Engine fuel pump

Engine Fuel Pump

The engine fuel pump (also known as the "fuel pump") is a core component of the engine's fuel supply system. Its core function is to draw fuel from the fuel tank, pressurize it, and deliver it to the fuel supply line, providing a continuous and stable fuel supply to the engine. Using an electric motor or mechanical drive to generate suction, it draws fuel from the tank and pressurizes it to 0.3-0.5 MPa (for conventional electronic fuel injection systems) or 4-20 MPa (for high-pressure direct injection systems). It works in conjunction with the fuel pressure regulator to maintain a constant fuel pressure, ensuring a stable fuel flow to the injectors.
