Where is the 4th generation Bluebird idle motor?

The idle motor of the automobile is mainly used to bear the idle speed of the automobile on the accelerator conveyor, and its purpose is to adjust the idle speed according to the engine load at idle speed.

When the engine speed deviates from the idle speed, the amount of air entering the intake manifold is controlled by throttle adjustment, and the accelerator pedal wire rope is mechanically operated. The throttle body has a bypass air passage to provide air when the engine is idling. The pivot of the automatic idle motor extends into the bypass air passage to adjust the air flow. According to the input signals of various sensors, the engine controller adjusts the idle speed of the engine by moving the pivot of the automatic idle motor into and out of the bypass air passage.

Idle motor damage symptoms

If too much dust enters the idle motor, it may cause the idle motor to be damaged, and the idle motor may be stuck in a certain position and unable to rotate, resulting in the engine not being accurately controlled at idle speed, thus causing the car to have symptoms such as flameout, idle flameout, unstable idle speed, engine jitter and slow acceleration.

Idling motor has no specific service life, so it can be used to scrap cars without accident, but it is related to the actual use. If it is not cleaned regularly, it will deteriorate faster. Therefore, we should pay attention to replacing the air filter at ordinary times, and don't use the dirty air filter for a long time, otherwise too much dust will enter the idle motor, which will cause the idle motor to be damaged.
