The reason why the engine sound becomes louder
The following are the reasons why the engine noise is getting louder and louder: 1, the throttle is dirty or stuck, the compressor will work after the air conditioner works, and the compressor is driven by the engine, so the load of the engine will increase after the air conditioner is turned on, that is to say, the engine should increase the throttle opening and increase the air intake. When the throttle valve has carbon deposit or is stuck, it will cause engine jitter and abnormal noise. This will be more obvious after turning on the air conditioner; 2. Abnormal sound of air conditioning pump. There are two main reasons for abnormal sound of air conditioning pump: electromagnetic clutch and bearing in air conditioning pump. The abnormal sound of electromagnetic clutch is mainly caused by the wear of electromagnetic clutch, and the abnormal sound of air conditioning pump bearing is mainly caused by the lack of lubricating oil. If these two problems are not solved in time, the air conditioning pump will be burned out and refrigeration cannot be carried out. 3. If the tightness of the compressor drive belt is poor and the drive belt is too loose, the electromagnetic clutch is easy to slip; If the drive belt is too tight, the load on the electromagnetic clutch will increase. Improper tightness of the drive belt will produce abnormal sound, and excessive belt will damage the air conditioner compressor.
