Any operating point of the engine is found by two parameters: • Rotation Speed;
• Engine Load.
Having found these parameters through relevant processing, it is possible to calculate and obtain the injection (delivered fuel amount and relevant timing in relation to bursting TDC), the ignition (correct spark advance) and any
other function for each engine operating point.
The rotation speed is measured directly through the relevant sensor.
The engine load is determined indirectly trough a “density” parameter (representing the engine load) according to
the absolute pressure in the intake manifold and the intake air temperature.
The engine load is continuously detected from the LIEs and elaborated according to the user’s requirements (accelerator pedal): through the & $ 1line the / , ( Vsend the signal to the ETBs that control the throttle bodies
allowing the air in the intake manifold to reach a determined density (engine load).

speed-load parameter pairs, the time/ injection timing values and ignition spark advance required for correct engine
operation are stored.

by these three parameters.
All operation situations that require special adaptation of the calculated time/injection timing values, spark advance
and throttle bodies position are managed by the engine control unit, correcting the calculated base values through
suitable strategies according to the signals coming from the system sensors.

Cleaning
The fuel injection system could become damaged due to even slight contamination. During injection/fuel delivery system maintenance, pay attention to the following cleaning rules: •Thoroughly clean each point of connection and the areas near the engine before disconnecting the parts.
• Immediately close open connections and pipes with protection caps.
• Place the removed components on a clean surface and cover them. Use intact cloths.
• Install the clean components: Remove the spare parts immediately before installation. Do not use components
stored without their packaging (for example, in toolboxes, etc.).
• When the system is open: Do not use compressed air. Do not move the vehicle (unless absolutely necessary).
• Separated electrical connectors: Protect them from dirt and humidity. Make sure they are dry before reconnecting
them.

The anti-evaporation system prevents the fuel vapors, which consist of the lightest fractions of the hydrocarbons that form in the tank, from discharging into the atmosphere and being suctioned again to be burned.
The system operates especially when the outside temperature is high and the fuel temperature rises, thus increasing the tendency to evaporate. 2 S H U D W L Q J 3 U L Q F L S O H

Lifting System
This is an hydraulic device enabling to lift the front part of the vehicle when driving at low speed, to allow access to areas with uneven surfaces. The system is composed of the following components:•Front shock absorbers;
• Electronic control unit (GFA);
• Ascent or descent control button;
• Connecting hoses and electric wires;

E. 3 R Z H U V W H H U L Q J À X L G U H V H U Y R L U
F. Hydraulic pump
The system can be activated up to the maximum speed of 70 Km/h (30 Km/h for Japan); when it reaches this speed threshold the system will automatically go to the DOWN position. Moreover the system can recognize the following lifting system errors: • System pressure indicated simultaneously by two pressure switches as under 20 bars and over 70 bars (one or
both pressure switches damaged or disconnected).
• Vehicle ascending or descending time greater than 120 seconds (hydraulic or solenoid valve problem).
• Wrong vehicle speed indication.
The warning light on the dashboard will blink quickly to signal errors (it blinks slowing during raising/lowering).If problems occur the L.DAS software is used, which checks system errors and proceeds by resetting them.

The pressure inside the system reaches 20 bars and the minimum pressure switch ( ) L J ) opens.
Following occasional pressure increases (e.g. rough road surface), the minimum pressure valve ( ) L J ) opens.
The excess pressure is relieved by means of the solenoid valve ( ) L J ).
Furthermore, the ECU cyclically closes the solenoid valves for short times during vehicle operation (raising condition, see next paragraph) to keep the hydraulic circuit pressure in the range of 20 bars.
