What is the idling vibration of wing beat C30?

There may be the following four reasons for the body shaking at idle speed: 1. The engine carbon deposit seriously leads to the body shake, and the most common reason is that the throttle valve is too dirty or the injector has too much carbon deposit. When there is too much carbon deposit in the engine, the gasoline sprayed by the fuel injection head will be absorbed by the carbon deposit during the cold start, which leads to the lean mixture during the cold start and makes it difficult to start. In this case, only when the gasoline adsorbed by carbon deposits is saturated, it is easy to run into the car. After running into the car, the gasoline adsorbed on carbon deposits will be sucked into the cylinder by the vacuum suction of the engine for combustion, which will thicken the mixture and dilute the combustible mixture of the engine, resulting in idling jitter after cold start. 2. Ignition system problems Check the working conditions of spark plugs, high-voltage lines and ignition coils. Poor working conditions of ignition system and spark plug can also lead to such failures. 3. The oil pressure is unstable. If the engine carbon deposit has been cleaned, the throttle valve has been cleaned, and the spark plug has been replaced. , the body is still shaking at idle speed. It is recommended to check whether the oil supply pressure and intake pressure sensors are normal. If the oil supply pressure of the oil pump is abnormal or the value of the intake pressure sensor is wrong, the car body will shake. 4. The aging of engine parts and automobile jitter are also related to the aging of engine feet. The engine foot is responsible for absorbing slight vibration 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, causing idling jitter.
