What should I do if the engine idle speed of the five j6l engine in Jiefang State is unstable and the cab shakes badly?

1. When the vehicle shakes, check the throttle and fuel injector first. If the throttle valve is found to be too dirty or the fuel injector has too much carbon deposit, it should be cleaned in time.

2, the engine pad aging, car jitter is sometimes related to the aging of the engine pad. The engine foot is actually the shock absorption system of the engine, and the engine foot is responsible for absorbing the slight jitter when the engine is running. If there is something wrong with the engine foot, these vibrations will be transmitted to the steering wheel and cab, which will lead to the idling state of the automobile engine when it is idling, and it is most likely to cause the automobile to shake when the automobile electrical system is turned on. The engine will increase the load due to turning on the electrical system, resulting in idling and slipping. In order to compensate for the jitter caused by idle speed, the engine will automatically raise the speed. Therefore, when the automobile electrical system is turned on, especially when the automobile air conditioner is started in summer, the engine often shakes. If the jitter in idle state will not be reduced due to the operation of the compressor of the car air conditioner, then this jitter is probably caused by the aging of the engine foot, and it is necessary to replace the engine foot in time. Uneven tire weight is also the cause of jitter.

3, tire aging, deformation, and the jitter of the car during driving are far more worrying to the driver than the jitter at idle speed. Vehicle vibration is mostly related to the transmission system, and the most basic part is the tire problem. The above hopes to help you, hope to adopt!
