Control and power limitation strategies
The ECU controls rpm limitation using different maps, depending on the environmental conditions at the time: • with engine cold (Water temperature < 60°C) and with low Toil (Oil temperature < 40°C), the rpm are limited
• with engine hot (Water temperature > ƒ & W K H U S P D U H O L P L W H G

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)

Tumble system
The tumble system is made up of diaphragms commanded according to the characteristic diagram of the engine,
and are used to restrict emissions. The diaphragms are closed (so the valve is disabled) at low speed and low load.There are two operation speeds depending on the water temperature.

cylinder.
The intake manifold diaphragms are opened, releasing the entire section of the duct when power is demanded of
the engine. All diaphragms of a cylinder bank are fastened to a common camshaft.
The position of the intake manifold diaphragms for each cylinder bank is checked by the Hall sensors which, in the
event of incorrect reading, send the information to the ECU that turns on the engine malfunction warning light. This information can be seen using the LaRa-AS .
The intake manifold diaphragms are enabled by a cylinder bank vacuum positioner in the engine for high rotation
speeds. Feedback of the position of the diaphragms is provided in this case as well, through the Hall sensors. In
the case of malfunctioning, they send the information to the ECU. Also in this case the errors can be read using the LaRa-AS .
The system is in stand-by (therefore enabled) with the engine cold, TH2O < 60°C, and with a torque demand
< 40% beneath 2000 rpm.
The system is operating (therefore disabled) with the engine hot, TH2O > 60°C, and with a torque demand < 40%
beneath 3000 rpm. The activation solenoid valve for the vacuum system is underneath the intake manifold: • it is enabled when the intake manifold is closed
• it is disabled when the intake manifold is open
