Fuel Delivery – High Pressure (HP) Side
The HP fuel pump supplies fuel to the fuel rail. The pump is directly driven by the engine and is located at the front of
the engine block. Fuel rail pressure is variable to allow for fuelling strategies such as noise limitation and surge control.
The maximum fuel pressure is 1300 bar (18850 lbf/in 2 ).
Fuel pressure is controlled by the ECM via the fuel pressure regulator valve located at the rear of the HP fuel pump.
The ECM uses the output signal from the fuel rail pressure sensor, mounted on the end of the fuel rail, to maintain the
optimum fuel pressure for the current conditions. The fuel pressure regulator reduces pressure by diverting fuel from
the HP output back to the fuel tank.
The minimum operating pressures are 200 bar (2900 lbf/in 2 ) during cranking and 300 bar (4350 lbf/in 2 ) during idle,
failure to reach these pressures will result in a non start situation, stalling or erratic idle.
