What is the serious jitter of air conditioning engine?

The most common cause of engine jitter caused by turning on the air conditioner is that the throttle is dirty, which affects the engine. If the air conditioner is turned on again at this time, the idle speed of the engine will increase and the steering wheel will shake.

The engine has a serious carbon deposit, and the most common reason for car jitter is that the throttle valve is too dirty or the 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 the carbon deposit during cold start.

The mixture that leads to cold start is too thin, which 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, and the mixture will become rich.

Extended data:

If the engine has a large displacement, the compressor will have less influence on it, so you won't feel too much jitter, even after the driver drives. Because of the large displacement and high power, the proportion of engine power consumed by the compressor is very small, and the overall impact is very small.

However, it is not only related to the power of the engine, but also related to the type of compressor. Later, when the temperature in the car reaches the preset value, the variable displacement compressor will not work at full load, and the displacement of the compressor is smaller, that is, the power is smaller, and the impact on the engine is smaller, so the variable displacement compressor will also save more fuel.
