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).

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.

Injection System
The aim of the injection management strategies is to supply the engine with the correct amount of fuel at the required
moment according to the engine operating conditions.
The injection management is essentially the calculation of the injection time, the determination of the injection timingand the subsequent actuation through the injector control.
The “basic” injection time is calculated by a mathematical interpolation of the speed-load map: The values contained

that take into account the different engine operating conditions both at sea level and at altitude, which are indicated by the various sensors installed in the system.

Theoretical quantity of air to burn - All the injected fuel
The stoichiometric ratio depends on the type of fuel: For current unleaded petrol it is equivalent to approx. 14.7, that corresponds to a lambda titration = 1.

A rich mixture is when the air quantity is less than the stoichiometric quantity and in this case we have Ilios lambda <1;

also enables the engine control
unit to run its self-learning function.
The pre-catalytic oxygen sensors are linear and allow the engine to continuously operate under strengthcontrol; even in the WOT condition, the strength is guaranteed by the control system.
Cold Start and Running
The injection time during the starter motor actuation is determined by a special mapping according to the coolant and oil temperatures: After ignition has taken place the system passes over to the standard speed-load mapping.
When there is a cold start, since there is a natural impoverishment of the mixture due to reduced evaporation and heavy condensation on the inner walls of the fuel intake manifold, the “basic” injection time is increased by a

Acceleration and deceleration are interpreted by the system as transient stages between two stationary conditions:
This may be positive (acceleration) or negative (deceleration).
The transient strategy is very complicated since many factors have to be taken into consideration.
Usually the injection time is increased for positive transients and decreased for negative transients.
The size of the correction depends basically on the engine load variation: However, also values such as throttle
movement speed (inside the throttle bodies), engine speed, engine temperature (coolant and intake air) are also involved. Injector Control
The injector control is a timed sequential type. Rotation Speed Limiting
The strategy limits the peak speed that can be reached by enabling the cut-off when the engine reaches this speed.
Peak speed = 8150 rpm

Due to security reasons concerning the presence of throttle bodies the fuel pumps and injectors of cylinder bank 1-6
are supplied by relays controlled by LIE 7- 12 control unit and vice versa.
The pumps are stopped:
• If the engine speed drops under 350 rpm approx.;
• After a certain time (about 3 seconds) with the key to MAR position without starting up (timed enable);
Self-learning strategy
Self-learning only affects the optimum air percentage for the idle speed (0 to 60 seconds). The strength is kept constant with the target strength (value requested by the system under that particular operation condition).
The range of operation of the pre-catalytic oxygen sensor (linear) is 0.8 to 1.20.
If the value is below 1.00, the system is RICH; otherwise, the system is POOR.
The self-learning values of the linear oxygen sensors are always saved in the control unit during normal
operation.

This strategy checks the position of the canister washing solenoid valve in this way: • With the engine hot the control unit operates the solenoid valve so as to check the quantity of fuel vapors sent to
the intake (canister washing), according to the engine speed and load. The system alternates washing periods
with no washing periods: During the latter the self-adaptation strategy can be enabled, if these conditions
occur.
• During start-up the solenoid valve remains closed, preventing the fuel vapors from enriching the mixture;
