1. Unscrew the plug ( A-Fig.1) of the expansion tank and top up with the prescribed type of coolant (000300) up to
50 ÷ 60 mm from the base of the cap.
2. Start the engine and run it at idle speed for some minutes leaving the radiator expansion tank plug open.
3. Adjust the air conditioner control to maximum heat and maximum fan speed (B-Fig.2); stop the engine and
check the coolant level through the radiator expansion tank plug; top up with coolant if necessary.
4. Close the cap
5. Wait for the engine to cool down (to below 80°C) and top up the coolant tank (Nourice) with the missing coolant.
6. Then tighten the radiator expansion tank plug.

The
G L U H F W L Q M H F W L R Q V \ V W H P ' , 6 is comparable to the running of an indirect injection engine. The basic difference
is that in this case, the fuel is injected directly into the cylinder.
This system better optimizes the amount of fuel to be injected, so consumption – and consequently emissions – are reduced. Characteristics of the system • A low pressure pump having an operation range between 6 and 4 bar,
• 7 Z R L Q W D N H P D Q L I R O G V H T X L S S H G Z L W K W Z R D L U À R Z P H W H U V W K D W P H D V X U H W K H À R Z D Q G W H P S H U D W X U H R I W K H D V S L U D W H G
air (one per manifold),
• Two high pressure pumps mechanically driven by the motion of the engine can reach a pressure varying
between E D U 0 , 1 D Q G E D U 0 $ ; .
• High pressure injectors that directly inject the fuel into the cylinder crown.
• A special piston that allows a vortex to be created, inside of which the fuel vaporized at high pressure is
sprayed.
The system is designed for the following types of operation: • V W R L F K L R P H W U L F V W U D W L ¿ H G P L [ W X U H
• homogeneous mixture,
• homogeneous and rich mixture.
, Q R X U V S H F L ¿ F F D V H homogeneous operation is used:

help with emissions.Homogenous and rich running is used only when there is a demand for torque.
When running at low speeds, the injection system is further aided by a tumble system inside the intake manifold that
helps the vortex created by the design of the piston, ensuring that the quantity of injected fuel goes directly beneath the spark plug. In this way the mixture is optimized with a lower quantity of fuel.
The injection of fuel during the compression phase of the cylinder is managed electronically by two injection control
units, of which one works as the MASTER and the other as the SLAVE .
The injection system is controlled by two linear oxygen sensors that alter the amount of fuel according to the demand
of torque and engine rpm. There are also two latest generation three-way pre-catalytic converters ( A-Fig.1) (with two
oxygen sensors for their control) and two post-catalytic converters incorporated inside the silencer ( B-Fig.1).

The energy necessary for evaporating the fuel is taken from the air contained inside the combustion chamber
that cools down. Thanks to this, it is possible to increase the compression ratio compared to that of an indirect injection engine.

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)
