Golf 7 How long does it take to clean the nozzle throttle?

If there is a problem, wash it again. There is no fixed cleaning time.

The injector itself is a normally closed valve (normally closed valve means that the valve is always closed when there is no control signal input; When there is no control signal input, the normally open valve is always open. The valve needle moves up and down to control the opening and closing of the valve. When the ECU sends the fuel injection instruction, its voltage signal will make the current flow through the coil in the fuel injector, generate a magnetic field to attract the valve needle and open the valve, so that the fuel can be ejected from the fuel injection hole. The biggest advantage of jet fuel supply is that the control of fuel supply is very accurate, so that the engine can have the correct air-fuel ratio in any state, which not only keeps the engine running smoothly, but also conforms to the norms of environmental protection laws and regulations.

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. Whether the throttle should be removed for cleaning is also the focus of discussion among car owners.
