Working Principle

The high-pressure fuel pump pressurizes the fuel and sends it to the high-pressure common rail pipe, which distributes the high-pressure fuel to each injector. The pressure sensor on the common rail pipe monitors the oil pressure in the pipe in real time and feeds the signal back to the electronic control unit (ECU). According to the working conditions of the engine, the ECU controls the pressure regulating solenoid valve on the high-pressure fuel pump to accurately adjust the oil pressure in the common rail pipe to keep it stable and unaffected by the engine speed. When injecting fuel, the ECU controls the opening and closing of the solenoid valve on the injector, and sprays the high-pressure fuel in the common rail pipe into the engine combustion chamber with appropriate injection timing, injection amount and injection rate as needed.
