When using the car, each driver faces faults. Visiting a hundred at the slightest problem will cost a significant amount. But some of the problems can be tried to eliminate themselves.

What it is - troit engine

One of the most common problems is a malfunction failure when the engine is called, troit on the cold.

It manifests itself in sharp twitching - "sobbing" of the motor, reducing the number of revolutions, the appearance of a strong smell of gasoline (the combustion process is broken in the chamber), strong vibrations are felt on the steering wheel.

Even in the case when with the further operation of the engine, all manifestations disappear, go to the path on such a car is dangerous. Try to eliminate the problem independently costs even if there is an injection engine. It is quite possible to find the cause of most problems, however, there are those help with which by the specialist only.

Causes of injuries of the injection engine

The most likely reasons for the turbidity of the injection engine:

• There is no spark in the spark plug.

This is the most difficult case, it can be useful to help a hundred.

But as an option - you can independently try to check all coils, sensors, switches. If the reason in the electronic control unit is not to do without computer diagnostics.

• Faulty nozzle.

It is installed simply: it is necessary to check the presence of a spark in the spark plug, if there is - we turn off all the nozzles in turn, the motor works at the same time.

If, when you disconnect any nozzle, nothing has changed, we change it in places with the following. If after this action the cylinder works in normal mode, continue to search for a fault.

• Balanced of fuel pump.

In this case, "problem" will alternately become all cylinders, not only one of them. An additional symptom of malfunction is the complete ability to start the engine.

Only computer diagnostics and sensible electrician will help.

• Air flow sensor breakage.

Causes of Carburetor Engine Troats

The most likely causes of carburetor engine troops:

• Low quality spark plugs.

It is not worth saving on the candlelight.

It is checked elementary: turn on the engine and sequentially disconnect high-voltage wires.

At the same time, on a faulty candle, the motor will continue to work, on the functional - stalls.

After establishing a broken candle, it must be carefully unscrewed out of the socket and carefully inspect the tip. The tip can be completely flooded with gasoline, which occurs with an excessively enriched mixture or when the candle breaks. Pour candles can for a number of reasons.

If the tip of the candle is completely dry, the reasons may be two: the mixture is very poor in the composition or the reason for the breakdown in another part.

• Damage to high-voltage wires.

It is worth conducting a careful inspection, evaluate the state, determine possible deformations or impaired winding.

The latter is very easy to install: it is necessary to put a car in a dark place when the engine is headed - a bright spark in a violation of the insulating wrapper will be clearly visible in the dark, it simply does not reach the candle. Nothing found - We are looking for further.

• Violation of the tightness of the lid of the traver.

It can be a crack, chip and any other defect, with each of them the work of all cylinders immediately violates.

Reduced pressure in cylinders. The pressure in all cylinders should be equal to approximately. With a significant violation of compression in one of the cylinders, the engine diagnostics is necessary for a service station.

Causes of Diesel Engine

The most likely reasons for the troops of the diesel engine are:

• Reduced or completely absent pressure in the engine.

In this case, insufficient temperature is obtained to ignite diesel fuel.

• Faulty nozzle.

The nozzle serves a sprayed jet of fuel into the cylinders. When breakdown, the jet goes solid, ignition is also broken. If the sprayers themselves are faulty, it is necessary to replace them.

• Disruption of the functional or damage to the fuel pump.

At the same time, the engine trimming occurs.

• Violated sequence of engine assembly or incorrect ignition.

• Violation of the correct location of fuel supply pipes.

• Fault of candles and other parts.

Troubleshooting

• If the ignition candle is fault, you can either consider the formed tag, or change the non-working candle to the new one. Both options are good in their own way, depending on the availability of money or free time. To prevent the formation of a new Nagar, it is possible to periodically check the health of nozzles and valves, prevent the motor overheating and perform other non-hard manipulations.

• Damage to high-voltage wires.

The best solution will be the replacement of spoiled wires, however, if, when checking the winding resistance, it is greater than or equal to 20 kΩ), you can close the damaged area using the isol or clean the oxidized parts.

Fault nozzle. If this is an injection engine, then the existing nozzle may be in disrete to a huge number of reasons, such as the breakage of the power chain or its closure, low-quality fuel for use, breakdown, both the injectors itself and its parts.

Confidence in their forces and the presence of the necessary skills make it possible to eliminate the malfunction independently or ask for help from professional professionals.

• Low pressure.

It is explained by the disorder of the tightness of the exhaust valve or the pitch of the gasket on the head of the cylinder block.

• Malfunction of the distributor cover.

The only way to solve this problem is to replace the damaged cover to the new one.

• Poor quality fuel.

In case of problems with a decrease in fuel quality, it makes sense to resort to high-end fuel (diesel).

Conclusion

If the situation occurs when the engine begins to trim on the cold, it is necessary to inspect the parts of the machine for possible damage, in the absence of the result you can always seek help in a proven service station.
