What is the use of throttle and idle speed control valve?

Function of throttle and idle speed control valve: 1. Throttle is a controllable valve that controls air to enter the engine. After the gas enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, and the combustion is successful. Known as the throat of an automobile engine, it is connected with the air filter and the engine cylinder. 2. The idle control valve is installed on the vent hole beside the throttle, and the idle controller makes the idle control valve act in time to improve the engine speed when the engine speed is lower than 750RPM according to the ignition signal, and stops acting when the engine speed exceeds 1050RPM; 3. For vehicles equipped with air conditioning system, this control valve is also called idle acceleration valve. After the air conditioning compressor operates, the engine load will reduce the engine idle speed, and the idle speed control valve will act accordingly to maintain the stability of idle speed.
