Motor internal combustion is one of the most complex and important vehicle nodes. If it is time not to perform its maintenance, repair and replacement of faulty parts, with time a wide variety of problems may appear - an increase in the "appetite" of the power unit, a reduction in power, the appearance of vibration and extraneous noise. One of the most common problems is the "Trojection" of the motor. As practice is evidenced, a similar problem may appear on any car, regardless of whether the domestic is a model or a foreign car. The main thing for the car owner is to be able to detect it in a timely manner and eliminate it. About this further in the article.

Engine Troy, what it is

The term "Troit Motor" means problems in the operation of one or several engine cylinders. It is believed that the standard power unit has four cylinders. In the conditions of refusal of one of them only three work. As a result, the engine does not pull, which becomes especially noticeable when overclocking. Nowadays, there are engines with three, five, six and even twelve cylinders, so the word "Troit" means that one of the cylinders does not work.

Troit car engine, how to understand what he troit

It is possible to understand that the "engine started Trojourn" by moving the sound of his work. This is especially well audible if you become near the exhaust pipe. Other symptoms accompanying interruptions in the work - an increase in fuel consumption, body vibration, instability at idle speed, power loss (power unit does not pull). Since each of the accompanying symptoms is characteristic of other problems, they are necessary to consider them in the complex.

If the engine is troit, which threatens the car

In this case, there will be a significant drop in power, the car will shake and "tremble", gasoline consumption will be elevated, but all these flowers. In the process of exploitation of such a motor, its resource is rapidly ends for the following reason - when the power unit is operating, the fuel does not burn into the non-working cylinder, which does not burn, and settles on the walls of the cylinder, after which it gets into the oil and car carrier. The fuel begins to gradually dissolve and ignite the lubricant, which, in its turn, loses lubricating properties and, as a result, harms the engine: a drop of compression (there should be no less than ten points in each cylinder), the wear of the rings and pistons (the appearance of scaling), power The unit begins to overheat. Well, then - almost overhaul of the engine.

How to find the cause of the progress of the non-working cylinder, the course of the work of stages

In this case, the check must be started from the definition of a non-working cylinder:

1. We start the motor and open the hood.
2. Carefully listen to the sound of the power unit and remember it.
3. In turn, pull out high-voltage wires.
   
4. When you pull the wires, the corresponding cylinder stops its work, which entails a change in the sound of the motor. Your task is to find that high-voltage wire, while pulling out the sound of the power unit will not change - so you will find a non-working cylinder.

How to check the spark plugs, detailed instructions

Next, we need to determine whether the spark is formed in this cylinder on the candle. With the help of a candle, we unscrew the spark plug and look in what state the electrode:

• Brick color - talks about the correct operation of the cylinder.
• The wiggy, the presence of a small nagar and so on - indicates the incorrect operation of the motor, or it is an excess oil, or the remains of too much fuel.

A similar nagar on the candle prevents its normal work, the spark is created irregular and weak. Replacing the candles or their cleaning in this case will not help, since it is necessary to seek the cause of the car formed. The reason for this may be:

• The outfunction of the final (reverse) valve (if it is clamped - it is necessary to adjust if it burned to change).
  
• In the cylinders, low compression (not less than 10-10-10-10) - correctly measure the compression and make the appropriate repair, most likely you have or burned the valve, or closed the rings.
• The shift of the gas distribution phase - here or incorrectly installed the timing belt, or it jumped - the belt should be dismantled and reinstall with the phase adjustment.
• Incorrect readings of the oxygen sensor - it is necessary to replace it.
• In the fuel system is low pressure.
• Transfix the nozzles - you need to replace.
  
• Also, Nagar may be in conditions of long-term operation of the motor at idle when the candle has a non-standard gallinal number - such a candle is subject to replacement.

In addition, you should pay attention to the white candle body - with the presence of black dots on it or strips, it must be replaced, because the candle breaks.

Electrical safety equipment

When checking the spark plugs, in principle, as with any other works with the electrical equipment of the car, you should be extremely careful and attentive. Watch that the electrode does not touch the engine housing.

How to check the candle to the presence of spark

Now we need to check, gives a candle to the spark or not - a high-voltage wire should be put on the twisted candle, and put the metal body of the candle on the engine. Next, we ask the assistant to start the motor (twist the starter for two to three seconds), and we will see if the spark on the candle at that moment will appear.

Weak spark or its complete absence, what it says about

If the spark appeared, it is necessary to take the candle to one centimeter from the mass and repeat the previous action again. If the spark is clearly visible and it has noticeably weakened, then sparking is bad. The reason for poor sparking or the absence of sparks can serve such malfunctions:

1. Cutting a high-voltage wire or high wire resistance (check the high-voltage wires and replace, they may be incorrectly installed).
2. Malfunction of the electronic control unit (must be replaced or repaired).
3. Fault module ignition (need to be checked and replaced).
4. The crankshaft position sensor fault, the failure of which will say an error that can be seen using a side computer or to diagnose (if the non-working sensor is replaced).
   
5. Again, he could roll off the belt of the gas distribution mechanism on a pair of teeth (we take over and re-set the timing tags).

Troit engine only on cold or hot, for what reasons

Most often, the cause of this problem is valve: adjust the valve gaps is required every twenty thousand kilometers. The fact is that if the engine is troit on the cold, the gap is most likely too big, then the motor heats up and the gap decreases, and the operation of the power unit is normalized. The situation with the engine troops on hot exactly the same, but on the contrary: when the engine is cold - the clearance is normal, and when the hot - the valve is clamped and the motor begins to "trot".

How to check the insulation of wires leading to candles

1. First of all, you need to check the high-voltage wires for visible damage (fractures, cracks, and so on).
2. Look, there is no breakdown. To this end, either in the day in the garage or other dark place you need to start the engine and check the absence of sparks on the surface of the high-voltage wire.
3. Another way to check high-voltage wires - in the dark we take a piece of wire and we clean on both sides. Next, we clic down one end to the mass (that is, the car body), and we spend the other end along the entire length of high-voltage wires - the spark is formed in the breakdown locations.

Diesel engine, reasons for holly turns

• Low compression (i.e. pressure) inside the cylinder.
• The failure failure.
• High pressure fuel pump breakdown, for example, a plunger pair refused.

Property Tips: Checking the injection motor better entrust to professionals

If the engine is troit, you should not postpone repairs in a long box, since the consequences of late repair can be extremely serious, up to the overhaul of the motor. As for the injection engine, it is desirable to trust with specialists.
