Fuel pump
There is only one electric fuel pump (
A-Fig.6) and it is in the right tank. This pump is controlled by an ECU ( B-Fig.6)
which in turn is controlled by the master control unit.
The pump has an operating pressure ranging between 4 and 6 bar, depending on the various operating conditions
of the vehicle.
The pump sends the fuel to the two high pressure pumps (which are mechanical) that compress the fuel and take the pressure to a value varying from 120 to 140 bar, according to vehicle operation.
Both the high and low pressure pumps are monitored by two sensors installed on the respective lines to prevent overpressure problems. Linear phase transformers
Linear phase transformers allow the engine phase to vary according to the torque required in order to always have optimum phasing.
In this version they are always enabled, and the phasing follows different maps according to the load and the atmospheric conditions. Piloting is performed by a solenoid valve ( A-Fig.7), which makes the oil pass inside the phase-changing gear.
This operation is managed by the injection control units that also receive the position of the camshaft through the
Hall effect sensors ( B-Fig.7) mounted on the camshafts:
• two sensors for the exhaust (one per cylinder bank)
• two sensors for the intake (one per cylinder bank)
