Can I spray the fuel directly when cleaning?

Yes, but the throttle is still removed for cleaning. It may not be clean if you don't open it.

The main function of the throttle valve is to control the air intake according to the load of the engine. As for how often it is cleaned, it is determined by many aspects. Such as the driving environment of the vehicle and the control mode of the EFI engine.

If the vehicle works in a polluted environment (mainly inhalable particles), impurities will soon accumulate on the throttle valve, which will affect the intake of the engine for a long time, so it needs to be cleaned. This phenomenon is most obvious when starting the vehicle.

Throttle is a controllable valve that controls air to enter the engine. After the air 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.
