What is the problem of engine jitter of Changan van?
1, engine carbon deposit is serious. After driving for several kilometers, the throttle valve is too dirty, which will lead to lax closing or motor hysteresis, resulting in excessive engine idle speed. The carbon deposit produced in this process will lead to vehicle jitter, especially when starting the vehicle, the engine jitter will be more severe than usual, so it is necessary to clean up the carbon deposit in time.
2. Ignition system problem. When the cold car is started, the engine needs rich mixture, and the mixture needs high ignition energy. If the spark plug gap is too large, the ignition coil and high-voltage coil will age, which will lead to the reduction of ignition energy and make the body tremble. Check the spark plug and cylinder pipeline, and adjust or replace it if it does not meet the requirements.
3. The oil pressure is unstable. Abnormal oil supply pressure of oil pump or incorrect value of intake pressure sensor will cause body shake. Remember to check the oil pressure and replace parts if necessary.
4. Shock absorption system. The engine foot is actually the damping system of the engine. If there is something wrong with the engine foot, these vibrations will be transmitted to the steering wheel and cab, causing idling jitter.
