Under What Circumstances Should the Car Fuel Injectors Be Cleaned?

[DelPresley]

The following situations require cleaning the car fuel injectors: 1. Using low-quality gasoline, which may clog the injectors due to excessive impurities in the fuel. 2. Poor fuel injection or the presence of carbon deposits and adhesives in the injector gaps. 3. Failure to meet the designed fuel injection volume or atomization effect. Functions of the fuel injectors: 1. Control of fuel injection volume: For the same type of fuel-injected vehicles, the fuel pump pressure remains constant. 2. The fuel injectors must be used in strict coordination with the fuel pump and fuel pressure regulator. Only when the design pressure is reached can the injectors achieve optimal atomization. If the pressure is below the design level, the fuel is ejected in a columnar shape, making it difficult to mix with air. If the pressure is too high, the fuel is ejected in a conical shape, which is also difficult to mix, and the excessive injection force causes much of the fuel to directly hit the pipe wall, affecting the air-fuel mixture ratio parameters.
