The LIE system is a system that integrates a digital electronic ignition spark advance and static timing system with an electronic indirect fuel injection system of the multiple timed sequential type.
According to the engine structure, which has the cylinders divided into two cylinder banks, two complete systems that
are suitably synchronized with each other have been applied, and each controls a cylinder bank of six cylinders. As
a consequence there are two engine control units, connected to each other by the CAN line, managing the injection
and ignition of each cylinder bank and four throttle bodies connected to each other by CAN lines and electronically
controlled by LIE control units through the ETB control units. These control units are also connected by the CAN line
to the GFA control unit that co-ordinates and manages many functions especially concerning diagnostic. The system can be divided into the following sub-systems: ELECTRICAL/ELECTRONIC SYSTEM
FUEL SUPPLY SYSTEM
INTAKE SYSTEM
THROTTLE BODIES GENERAL DESCRIPTION
EXHAUST SYSTEM
ANTI-EVAPORATION DEVICES The system can properly acquire the following parameters: •Engine speed;
• Correct TDC sequence of the cylinders (injection timing);
• Absolute pressure in the intake manifold;
• Throttle position and position variation;
• Accelerator pedal position;
• Intake air temperature;
• Engine coolant temperature;
• Exhaust gas internal temperature;
• Mixture strength;
• Battery voltage;
• Possible start-up of air conditioner;
• Pressure in the exhaust manifold;
• Pressure in the fuel anti-evaporative circuit.

The accelerator pedal position sensors are two potentiometers both coaxially installed in the same casing and activated by the accelerator pedal by means of a shaft.
The accelerator pedal angle position is detected by the two coaxial potentiometers: The signal is sent to

units and then to (7%FRQWUROXQLWV (one per cylinder bank), which in turn control the respective throttle bodies.

Absolute pressure sensor operating principle
The sensitive element, enclosed in a plastic container, consists of a Wheatstone bridge stenciled on a very thin ceramic plate (diaphragm) installed on the lower part of an annular support.
The diaphragm separates two chambers: In the lower chamber, which is sealed, a vacuum has been created, whereas the upper chamber is in direct communication through piping with the measuring point.
When operating, the pressure that generates on the measuring point produces a mechanical action on the sensor GLDSKUDJPZKLFKGHÀHFWVWKXVYDU\LQJWKHUHVLVWRUYDOXHV
Since the power supply is constant (+5 V), the resistor variation causes an output voltage variation ( 9)LJ) which
is proportional to the pressure value.

The reference voltage is 5 Volts: Since the control unit input circuit has been designed as a voltage divider, the reference voltage is divided between a resistor in the control unit and the sensor itself.
As a result, the control unit is able to assess the sensor resistance variations through the voltage changes, thus receiving information on the temperature.
The air temperature sensor is incorporated with the absolute pressure sensor: a single sensor with two functions.
