DIESEL EQUIPMENT
General
13
The use of electronic injection in Diesel engines has allowed the operational power of these engines to be
optimised, thus reducing the emission rate of pollutant gases.
The system consists of a computer, which receives information from:
- the coolant temperature sensor,
- the air temperature sensor,
- the engine speed sensor,
- the vehicle speed sensor,
- the load potentiometer,
- the injection start sensor, which forms part of the injector of cylinder n° 3 (injector with sensor).
It controls :
- the injection pump :
• the altimetric corrector (F8Q 630) via a relay
• the advance solenoid valve.
- the cold engine starting system (heater plugs and pre-postheating unit),
- the exhaust gas recycling system (EGR),
- the diesel injection fault warning light,
- the preheating warning light,
- the solenoid valve controlling the fast idle speed LDA,
- the relay controlling the power assisted steering electric pump assembly (for vehicles with air conditio-
ning), the pump assembly is supplied once the engine speed exceeds 650 rpm.
It carries out a self diagnosis procedure which may be visualised through the
XR25.
SPECIAL FEATURES
On the injection pump it is possible to replace:
- the load potentiometer,
- the advance solenoid valve,
- the altimetric corrector,
- the electrical solenoid.

OPERATING PRINCIPLE OF THE DIESEL INJECTION WARNING LIGHT ON THE INSTRUMENT PANEL
On switching on the ignition, the diesel injection fault warning light is illuminated. It extinguishes as the en-
gine begins to run.
•Fault in a component of the injection assembly
Faults in the following components may cause the warning light to illuminate :
- injector with sensor
- advance solenoid valve,
- engine speed sensor ,
- load lever potentiometer,
- pre-postheating (according to version).

DIESEL EQUIPMENT
Pre-postheating control
13
The pre-postheating function is controlled by the
computer, which controls the preheating plug re-
lay housing.
1) Ignition - Preheating
The preheating process is divided in two
phases :
a) Variable preheating
This is dependent on the coolant tempera-
ture, on the battery voltage and on alti-
tude (internal computer sensor) when the
ignition is switched on (the preheating
warning light illuminates).b) Fixed preheating
After the preheating warning light has
extinguished (variable preheating), the
plugs remain fed for 8 seconds before the
engine is started.
2) Starting the engine
During the action of the starter motor, the
four plugs are fed continuously.
3) Engine running - Postheating
The postheating also may be divided in two
phases:
a) Fixed postheating
After starting the engine, the plugs are
supplied simultaneously for a period of 10
seconds.
b) Variable postheating
Variable postheating begins when fixed
postheating ends. The time during which
the plugs are fed (continuously) depends
upon :
- the coolant temperature
- the engine speed ,
- the load (load potentiometer on pump
lever ).
Maximum preheating limit (battery vol-
tage lower than 9.3 volts and altitude hi-
gher than 2 000 m).
Minimum preheating limit (battery
voltage greater than 10.5 volts altitude
lower than 350 m).
