FUEL SUPPLY / IGNITION
1.2 versions
Integrated electronic injection and
ignition system: a single electronic
control unit controls both functions.
It processes both the time the injec-
tion lasts (for fuel metering) and the
spark advance angle.
– Type: ......................Multi-point.
– Method of measuring the amount
of aspirated air for petrol metering:
“Speed density” (*).
– “Closed loop”: information on
combustion for correct petrol meter-
ing achieved by means of two lambda
sensors (one upstream and the other
downstream with respect to the catal-
yser).– Electric petrol pump: in-tank.
– Injection pressure: ......... 3.5 bar.
– Air cleaner: dry-type with paper
filter element.
– Firing order: ................1-3-4-2.
– Engine idling speed: 750±50 rpm.
– Spark plugs:

(*) Analytic method, by electronically process-
ing data from the engine rpm (speed) sensor
and from the air temperature and absolute pres-
sure sensors in the intake manifold (density).
LUBRICATION
Forced-fed with gear pump with
pressure relief valve incorporated.
Oil purification through full-flow
cartridge filter.
COOLING
Cooling system with radiator, cen-
trifugal pump and expansion tank.
“Fixed by-pass” thermostat(1.2 en-
gine)” on the secondary circuit for the
recirculation of water from the engine
to the radiator.
Electric fan for radiator cooling on
the radiator with switching on/off
controlled by thermostatic switch lo-
cated on the radiator. Modifications or repairs
to the fuel feed system that
are not carried out prop-
erly or do not take the system’s
technical specifications into ac-
count can cause malfunctions with
the risk of fire.
