Byd fo idle motor model

There are several models: Delphi, UMC and Bosch. The model number is11125/d 5184.

Idle motor is an element to control the idle speed of automobile. When the engine is idling, it is called idling.

The function is to change the cross-sectional area of idle air passage according to the temperature and load when the engine is idling, so that the engine has the best idle speed under different working conditions.

Idle motor is mainly used to bear the idle speed of the car, and its purpose is to adjust the idle speed according to the engine load when idling. Idle stepper motor is installed on the throttle body and used by the engine controller to control the idle speed of the engine. When the engine speed deviates from the idle speed, it is adjusted by the throttle valve to control the amount of air entering the intake manifold, which is mechanically operated by the accelerator pedal wire rope. The throttle body has a bypass air passage to provide air when the engine is idling (when the throttle is closed). The pivot of the automatic idle motor extends into the bypass air channel, through which the air flow is adjusted. According to the input signals of various sensors, the engine controller adjusts the engine idle speed by moving the pivot of the automatic idle motor into and out of the bypass air passage. When the ignition key is turned to the on position, the automatic idle motor starts to work. The switch signal is input to ECU to detect whether the engine is idling. At the same time, the instantaneous position of motor is fed back to ECU through motor position sensor.
