How long does it take to clean the car nozzle?

The nozzle of an automobile can be cleaned once at about 20000 ~ 30000km, and the condition and oil quality of the automobile can be extended to about 40000 ~ 60000km.

As one of the key components of EFI engine, the performance of injector will be seriously affected. Nozzle blockage will seriously affect the performance of the car. The reason for the blockage is that carbon deposits in the engine are deposited on the fuel nozzle or impurities in the fuel block the fuel nozzle channel. After the car runs for a period of time, the fuel system will form certain deposits.

Therefore, it is necessary to clean the nozzle regularly. Long-term non-cleaning or frequent cleaning of the nozzle will have a bad influence.

Extended data:

When cleaning is needed, it is necessary to choose the specific time-the control of fuel injection quantity: for the same type of EFI vehicle, the pressure of the gasoline pump is constant, and the pressure of the injector is always constant as long as it is adjusted by the fuel pressure regulator, regardless of the throttle opening.

The fuel nozzle is strictly matched with the fuel pump and fuel pressure regulator. Only under the designed pressure can the fuel nozzle achieve the best atomization effect. The pressure is lower than the design pressure, and the sprayed oil is not in the form of fog, but columnar, and should not be mixed with air. When the pressure is too high, the sprayed oil is conical and difficult to mix. Moreover, the injection force is too large, and a lot of fuel is directly sprayed on the pipe wall, which directly affects the mixing ratio parameters.
