What is the purpose of cleaning fuel injectors?

Cleaning fuel injectors serves the following purposes: It can improve the issue of vehicle exhaust emissions pollution. When fuel injectors malfunction due to carbon deposits, the mixing and combustion of the combustible air-fuel mixture will be affected to some extent, leading to increased pollution in vehicle exhaust emissions. A fuel injector is essentially a normally closed valve. When the electromagnetic coil is energized, it generates a magnetic force that lifts the needle valve, opening the injection hole. Fuel is then sprayed at high speed through the annular gap between the needle valve head and the injection hole, forming a fine mist that facilitates complete combustion. As one of the key components of an electronic fuel injection engine, the performance of the fuel injector significantly impacts the overall engine performance.
