Do Fuel Injectors Need Cleaning?

[EliLynn]

Fuel injectors do require cleaning, and the cleaning method is as follows: 1. Hang the cleaning device on the front hood of the car; 2. Locate the engine's fuel supply and return lines; 3. Disconnect the return line from the engine and use a suitable plug to block it; 4. Connect the fuel supply line to the outlet of the cleaning device; 5. Open the fuel tank cap and remove the fuel pump fuse to stop the fuel pump, thus completing the process. The functions of fuel injectors are: 1. To facilitate complete combustion; 2. To supply fuel to the engine. The working principle of fuel injectors is: When the electromagnetic coil is energized, it generates a magnetic force that lifts the needle valve, opening the injector nozzle. Fuel is then sprayed at high speed through the annular gap between the needle valve and the nozzle, forming a fine mist.
