Causes of dirty throttle

Because of the ventilation function of engine crankcase and the function of activated carbon canister solenoid valve, a small amount of gasoline vapor will be brought to the throttle, and the oil and gasoline attached to the throttle will continue to attach to dust. How long the throttle will be dirty depends on the quality of air filter, engine oil, road conditions, temperature, engine working temperature, driving habits and so on. Dirty oil, long-term non-replacement of air filter and poor quality of air filter will aggravate the dirtiness of throttle valve.
