How to maintain the nozzle of EFI motorcycle?

According to the car condition and the quality of fuel added at ordinary times, generally speaking, it is recommended to clean it once every 20 ~ 30 thousand km. The car is in good condition and the fuel quality can be extended to about 40,000 ~ 60,000 kilometers. When the injector is slightly blocked, it also has a certain impact on the vehicle condition.

Before starting the engine, it is necessary to remove the relay of the fuel pump in the fuse box to stop the fuel pump. Because the fuel manifold is not connected with any equipment at this time, if the fuel pump continues to pump oil at this time, the fuel will flow directly from the fuel manifold.

The DC impedance value of the fuel injector coil is generally (at the temperature of 20 2℃):12.25 0.50Ω, and the resistance values of different vehicles are different, please refer to the resistance values specified in the operating instructions of each vehicle). If the measured resistance of the fuel injector differs greatly from the instruction manual, the fuel injector assembly must be replaced.

2. Check and adjust the injection pressure and atomization quality in time to ensure proper atomization cone angle and correct injection advance angle; Clean up the carbon deposit in time, and be careful not to touch the spray hole and all sealing surfaces.

3. After the carbon deposit is removed, generally, the sealing cone can be ground with engine oil or special grinding paste, and then thoroughly cleaned, and then reassembled and debugged. Note that coupling parts should be installed in pairs and cannot be interchanged.

4. During use, avoid overheating of the fuel nozzle, which will affect its normal work. When the fuel nozzle is overheated, it will cause the needle valve of the fuel nozzle to work abnormally, deposit carbon on the nozzle hole and shaft pin, and even kill the needle valve.
