What is the function and principle of automobile throttle?

The function of automobile throttle is mainly to control the intake flow of the engine, so as to control the air to enter the controllable valve of the engine and achieve a series of operating purposes. Generally speaking, air entering the trachea will be mixed with gasoline, and the combustible mixture formed will promote combustion. Generally speaking, throttles can be divided into two categories, namely electromechanical throttles and electronic throttles. Among them, the electromechanical throttle regulates the engine speed, which is related to the throttle opening. As for the electronic throttle, its signal is connected with the engine computer and can be adjusted through various parameters, thus realizing the function of sensitive control. Generally speaking, the working principle of the EFI vehicle is to provide electrical signals to the air flow sensor and air pressure sensor beside the throttle through the same action, and then the on-board computer controls them to inject fuel from the fuel nozzle according to the parameter values.
