Where is the throttle of the car engine?

The throttle valve of the automobile engine is behind the air intake. Throttle is a controllable valve that controls air to enter the engine. After the air enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, and the combustion is successful. The position of the throttle valve is between the air filter of the air intake system and the engine block. Throttle is divided into: 1, traditional engine throttle: the operating mechanism works through a cable or a pull rod, one end of which is connected with the throttle pedal, and the other end is connected with the throttle linkage plate; 2. Electronic throttle: Through the throttle position sensor, the throttle opening is controlled according to the energy required by the engine, and the air intake is adjusted.
