.
The cylinder may not work because nozzles came out. Most often, this is due to a long-term ride on fuel is not the highest quality or if "handicraft" devices for cleaning the fuel system.
In addition, the VAZ-2107 engine can also told due to the fact that the nozzles simply were clogged. In order to eliminate this malfunction, they are just enough to clean carefully.
Greetings you friends on the site repair cars VAZ do it yourself. Internal combustion engine is one of the most important and complex vests of the car.
If from time to time it does not produce its maintenance, replacing faulty elements and repairs, then over time, a variety of problems can appear - a reduction in power, an increase in the "appetite" of the engine, the appearance of extraneous noises and vibrations.
At the same time, one of the most common problems is the "Trojection" of the engine. As practice shows, such a problem may occur on any car, both domestic and foreign car.
The main thing for the driver is to be able to diagnose it in a timely manner, to find a malfunction and perform quality repairs.
Basic signs, why troit engine
If you know the basic symptoms of malfunction, then to identify the fact of the Troja will not be difficult. There are several of them:
1. The engine failures are manifested, shocking at idle, as well as strong vibrations that are transmitted to the cabin to the driver and passenger.
Such manifestations are difficult to confuse with something, so you can safely talk about the refusal of one of the cylinders.
The problem is only that such symptoms appear too late when one of the "culprits" finally failed.
2. The electrodes on one of the candles are black, are covered with a naigar or soak. Most motorists produce a substitute for a "faulty" candle, without thinking about the reasons. You can not do it this way.
Candle darkening can be a signal of more serious engine problems that require an operational solution.
3. Changes the sound of the exhaust. As a rule, in the case of engine trimming, the emerging sounds literally shake the car. An experienced motorist immediately notes that something is wrong with the car.
4. Increases "Voracious" cars. There are many reasons for this phenomenon, therefore it is desirable to fully diagnose the power node.
5. The dynamics of the car deteriorates. This is especially noticeable at the time of a set of speed, on small turns.
But again, such a problem may indicate a number of other faults. Consequently, you need a comprehensive diagnosis.
At the same time, the oscillations can be, both very significant (from 900 to 1500 revolutions per minute), and insignificant.
7. There are unpleasant jerks in the process of a speed set and with normal driving on any of the gears.
Reasons and malfunctions of engine trimming
Suppose you really have a troit engine. It is impossible to inactivate in such a situation. On the one hand, a trip to overly "voracious" and constantly twitching auto pleasure will not bring, but on the other - the probability of failure of the rest of the nodes (domino effect) appears.
Therefore, you must clearly know why the motor troit, and what to do about it.
We highlight the main reasons why the engine troit:
- Ignition.
- Vacuum amplifier.
- Spark plug.
- High voltage wires.
- Air filter.
- Piston rings.
- Valve adjustment and their exercise.
- Trim malfunction.
You can diagnose such a problem by passing one of the clocks, the appearance of the sounds of "pats", "bouncing" of the motor.
Listen to the operation of the power node. If the engine troit at idle, and after the start of the movement and the set of revolutions, the problem disappears, then the reason is the earlier ignition.
In this case, it suffices to make simple adjustments that you will take at least time.
2. Damage in the system vacuum brake system amplifier (deterioration of the tightness of the valve or the diaphragm). Such a malfunction can lead to the appearance of air in the system.
As a result, the fuel and air mixture becomes the "poorer" and does not flammify in the engine. There are enough one or two "passes" to the candle of the wet and stopped performing their functions.
The appearance of such a problem exhibits itself in all modes - the engine troit on hot, cold and at idle.
3. The failure of the spark plug. As a rule, in almost half of the cases, this reason is the main one when the trimming appears.
To exclude the problem, it is preferably from time to time to inspect the candles, produce their cleaning and replacement (taking into account the deadlines prescribed in the instruction manual for the car). At the same time, it is advisable to change the entire set.
4. Time high voltage wires - A very rare phenomenon, but it happens. What's happening? If there is damage to one of the wiring, the spark will be made your way before and do not reach your candle.
Diagnose the problem is the easiest in the dark. Get the engine and carefully examine the area from the distribution coil to the candles.
The appearance of a bright spark in the interval between the coil and the engine indicates the test of the insulation of the high-voltage wire or the condenser.
As a temporary measure, the insulation of the damaged area is suited (you can use the usual isolate). In the future, the "culprit" is better replaced.
5. Air filter pollution. There are cases when motorists change the engine oil, but forget to install a new air filter.
As a result, the car begins to "choke." The fuel-air mixture is not enriched with the necessary volume of oxygen, and the candles when fuel supply to the engine simply "pours" by gasoline.
Eliminate this problem will not be difficult - it is enough to install a new filter.
6. Deformation of piston rings is a very rare phenomenon. To exclude this problem from the "Agenda", be sure to compress the compression in the engine cylinders.
7. Violation of the adjustment of the valves (their gap) affects the work of the entire node. As a result, from time to time one of the cylinders does not receive its portion of the fuel and air mixture.
The fault is manifested in all modes - the engine troit on the cold, at idle and even in motion. Another probable reason is rocker wear.
To resolve the problem, you need to remove the GBC and setting the valves as instructed by the instruction manual.
8. The timing of the traver can also cause the advent of the power node.
The weak point of this device are bushings, shafts and bearings of the swivel plate, which have the property to wear out.
To correct the situation, it is necessary to repair or replace the traver.
5. The mark of the valve or piston is a serious problem that can be eliminated only by repairing the engine.
Attention! It is not so easy to determine the movement of the engine, as there are a lot of reasons, the article describes the main, but of course not everything, much depends on the type of engine (injector, carburetor).
The difficulty lies also in the fact that it is very difficult to diagnose the problem - it is necessary to disassemble the power node and inspect the valves and pistons in person.
But note that it is desirable to perform this work after checking (if they did not bring the result) and only if there are appropriate experience.
Remember that the life of the car and its stable work depends on your care.
You need to know if the engine troit is only a symptom that indicates the emergence of a problem in one of the engine mechanisms.
Your task is to find a fault and eliminate it. The faster you do this, the less negative consequences will be for the engine and the cheaper the repair will cost. Good luck on the roads and of course without breakdowns.
Many motorists and owners of 2107 asked themselves - why the engine troit? The effect occurs due to irreversible wear processes of the part of the power unit. But, not everyone knows where to look directly the causes of the malfunction, but even more so the ways to eliminate the problem.
Causes of engine trimming
Why Troit engine VAZ 2107 carburetor and what are the reasons for the manifestation of this effect? In this article we will try to figure out this question as much as possible. Unlike the injector, the reasons will differ, but will be interrelated and similar.
So, let's deal with where to look for the problems of the engine trimming in the carburetor VAZ 2107:
- Piston group.
- Valves and their derivatives.
- Carburetor.
- Ignition system.
- Air filter.
Now, when all the places of origin of the fault are disassembled, it is worth moving directly to the removal methods.
Methods of solution
To eliminate the effect of engine trimming, the motorist will need some structural knowledge of the power unit, as well as hands growing from the right place. To eliminate most reasons, you also need a minimum toolkit.
Piston group
Piston group - a terrible dream of any motorist. The cause of the movement of the engine can be worn out the pistons and oil-chained rings, which in addition to this can damage the walls of the cylinders, forming scratches and sinks on them. In this case, the only way out is overhaul. Of course, this procedure is not pleasant, and not cheap.
Motorist will have to dismantle the cylinder head and pallet. Further, you need to remove the pistons and inspect the walls of the cylinders, if it is developed, then the engine must be dismantled completely, and depending on the degree of damage and wear itching to the desired repair. On the other hand, in case it makes no sense, it is possible to replace the power unit to contract, which may be cheaper overhaul.
Block head
The head of the cylinder block, or rather its components, can become the second reason why the trimming will occur. First of all, it concerns the valves that have already been worn out and easily adjacent to the saddle. As a result, the exhaust gas returns to the combustion stone, and the engine begins to choke.
To solve the problem, it is necessary to replace the graduation and intake valves. For the procedure will have to disassemble the head completely. As practice shows, the valve sleeve guides are also broken and need to be replaced, and therefore floats that the GBC requires a complete overhaul.
Thus, during the work, it will be necessary to replace not only valves, but also saddles, and valve guide sleeves. In order to remove the gap between the valve and the saddle, the second pass the process of the shag.
Carburetor
Another cause of the engine trimming becomes the carburetor. The cause of the cause begins with the fact that it is worth adjusting the supply of the air-fuel mixture. Adjustment is carried out using quality and quantity screws, according to the instructions written in the engine repair and operation of the VAZ 2107 engine.
If the adjustment actions did not help, then the next step is to bulk the carburetor itself. Vaz 2107 engines installed injection elements - Weber and DAAZ (ozone). These two carburetors have the same design, and therefore repair kits are identical to them. Carburetor repair kits can be purchased in stores or on the automotive market.
Ignition system
Another reason for the problem with the engine troops becomes the ignition system, so, when you exit the building, coils or high-voltage wires. If it is easier to speak, then on one or several cylinders there is no spark. To solve the problem, you need to conduct diagnostic operations.
Spark plugs must be unscrewed from the block head and conduct research. First, the parts are inspected visually for cracks, pollution and other faults. You can call the ignition candles contacts with a tester or a special candle stand.
If the product is faulty, it is necessary to change it to a new one, after adjusting the gaps between the contacts. Also, there is an old people's way to check the candles. To do this, the candle is twisted from the cylinder and connects to the high-voltage wire, and then, leaning a candle to the car body, turn the ignition.
As for high-voltage wires, their diagnostics ends with a call to resistance. The working and suitable wire has an indicator of 5 ohms. In case the indicator is higher or lower, it must be changed. Usually it is recommended to replace the wires with a complete set, after checking them on working capacity.
Checking the ignition coil is made using a multimeter for the presence of contact, as well as resistance. In the case of identifying a malfunction, it is necessary to change it to a new product.
Fuel supply
The group of fuel feed parts should include a fuel filter and fuel supply tubes. So, the damaging of these structural parts can lead to an insufficient amount of fuel, which is supplied to the carburetor. To correct the problem, it is necessary to replace the fuel filter and clean the fuel supply system nozzles.
Another element of the fuel system, which affects the stable supply of fuel mixture - fuel pump. When exiting the system, you need to repair or replace the item. After carrying out repair operations, fuel supply must be stabilized, which will break the effect of the trim.
Air filter
Another reason for the emergence of the engine troops of the VAZ 2107 carburetor becomes an air filter, which is due to contamination, not passing a sufficient amount of air to form an air-fuel mixture. To cure the engine, you must replace the replaceable filter element.
Replacing the element of the air filter is quite simple. To do this, it is necessary to get into the open space, that is, to open the hood. Then promotion 3 nuts fastening housing cover and remove the old filter. Install a new shift element and collect all the back.
Output
Determine the reasons - why the troit engine VAZ 2107 carburetor type is quite simple. Start diagnostics stands with elements that participate in the formation of an air-fuel mixture. Then, check the ignition and fuel supply system. Well, the latter, but the most terrible reason can be a major engine repair, due to the wear of the piston group and the head of the block.
