What is the principle of the idle motor?

[VanLola]

The working principle of the idle motor is that the vehicle's computer collects engine operating condition data, calculates the optimal parameters, and transmits them to the idle motor. The idle motor then controls the size of the throttle's idle air passage to ensure stable engine operation. Since the idle motor regulates idle air flow, it is prone to getting dirty. Excessive dust entering the idle motor can impair its precise control and may even cause damage. If the idle motor fails, it will affect the car's idle operation, leading to issues such as difficulty starting, unstable idling, idle shaking, stalling at idle, and sluggish acceleration. If the idle motor is damaged, it should be replaced promptly. However, regular cleaning is crucial to prevent the buildup of carbon deposits and dust. As the idle motor is a precision component, cleaning requires positioning the motor's conical head downward and spraying cleaning agent onto the conical head and sleeve area to remove carbon deposits, followed by wiping it clean. This prevents cleaning agent from entering the motor's interior and causing damage.
