What is the working principle of throttle?

Working Principle of Throttle: 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, which will be successfully formed after combustion. The accelerator pedal position sensor transmits the information that the driver needs to accelerate or decelerate to the accelerator electronic control unit, and the ECU calculates the corresponding accelerator position according to this information, and sends a control signal to the accelerator actuator, which opens the accelerator to the calculated opening position. The ECU communicates with other electronic control units, such as engine electronic control unit, automatic transmission electronic control unit, etc. ), and constantly correct the throttle position according to the obtained throttle position sensor information, engine speed sensor signal and vehicle speed sensor information, so that the throttle opening can reach the ideal position required by the driver.
