What is the reason for the oil in the accelerator?

1, engine throttle oil is a normal phenomenon, as long as it is not too much, there is no problem. Throttle oil mainly comes from engine exhaust gas. During the engine operation, some combustible mixture will escape from the cylinder gap to the crankcase. If these exhaust gases are not discharged into the engine, the pressure will increase, so all engines have exhaust valves to discharge exhaust gases.

2. Because the exhaust gas contains some gasoline, the exhaust pipe is connected with the intake pipe of the engine in order to utilize waste and reduce pollution. During the exhaust process, the exhaust gas will take away part of the engine oil, which will remain in the intake system of the engine. Many cars have this problem, which is normal, so don't worry. As long as there is not much oil in the throttle position and the engine does not burn oil, there is no need for maintenance.

3. There is engine oil in the throttle, which is divided into the intake manifold inside the throttle body and the intake source outside the throttle body. Generally speaking, it is inevitable to allow a small amount of oil to exist. If your car burns oil or the oil quantity is unusually low, it should be taken seriously. If your car burns engine oil, the specific reasons should be analyzed and dealt with in many ways. Usually, the throttle body, that is, the intake manifold, has a large amount of engine oil, and the intake valve seat has a large amount of carbon deposit and colloid, which has proved that your car exhaust valve is damaged and the valve oil seal is aging; If there is a lot of oil outside the throttle body, it means that your car turbocharger has been damaged and needs to be replaced. As for the serious wear of the engine cylinder liner piston, it is another matter. Generally speaking, these factors are the main reasons for burning engine oil. Therefore, in the case of engine burning oil, it is necessary to make a rational analysis and judgment. Advocate deep maintenance and replace repair with nursing; No misdiagnosis, no mistakes.
