INJECTION TIME COMPENSATION (VOLUME)
The various sensors allow the injection time (volume) compensations to be carried out on the basis of the fol-
lowing signals.

ATMOSPHERIC PRESSURE SENSOR SIGNAL
DESCRIPTION
SIGNAL
INJECTION ARREST CONTROL
DESCRIPTION
R.P.M. LIMITER SIGNAL
The functioning of the fuel injectors is interrupted
when the level of engine r.p.m. reaches its limit. The
r.p.m. limiter interrupts the ignition system and the
interruption signal of the ignition is therefore sent to
the ECU.
When the atmospheric pressure is low, the sensor
sends a signal to the ECU to reduce the injection
time (volume).
En phase de démarrage le même capteur est utilisé
pour aligner l'injectée et la scintille dans les 4 bancs.
ENGINE COOLANT TEMPERATURE SENSOR SIG-
NAL
When the temperature of the engine coolant is low,
the injection time (volume) is increased.
AIR INTAKE TEMPERATURE SENSOR SIGNAL
When the temperature of the intake air is low, the
injection time (volume) is increased.
BATTERY VOLTAGE SIGNAL
The voltage of the battery is supplied to the ECU for
the functioning of the ECU and this voltage is
revealed and utilised as a signal for the compensa-
tion of the injection time (volume). A low voltage
determines a longer injection time for the adjustment
of the volume of the injection.
ACCELERATION/DECELERATION SIGNAL
During acceleration, the injection time of the fuel
(volume) is increased in proportion to the opening of
the accelerator and the r.p.m. of the engine. During
deceleration, the injection of fuel is diminished in
proportion to the speed of closure of the accelerator
handgrip and of the engine r.p.m.
STARTER SIGNAL
When the engine is switched on, a greater volume of
fuel is injected during the starting period.
