What will happen if the throttle valve is not cleaned after 65438+ ten thousand kilometers?

The throttle valve will become dirty, and a layer of sludge and dirt will be attached to itself and the inner wall of the nearby airway, which is called carbon deposition.

If the throttle valve is not cleaned for 654.38+ 10,000 kilometers, the carbon deposition will be very serious, which will cause congestion and affect the intake of the engine, leading to the idling jitter and flameout of the car, the acceleration will not be smooth, and the fuel consumption will increase accordingly.

The main symptoms of dirty automobile throttle are engine jitter, unstable idle speed and difficulty in starting a cold car. There are many reasons for dirty throttle valve, mainly caused by the condensation and accumulation of oil vapor caused by long-term back diffusion of crankshaft ventilation pipe or the escape of exhaust gas and mixed gas from cylinder.

Extended data:

After the gas enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, and the combustion is successful. It connects the air filter and the engine block, and is called the throat of the automobile engine.

Throttle four-stroke gasoline engines are generally like this. Throttle is one of the most important components in EFI automobile engine system. Its upper part is the air cleaner grille, and the lower part is the engine body, which is the throat of the automobile engine.

Whether the acceleration of a car is flexible or not has a lot to do with the dirt of the throttle. Cleaning the throttle can reduce fuel consumption and make the engine flexible and powerful.
