What is the reason for the engine exhaust pipe injection oil

1. Summary of exhaust The reason for the oil leakage: the valve oil seal is damaged. The valve duct is worn out. The oil san lubricates too much engine oil. The cylinder liner of the diesel engine is seriously worn out. The piston ring of the diesel engine is seriously worn out. The tensile failure of the piston ring of the diesel engine. The seal of the diesel turbocharger is seriously worn out.

2. Reasons for the injection engine oil from the exhaust pipe of the diesel engine: the power is naturally worn, and the gap between the piston ring and the cylinder liner is too large; excessive engine oil affects the pressure of the engine compartment; the failure of the piston pin and cylinder liner;There is severe wear or poor sealing between the valve rod and the valve duct.

3. It is likely that the crankshaft ventilation valve is aging. It is recommended that users replace the crankshaft ventilation valve. Secondly, it may also be because the wear between the valve rod and the valve duct is relatively serious, resulting in an excessive gap, resulting in the situation of oil.

What is the problem with diesel engine exhaust pipe injection oil

There are four reasons for diesel engine exhaust pipe injection: natural power wear, resulting in excessive gap between the piston ring and cylinder liner. Too much oil affects the excessive pressure of the engine compartment. The piston pin and cylinder liner failed. The valve rod and valve duct are seriously worn or poorly sealed. A diesel engine is an engine that uses burning diesel to release energy.

The reason for injecting oil in the exhaust pipe of the diesel engine: the power is naturally worn, and the gap between the piston ring and the cylinder liner is too large. The excessive amount of engine oil causes excessive pressure in the engine compartment. The piston pin and cylinder liner failed. The valve rod and the valve duct are seriously worn or sealed too poorly.

The reason why the diesel engine exhaust pipe injects oil: 1. The valve oil seal is damaged.The solution is to check and replace the valve oil seal; the valve catheter is worn. The solution is to check and replace the valve duct; there is too much engine oil in the oil shell (excessive addition, residual fuel inflow, etc.).

It may be the gas in the cylinder. Maybe the crankcase respirator is blocked. If the exhaust pipe of the car is connected to the upper part, the valve oil seal should be considered. Generally speaking, the exhaust pipe drains oil because of the high pressure of the crankshaft. If it has just been repaired, the organic oil will be stored in the cylinder, and the oil will be discharged in a short time.

The supercharger is damaged, causing the intake pipe to inhale a large amount of oil. The multi-cylinder valve oil seal is damaged, and a large amount of oil enters. The cylinder head oil channel broke, and a large amount of oil entered. Note: A small amount of oil will be burned when it enters the combustion chamber, but the exhaust pipe will have blue smoke. Check that the exhaust pipe is not smooth.If it doesn't work, clean or replace it.

The exhaust pipe injection oil is likely to be due to the failure of the piston, cylinder liner, piston pin and piston ring. At this time, it is necessary to find the damaged position and then replace it. Don't wait until there is a breakdown to pay attention to it. The consequences can be said to be unimaginable.

What's wrong with the oil injection of the Audi A6 exhaust pipe?

1. Some engine oil pressure is too high, which may also cause the exhaust pipe to discharge the oil. There are some obstacles in the exhaust pipe in the engine interface. If the barrier is damaged, it may also cause the exhaust pipe to spray oil. If your car's exhaust pipe leaks oil, you can't ignore it. If it is serious, it will lead to cylinder pulling, engine tearing, and even engine scrapping.

2. I. The return oil back pressure of the supercharger lubricant is too high. Check whether the supercharger is leaking oil and whether the return oil pipe is blocked. II. The exhaust valve is damaged, and the oil and gas cannot be separated, and it re-enters the combustion chamber for combustion. III The valve oil seal is aging, damaged or damaged, and the gap between the valve and the catheter is too large.

3. The fuel injection of the car exhaust pipe is due to the poor combustion of gasoline. Maybe it's because of the wrong oil, or maybe there's something wrong with the igniter, which needs to be dealt with in time. If it is a gasoline electric injection vehicle, it must be caused by the excessive gap in the cylinder wall, and the combustion of the car is not good, so the fuel consumption will be very high.

4. The oil in the exhaust pipe of the automobile may be caused by three reasons: the oil seal at the inlet end is not tightly sealed after it is worn, and the oil will be discharged into the exhaust pipe after burning into the combustion chamber. LiveThe position of the plug ring loses its elasticity or breaks, the cylinder liner is seriously worn, and the oil flows into the combustion chamber to burn and discharges into the exhaust pipe.

What is the reason for the engine's blue smoke exhaust pipe injection oil

1. The reason for the engine exhaust pipe's blue smoke is the burning engine oil, indicating that the engine oil cannot be fully burned when it enters the cylinder combustion chamber and will become blue. Smoke spewed out of the exhaust pipe. Blue smoke is a serious oil burning phenomenon. After this situation occurs, the cause of oil burning should be checked immediately and repaired.

2. Only for vehicles with turbochargers. If a mass of blue smoke suddenly appears while the vehicle is driving, it may be that the oil seal of the turbocharger is damaged, or the turbocharger shell is damaged. Both cases will cause the oil to enter the exhaust pipe directly.The turbocharger will be damaged due to insufficient lubrication or its own quality problems.

3. Participate in combustion with the mixture. The main reason is that the cylinder leaks due to the damage of the piston ring, and the oil enters the combustion chamber. It is recommended to maintain it as soon as possible. In the long run, not only will the engine consumption loss be large, but also the impurities generated by oil combustion will cause an increase in the carbon accumulation in the combustion chamber, which will affect the performance of the engine.
