How to clean Volvo xc90

Step 3 remove carbon deposits

1. The throttle valve 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.

2. Personally, I think there are two ways to clean the throttle. You can remove the throttle and clean it directly in the car. It is more convenient to remove and clean. If the throttle is dirty, just use a toothbrush.

3. Never spray on the throttle shaft when spraying, otherwise the throttle will be broken. When washing the car, spray the cleaning detergent on the cotton cloth to wipe the throttle, just clean up the carbon deposit, and finally match the throttle, and the idle speed will be higher just after cleaning.
