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

The aim is to maintain the engine rpm at around the memorised value, depending on the start-up temperature andthe start-up time itself. A throttle value and an ideal advance value are associated with each target rpm (which forms
a set point around which the system works to maintain the pre-established rpm).
• Start-up with cold engine
During the ignition transient with cold engine an offset on throttle bodies opening is managed according to
engine coolant temperature/ignition seconds.
• : D U P H Q J L Q H
When starting with a warm engine, a throttle bodies opening offset is applied based on the engine coolant temperature / ignition seconds and engine oil temperature in order to bring the engine to at least 1,000 rpm
and prevent vapor-lock. Following these operations the system goes to idle conditions where the control unit
automatically maintains the target rpm by carrying out the necessary corrections on the advance and air.

This is a differential device with a diaphragm, located in the front part of each fuel manifold and set by the manufacturerto a pressure of 4.00 ± 0.05 bars.
The fuel under pressure coming from the pump pushes onto the diaphragm ( C-Fig.3 R I W K H G R Z Q À R Z Y D O Y H '
Fig.3 ), opposed by the calibrated spring ( % ) L J ).

Furthermore, through the pressure tap ( A-Fig.3), the vacuum in the intake manifold (where the injector shutter is
also located), operating on the regulator diaphragm, proportionally reduces the load from the calibrated spring.
In this way the pressure difference is kept constant between the fuel and the environment in which the injector is located (intake manifold) under all engine operating conditions.

Injectors
The task of the injector is to deliver the amount of fuel required for the engine operation: The fuel is injected into theintake duct, immediately upstream of the intake valves.
As the pressure differential is constant between inside and outside the injector (due to the regulator), the quantity of
fuel delivered, with the same electric power depends only on the opening time, established by the control unit.
The injector is the “top-feed” type with the fuel supplied from the rear of the body ( H-Fig.4), where the electric
winding ( ' ) L J ) is also located, connected to connector ( ( ) L J ). The needle ( % ) L J ), integral with the anchor
( C-Fig.4 ), is thrust against the seal seat by a spring ( I-Fig.4).

To check the operation of the pressure regulator proceed as follows: • Connect a precision pressure gauge to the shut off tap, inserting it between the injector holder manifold and the
delivery coupling; check that the tap is open;
• Start up the engine and check that pressure p is within the prescribed values:
3.5 < p < 4.2 bar
If the pressure is above 4.2 bar: replace the pressure regulator.
If the pressure is below 3.5 bar: Check the fuel pump delivery pressure: If the delivery pressure is correct replace the pressure regulator (5 bars).
• Check that the pressure inside the system does not fall below 1 bar for at least 1 hour. If there are no visible
leakages, check the regulator and injectors.

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.
