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.
