What is the relationship between electronic throttle and idle speed control valve?

1. The throttle valve 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. It connects the air filter and the engine block, and is called the throat of the automobile engine.

2. The idle speed control valve is installed on the vent hole beside the throttle. According to the ignition signal, when the engine speed is lower than 750 rpm, the idle control valve will be activated in time to increase the engine speed, and when the engine speed exceeds 1050 rpm, the idle control valve will stop working.

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 is generated, which reduces the engine idle speed, and the idle speed control valve acts accordingly to keep the idle speed stable.
