The pilot throttle valve leaks oil.

Hello, what you want to ask is whether the oil leakage of the throttle of the guide rail is normal? The pilot throttle valve leaks oil normally. The oil leakage of the throttle valve of the guide is that the exhaust gas of the engine is recovered and discharged into the air intake. Because the exhaust gas contains some gasoline, the exhaust pipe is connected with the intake pipe of the compass engine in order to reduce pollution by waste utilization. During the exhaust process, the exhaust gas will take away part of the engine oil, which will remain in the intake system of the compass engine. There is inevitably oil in the throttle valve, so there is oil leakage in the throttle valve of the compass.
