How often do you wash the throttle of a car (the throttle has been washed for a long time)

How often do you wash the throttle of a car (it takes a long time to wash the throttle)? Generally, the throttle of a car is washed every 20,000 to 40,000 kilometers. Throttle is a controllable valve that controls air to enter the engine. There are two kinds: traditional cable throttle and electronic throttle. After the gas enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, which will be burned to do work. The throttle valve is connected with the air filter and the engine block. The traditional engine throttle control mechanism works through a cable or a pull rod, with one end connected to the throttle pedal and the other end connected to the throttle linkage plate. The electronic throttle mainly uses the throttle position sensor to control the throttle opening according to the energy required by the engine, so as to adjust the intake air.
