The N52KP and N51 engine continue to use the conventional "manifold
injection" system carried over from the N52. The fuel supply components are also
carried over with regard to the EKP module, fuel
The fuel is delivered from the fuel tank by the electric fuel pump via the
feed line (5) at an "feed" pressure of 5
bar to the high pressure pump. The feed pressure is monitored by the
low-pressure
If a fault is diagnosed in the system, such as e.g. failure of the
high-pressure sensor, the fuel-supply control
valve is de-energized; the fuel then flows via a so-called bypass into the rail.
