The fuel system consists of a low pressure part and a high pressure part.
The low pressure pump (LPP) (no.7) is located on t he left side of the engine and it su cks the fuel from the fuel tank.
The fuel drawn in by the low pressure pump en ters the pre-filter (5) where the water and the larger particles of impurities, that
may be present, are separated out.
This filter is equipped with a heater element (on certain applications) used to increase the temperature of the fuel in low
temperature conditions. There is also a mechanical pump on th e pre-filter that is used to prime the circuit. On reaching the low
pressure pump, the fuel is sent for filtering to the filter or filters depending on the applications (8). The pump pressure is maintain ed
at 5 bar.
The high pressure system is a common rail system consisting of a high pressure pump and 8 injectors, which is electrically
controlled by an ECM.
