INJECTION TIME COMPENSATION
The various sensors allow the injection time (volume) compensations to be carried out on the basis of the following
signals.
SIGNAL
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.
When the atmospheric pressure is low, the sensor
sends a signal to the ECU to reduce the injection
time (volume of the fuel injected) to compensate
the lower presence of oxygen in the atmosphere.
ENGINE COOLANT TEMPERATURE SENSOR
SIGNAL
When the temperature of the engine coolant is low,
the injection time (volume) is increased to sustain
the minimum r.p.m. and to compensate the part of
the fuel which condensates along the intake con-
duits.
AIR INTAKE TEMPERATURE SENSOR SIGNAL
When the temperature of the intake air is low, the
injection time (volume) is increased to compensate
the higher presence of oxygen.
BATTERY VOLTAGE SIGNAL
The battery voltage signal is supplied to the ECU for
the functioning of the ECU and this voltage is revea-
led and utilised as a signal for the compensation of
the injection time (volume). A low voltage determi-
nes a longer injection time for 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, during craking a
greater volume of fuel is injectedto make starting
easier.
