High pressure fuel pump (HPFP) is the core pressurization component of diesel/gasoline direct injection engines, which pressurizes low-pressure fuel (3-6 bar) to 1000-1600 bar (diesel)/200 bar (gasoline), sends it to the common rail, and then injects it into the cylinder through injectors.
Working principle (diesel common rail)
Low pressure fuel inlet: The fuel transfer pump sends fuel (3-5 bar) into the inlet of the high-pressure pump.
Piston pressurization: The cam pushes the plunger upwards, reducing the pump chamber volume and compressing the fuel to 1600 bar.
Pressure control: The ECU controls the fuel intake through solenoid valves to stabilize the rail pressure; When overpressure occurs, the safety valve releases pressure.
High pressure fuel delivery: High pressure fuel is sent to the common rail and redistributed to the injec
