The function of the electronic throttle is to control the opening angle of the throttle according to the energy required by the engine through the throttle position sensor, thereby adjusting the amount of intake air. The throttle opening can be determined according to the driver's needs and various driving conditions of the vehicle to ensure the vehicle's power and fuel economy. It also has control functions such as traction control and cruise control to improve driving safety. The throttle is a controllable valve that controls the air entering the engine. After the gas enters the intake pipe, it will mix with gasoline to become a combustible mixture, which will then burn to form work. It is connected to the air filter at the top and the engine block at the bottom, and is called the throat of the automobile engine.
