What is the serious fever of Geely Job's engine?

The normal operation of Geely Job engine in Pacific Auto Network depends on lubrication and heat dissipation, and the trembling of automobile engine is probably caused by oil shortage or oil deterioration. The most common cause of automobile vibration caused by serious engine carbon deposition is that the throttle valve is too dirty or the injector has too much carbon deposition.

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, it is easy to run into the car only when the gasoline absorbed by carbon deposits is saturated. After running into the car, the gasoline adsorbed on the carbon deposit will be sucked into the cylinder by the vacuum suction of the engine for combustion, which will make the mixture rich, and the combustible mixture of the engine will be diluted and concentrated, resulting in idling jitter after cold start.

2, ignition system problems, check the working conditions of spark plugs, high-voltage lines and ignition coils. If the ignition system is not working well and the spark plug is in a bad state, it will also lead to this failure phenomenon;

3. The oil pressure is unstable. If the engine carbon deposit has been cleaned, the throttle has been cleaned, the oil pad and spark plug have been replaced, and the body is still shaking at idle speed. I suggest you go to the 4S shop 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 actually the damping system of the engine. 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.
