[GabrielaLee]

Car fuel injector cleaning method is: 1. Open the engine hood and hang the cleaning device on the front hood of the car; 2. Remove the return pipe from the engine connection point and block it; 3. Remove the inlet pipe from the engine connection point and connect it to the outlet pipe of the cleaning device; 4. Open the fuel tank cap and remove the fuel pump fuse; 5. Add cleaning agent into the storage bottle and adjust the pressure regulating valve knob to a smaller position; 6. Connect compressed air to the air inlet of the cleaning device and increase the pressure of the pressure regulating valve; 7. Open the inlet pipe valve of the cleaning device and start the engine. The fuel injector is a simple solenoid valve. When the electromagnetic coil is energized, it generates suction, the needle valve is lifted, and the fuel is sprayed out at high speed through the annular gap between the axial needle on the head of the needle valve and the injection hole, forming a mist that is conducive to complete combustion.
