Engine 1.6 8 valve on VAZ 2115. Which engine VAZ is better. Causes of engine trimming

Most likely, the cause of the motor trimming is candles. In order to ensure this fact, you should unscrew the candle from the cylinder and carefully examine it. If the engine works correctly, then side electrodeAlso, the insulator will be fairly light. A brown tint is also allowed. Candle in such a state should be fully working. But if the nagar on the candle turned out to be black, then the working it simply cannot. It is either enriched with fuel, or it throws oil.

Due to the car formed on the candle, it may not work at all or work occasionally. Both first and the second option prevents the normal formation of the spark.

The causes of the appearance of nagar on candles may be:

• car engine for a long time on idling Or long warmed up;
• a low compression is observed in the cylinder;
• the gas distribution phases are shifted either violated;
• the injector works incorrectly;
• faulty oxygen sensor.

Next, it is mandatory to pay attention to the body, which is placed the ignition candle itself. He must be completely white color, without black dots and stripes. If still the bands or point are visible on the housing, it suggests that the candle makes itself normally, but it will not work.

But if, after conducting an inspection of the candle case, nothing like that was found, you should check the spark during the scrolling of the starter. For this spark is inserted into the tip of the high-voltage wire and placed on the motor weight. The motor is scrolled by the starter. At this time, it is necessary to see if the spark is spooled between the two candles electrodes. If it is observed by the naked eye and has a pronounced blue color, the candle works correctly.

Inspection of high-voltage ignition wires

If it turned out that the spark plugs are in complete orderThis is most likely, means that the problem is precisely in high-voltage wires. In order to check this theory, it is necessary to consider separately each wire. First of all, you should pay attention to the tip of that wire that is inserted into the ignition candle. It must be completely monophonic and do not have any plaque.

The presence of a third-party scale on it indicates that for a while, this high-voltage wire worked in extreme mode. If it does not fix this problem in time, the wire may subsequently pierces, which will lead to much more serious problems and costs.

If during the operation of the car engine, there are interruptions regularly, and the sound outgoing from exhaust pipe, it looks more like a tractor growl, this suggests that your motor troit. This problem needs to be solved, and promptly.

The main causes of trimming

If you say that you have a troit engine, many will answer - the cylinder does not work. But such an argument is not quite correct, since the cylinder ceases to work properly. However, there may be several reasons for any:

• Compression in the cylinders is too low;
• Ignition Candle faulty or partially does not fulfill its functions;
• The valves are poorly adjacent due to a long lack of adjustment;
• Nozzles contaminated or transfused, therefore need to be replaced;
• The oxygen sensor stopped functioning;
• Candle high-voltage wire received damage;
• The ignition coil is faulty;
• DPKV does not work (crankshaft position sensor);
• Broke off ECU ( the electronic unit control);
• The timing belt flew or just jumped into several links;
• The air filter failed or contaminated.

Some problems literally immediately manifest itself in the form of a pretext of the cylinder, but others can show themselves only after a while. And this is the most unwanted event development scenario.

Primary signs of problems that can inform about the cylinder breakage, such:

1. Vibration increases, since the rhythm of the valves and the remaining rotating parts of the gearbox and the power unit are broken.
2. Fuel consumption increases significantly, because the injection system stopped working properly.
3. From the exhaust pipe comes an unpleasant characteristic smell, which is explained high levels Concentration of harmful impurities and unburned fuel.
4. The power of the power unit decreases noticeably, which negatively affects the dynamics and maneuverability of the car.

If you have noticed that the engine troit, but did not take any measures, it threatens you soon a full way out of the engine, to repair which may be impossible. When Troit Injector 8 valve engine On VAZ 2114, in a non-working cylinder constantly comes fuel. It does not burn, but mixed with butter, then turns into the crankcase. If the process continues for a long time, the oil loses viscosity, ceases to perform the role of lubricant, the parts operate on the limit loads, the metal turns into a chips. There is nothing good in this, let's say frankly.

What to do?

There are a number of events that are recommended when detected that the engine is troit. All will allow you to answer certain questions. Therefore, prepare to highlight a lot of time to your car.

The first thing you want to do is to determine the pretext of the cylinder. He is not alone there. For this you need:

1. Open the hood by running the engine at the same time;
2. Listen and remember the sound that now emits your motor;
3. In turn, remove the wires with the candles. If you remove the high-voltage wire, the sound must change. If, when removing the next high-voltage, the sound did not change, congratulations, you found a defective cylinder.

Now dismantle the problem candle and check it for functionality. To do this, you need a special key intended for removing the spark plugs:

1. Pay attention to the electrode. If it is clean, the whole, but on the head a lot of gary is most likely in the combustion chamber there are a large amount of dust. This speaks about the fault of the air filter in the air supply system;
2. If the GAR is present on the head and the electrode, which is noticeably burned, the mixture comes up poor, the combustion occurs with premature ignition;
3. If the head is in Gary, but the electrode is intact, the mixture was rich, and the ignition was submitted late;
4. Check the presence of spark. If it is, then the problem needs to look next. When there is no spark, it is recommended to replace it with a new one and check the engine performance with a new candle.

If your car with a fairly impressive mileage, to identify the causes of "Troji", it is recommended to perform the following operations:

1. Replace the ignition candles;
2. Remove old high-voltages and change them to new, high-quality. Sometimes banal microcracks on them lead to breakdowns and failure of the entire power unit;
3. Measure compression in a cylinder that does not work. When identifying violations, you may define that the valve or problem in the rings are burned;
4. Perform valve adjustment. In general, this procedure is carried out with a periodicity of 15-20 thousand kilometers in order to prevent;
5. Check if the ignition coil works. A common problem for VAZ 2114. Trying to repair it is not worth it, it is better to immediately change to a new one. It will not be worth a lot of money;
6. Replace Old air filter to a new similar aggregate;
7. Check if the timing belt is installed and functions.

If even these events did not give any result, we advise you to try out a few more effective methods Engine Recovery Recovery:

1. Check the operation of the electronic control unit. When problems are detected, immediately change the old electronic control unit to the new one;
2. Check the functionality of the system responsible for fuel supply. In some cases, you have to get to the nozzles;
3. Analyze the operation of the oxygen sensor. It is subject to repair, but it will be better to immediately replace the device;
4. Make sure the crankshaft position sensor is working. This is determined using the electronic control unit. It will give an error that indicates the presence of a malfunction. When problems with the sensor, there is nothing else, except to change it to a new one.

What to do if troit at idle

There is also a fairly common situation, the causes of which there is a total of three.

1. There were problems with fuel supply. Need to rinse fuel system And clean the nozzles ultrasound.
2. There was a malfunction in the ignition system. In such a situation, it is recommended to change the spark plugs, check the performance of the ignition coil, as well as install a new set of high-voltage wires.
3. Valves are not adjusted properly. You will need to adjust the valves. If the situation requires more cardinal measures, then the valves will have to change.

Situations when the engine troit is found in a huge amount of cars. Model domestic producer AvtoVAZ in the face of VAZ 2114 is no exception. This is not a sentence to your engine. Just need to quickly take appropriate measures.

If you intervene in the work of the unit at the very first signs of "Trojas", you will be able to avoid complex and expensive repairs. But when the situation is started on Samotek and check the node is postponed from day to day for later, get ready to spend huge money soon or look at all new engine To replace the old.

The model of this car was developed in 1994, she should have replaced the VAZ-21099. But due to the complex economic situation, the release of the car VAZ2115 began only in 1996. The release was carried out by small batches and almost all cars went to export. By that time the appearance of the car was modern. Several porto appearance not thought out threshold fairing. Its goal was to reduce aerodynamic resistance, but appearance He reminded the launch of novice tuningists.

In 2001, VAZ-2115 began to be collected on the conveyor. Until 2001 it was almost impossible to buy VAZ2115, the car was very popular, and it was prestigious to ride it.

What changes were made to VAZ2115 compared to VAZ21099 in appearance:

• changed the form of the front and rear bumpers;
• bumpers were painted in body color;
• threshold fairing;
• moldings on the doors;
• changed the shape of the hood;
• the front headlights have become already;
• new rear lights;
• anticarp on the trunk lid;
• alloy wheels;
• form of the front wings;
• trunk lid;

By car salon:

• height adjustable steering column;
• new instrument panel;
• heated seats;
• electric windows front door;
• onboard control system;
• At first small cars manufactured from 1996 to 2001, established carburetor Engine, volume of 1.5 liters. This is the engine that stood on the "eights".
• Since 2001, when production has passed on the factory conveyor, the VAZ2115 car began to install a 1.5 liter engine with a distributed fuel injection.
• Since 2007, installed injector Engine 1.6 liter volume.
• The car was produced until 2012 inclusive.

Technical characteristics of the car VAZ2115 video:

During the development of the automotive industry, 4-cylinder engines were among the most popular. And today they are the most common. It happens that due to a number of reasons, one of the cylinders "turns off", and the unit works on the remaining three. It happens that the Troit engine VAZ-2114 injector (8 valves). What are the reasons for this phenomenon and what to do about it? Let's try to figure out.

Engine characteristics

For cars of this model, an 8-valve motor with an index 2111 was developed. If you compare this unit with others, there are serious differences here. it electronic control and distributed fuel injection. ECU fully takes into account all the basic data required for efficient work. The motor is hardy, powerful, economical.

Power is 78 horses. Volume - 1.5 liters.

For each of the four cylinders there are two valves. They have a diameter of 81 mm. Features of the design of this unit allow you to increase the capacity characteristics up to 120 liters. from. There is also a modified unit with a volume of 1.6 liters and with a capacity of 80 liters. from.

Owners are very satisfied with these motors. They fully justify themselves. However, it happens that the engine troit on the go, and other malfunctions are observed. In most cases, all this can be easily repaired.

How to understand that the motor tried?

Convert it with something very difficult. Even inexperienced motorists will be able to clearly hear this sound. Smooth engine operation turns into intermittent terrible sounds. It is difficult to describe it, but from the muffler instead of the usual hissing will be "busting."

Effects

If the motor VAZ-2114 engine is injector (8 valves), the internal combustion engine immediately loses power. After all, on three cylinders, everything is different. Another typical sign for the VAZ line is vibrations, as well as trembling from the motor compartment. Another symptom of "Diseases" - increased flow Fuel and distinct, rich smell of gasoline from and in gases. And that's not it. It is important to respond in time to the emerging signals, otherwise the car will require serious repairs.

When one cylinder does not function, the fuel mixture is not lit in it, but simply accumulates.

Then it is diluted with butter and goes to the crankcase. The greater the amount of fuel go there, the more liquid oil will be. It will quickly lose its lubricant properties. As a result, there is an elevated wear of the cylinder-piston group, rings and other details. After some time, the engine will need overhaul (VAZ-2114 - the model under consideration).

The reasons

There are a lot of them. There are even such nuances, where and real professionals may not immediately determine the problem. However, we give the statistics of the most frequent reasons.

Trojection can occur due to non-working candles. Also, this phenomenon is observed when the high-voltage wire is pierced, the refusal of the ignition coil, a faulty unit of the ECU. One more out possible causes It is in the intake manifold, the loop of the exhaust valve. When punched laying GBC. This problem also appears. This effect is caused by broken compression rings, the squeak of the piston. Naturally, this is not all the reasons why the VAZ-2114 engine troit injector (8 valves).

Mark the diagnosis yourself

Now that you know the reasons, let's look at how diagnosis is performed. You need to start with the simplest. Let it be a non-working cylinder.

So, the first thing should be launched the engine and open the hood.

Then listen how the engine works, and remember this sound. Now alternately deliver high-voltage will not receive the voltage, and the cylinders will stop working. Listen. Did the sound changed? If not, your problem is a non-working cylinder.

Checking candles

It is important to find out whether the spark is in cylinders. To do this, you will need to unscrew the candle from the non-working cylinder, inspect its electrode. If you have seen Nagar or smokence, then such an element should be replaced. It is possible to clean the candle, but it is not forever, but only for a while I solve the problem.

Now check the candle for the presence of a spark. Connect to it a high-voltage wire and put it with a metal part to the motor body. At the same time, put so that the electrode does not touch the housing. Further inviting assistants. His task is to rotate the starter, and yours is to monitor the candle. If you have sparks when working starter, then you may have problems with wires. It is also due to the non-working coil, the ECU or the crankshaft position sensor. Probably there is a shift of the timing belt, which may be the cause of trimming on the go.

Troit in raw weather

Yes, and this is not a joke. Many owners who have a family of VAZ cars say that recently washed or just in the raw day "Iron horses" begin to trim.

Among the common causes are a liquid that fell into candlestones.

As a result, the candle cease to spark, which means that the cylinder cannot work correctly. But this is not all.

So, various sensors could fail due to the effects of the aggressive medium. Also when washing with devices high pressure Different vulnerable parts could be damaged.

As for the conditions of the external environment, the engine troits in crude weather after a long downtime. The launch of the motor does not occur immediately, but from the fifth six times. The operation of the motor is uneven and unstable to full warm-up. Visual inspection Often the results do not give. The operation of the motor becomes normal after a while to complete cooling or to the next rain. The reason here is partially the same as after car wash.

Dampness, or rather, condensate accumulates under the chassis of the traver. There is an easy way to diagnose this problem. Get the engine in the dark. If you see in your hood lights, you need to replace the wires.

Do not forget about the candles. If the engine in dampness does not want to start, then, most likely, the candles are asked to replace. Perhaps they stopped giving a strong spark. In a raw rainy day, moisture can accumulate in the candlelight, which leads to current leaks. An ignition coil is still to be to blame. The enclosures are cracking, and condensate accumulates.

Cold engine running unstable

Sometimes the brands of VAZ cars are told while cold. But it is necessary to warm them as they begin to work more stable. Here you can also select several simple reasons. Most often, the ECU gives commands to create too rich fuel mixes. If you are otried high voltage wiresThis also leads to a similar effect. Worn parts of the piston group will cause a tension.

Troit when he is heated

It happens differently. While cold, you can watch stable workBut it is worth it to warm up how the engine VAZ-2114 engine is the injector (8 valves). Often it is due to the faulty ECU running by gasket or problems in the ignition coil.

Idle problems

This is a particularly frequent situation. And there is no difference, cold Engine either heated. In this case, the reasons allocate very and very much. This can be something elementary - from the failure of one of the candles to serious problems in piston group. If the item changes easily, then worn cylinders involve serious repairs. VAZ-2114 is no exception.

So, unstable work power aggregates on the idling It may be due to the squeezed valves, the mismatch of the belt marks of the gas distribution mechanism, the valve slotting in the motor. They can also be damaged due to hydraulic impact. Various malfunctions in electronics are also not excluded.

If Troit, and then stalls

Many motorists have come across this challenge. The search for possible causes and faults begins. The computer is tested, everything is checked all that can be, and the result is zero. All the same troit engine and stalls.

In this case, you can check the status of the nozzles. Many after a serious diagnosis, this problem is very easy, simply and inexpensively was solved by cleaning the nozzles and the fuel ramp.

If the reason is difficult to find

It happens. And this is a fairly frequent situation. Can help car diagnostics through computer systems. Such an operation tested all sensors, an electronic engine control unit, and as a result, it will be issued information about where specifically in the VAZ-2114 car faults occurred.

If you encountered this breakdown, you should not panic. Everything can be repaired, and this effect is not fatal. If you can not determine the reason, refer to experienced specialists. But often everything can be detected and eliminated with their own hands.

conclusions

It is important to carefully monitor the condition of the car and its individual nodes. With good care, timely replacement supplies And liquids this machine will not work worse than the Swiss watches. Well, if suddenly the unit will finally fail, you can always purchase and install a new - the price of the engine with a volume of 1.6 liters is about 20 thousand rubles.

So, we found out the main reasons why one of the cylinders in the VAZ-2114 car may not work.
