How to Use Fuel Injector Cleaner?

[RowanRose]

The method of using fuel injector cleaner is: 1. Pour the fuel injector cleaner into the hanging bottle, and connect the hose of the hanging bottle to the engine fuel injection common rail; 2. Start the engine. The fuel injector is located on the intake manifold of the direct-injection cylinder block. Its working principle is: when the electromagnetic coil is energized, it generates suction force, lifting the needle valve and opening the injection hole. Fuel is sprayed at high speed through the annular gap between the needle valve head and the injection hole, forming a mist for complete combustion. Common faults and solutions for fuel injectors: 1. Clogged injection hole: Grind with chromium oxide on a flat plate; if the cylindrical surface of the needle valve is severely worn, replace it promptly; 2. Poor sealing: Apply chromium oxide or toothpaste to the sealing band at the end of the needle valve; 3. Piston wear: Replace the piston.
