How often does Chery QQ throttle clean?

Generally, it is cleaned once every 20,000 kilometers, without strict restrictions, which has a lot to do with car habits and the environment. If it is dirty, it should be washed. When the idle speed is unstable, you should consider cleaning.

Failure to clean the throttle for a long time will lead to an error in the throttle opening, and air with impurities will enter the combustion chamber of the engine. These two results will lead to abnormal engine operation, mainly manifested in unstable idle speed, sudden feeling of throttle when driving, reduced power, and even difficult starting and increased fuel consumption.

Throttle is a controllable valve, which is used to control air to enter the engine. After entering the intake pipe, it is mixed with gasoline (different models of cars have different design mixing parts) to become combustible mixture, which participates in combustion and does work. Four-stroke gasoline engines are generally like this. Throttle is the most important component in EFI automobile engine system. Its upper part is the air filter, and the lower part is the engine block, which is the throat of the automobile engine. Whether the acceleration of a car is flexible is closely related to the cleanliness of the throttle.
