Yi Rui's vacant seat is a little shaky. What happened?

When sitting in the car at idle speed, I feel slightly shaking. The most common reasons are that the throttle is too dirty or the fuel injector has too much carbon deposit. When there is too much carbon deposit in the engine, the gasoline sprayed by the injector will be absorbed by a large amount of carbon deposit during cold start, which leads to the lean mixture during cold start and the difficulty in starting.

The idle seat can feel the vibration. For gasoline vehicles, seat vibration can be felt when idling. If the vibration is slight and regular, it is normal. If the vibration is very severe, there is something wrong with the car.

At first, as long as it is a gasoline engine, there will be more or less jitter during operation. Because the engine is basically composed of machinery, there will be more or less necessary vibration, but the degree of vibration is different.

For example, a million-class luxury car, because of the special number adjusted by the staff, the shaking and vibration will be very slight and almost imperceptible. If it is a shopping cart with a price of100000 yuan, it is definitely impossible to adjust it well because of the cost. If it shakes, it will be clearer.

Pure electric vehicles will not shake, because pure electric vehicles use motors to drive cars by current.

But if the shaking is obvious, there may be quite a few reasons. Generally speaking, the position of any one of fuel system, air intake system and ignition system may basically affect the phenomenon of idle vibration.

For example, insufficient air intake, spark plug failure, poor gasoline atomization, vehicle fuel injection quantity change, oxygen sensor surface carbon, throttle blockage and so on. , will basically affect the phenomenon of idle vibration.

Specific needs professional testing to determine.
