Why did Changfeng Mitsubishi Pajero v73 start to shake?

The most common cause of automobile jitter is that the throttle valve is too dirty or the fuel injector has too much carbon deposit.

1. When there is too much carbon deposit inside the engine, the gasoline sprayed by the fuel injection head will be absorbed by the carbon deposit during cold start, which will lead to too thin mixture during cold start and make 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. The lower the temperature, the more oil is needed for cold start, and the existence of carbon deposit will affect the smooth start.

2. It is inevitable that the engine will produce carbon deposit, but when the engine has too much carbon deposit, it will lead to poor engine work and different faults. 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. It is not easy to enter the car before the gasoline absorbed by carbon deposits reaches saturation. After entering 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. Solution: clean the oil circuit, check whether there is carbon deposit in the idle motor, and clean it.

3. If you are a novice, the driving school coach has a high idle speed and can walk smoothly without refueling at first. However, almost all manual gears on the market need a slow throttle when starting.

4. If you are an old hand, the cause of starting jitter is generally the wear and slip of clutch pressure plate and disc, mostly due to aging or quality. This requires replacing the pressure plate and brake disc at the same time. Please note that they are replaced together.

No matter what the reason is, when you start, you should loosen the clutch according to your feelings and slow down the throttle. Only after you are proficient can you strive for the starting speed at the traffic lights.
