What happens when the electromagnetic clutch sucks when it doesn’t?

The phenomenon that the electromagnetic clutch sucks sometimes and does not suck is because the idle speed of the engine is unstable. When the amount of refrigerant injected into the car air-conditioning system is too much, the cooling effect will be reduced, resulting in abnormal operation of the compressor and unstable idle speed of the engine.

　　

During the running of the car, the driver separates and connects the engine and the gearbox by manipulating the clutch, thereby cutting off or transmitting the power input from the engine to the gearbox. The clutch is the device connecting the transmission system of the car with the engine. For cars with manual transmission, the clutch is an important component of the power system of the car. During the driving process of the car, the use of the clutch reflects the level of the driver's driving level. The clutch can be divided into For electromagnetic clutches, friction clutches and hydraulic clutches. During the driving process of the car, the speed of the car can only be increased when the clutch is fully engaged.
