Where is the Volvo xc90 throttle?

Open the engine cover of Pacific Auto Network, and remove the hose connecting the air filter and the throttle valve. After removing the hose, the throttle valve can be seen. 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.

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.

Don't spray it on the throttle shaft when cleaning, otherwise it will damage the throttle. When washing the car, spray it on cotton cloth to wipe the throttle and clean up the carbon deposit. Finally, as long as the throttle is matched, the idle speed will be higher just after cleaning.
