What is the reason for the sudden shaking of herdsmen at high speed?

There are generally two reasons. One is carbon deposition in the intake system, that is, there is a large amount of colloidal carbon deposition near the valve seat and around the idle motor, which leads to the mixture being too rich and too lean. Will form the phenomenon of idle jitter, especially when the cold car starts.

Second, the throttle valve is too dirty, because there is too much colloidal carbon or dirt around the throttle valve plate, and the cross-sectional area of the air passage will change, which makes the control unit unable to accurately control the idle intake, resulting in the mixture being too rich or too thin.

Matters needing attention

1, automobile engine maintenance

Car engines should be cleaned at the right time. Because long-term use will form a thick layer of carbon deposit on the engine surface, which will have a great corrosive effect on the rubber parts in the engine.

2, gasoline and water to prevent evaporation.

In summer, the temperature is generally higher. So gasoline and water evaporate more easily than usual. Because the water tank and oil tank should be checked frequently, gasoline and water should be added in time when there is little.

3. Pay attention to the hygiene inside the car.

Summer is the fastest season for bacteria to multiply, so it is necessary to keep the car clean, especially the car seat cushion, steering wheel cover and car mat.
