Injection
9. Fuel injector
10.Electric fan solenoid
The ignition system is integrated with the injection and it is a high-efficiency inductive type ignition.
The control unit manages two significant parameters:
- Ignition advance
This is optimised at once according to the engine revs, engine load, temperature and ambient pressure.
With idle engine, it is optimised to obtain the stabilisation of the speed at 1450 ± 50 R/1'.
- Magnetisation time
The coil magnetisation time is controlled by the control unit. The ignition power is increased during the
engine start-up phase.
The injection system recognises the four-stroke cycle so the ignition is only commanded in the com-
pression phase.
Specific tooling
020331Y Digital multimeter
Check that the injection load 15A fuse No. 2 works
properly.
Check that the 7.5A fuse No. 5 for live control unit
power works properly.
Check the efficiency of the injection load solenoid.
Check the resistance of the energising coil be-
tween pins 86 and 85: 40 to 80 Ohm
Apply a voltage of 12V to pins 86 and 85; make
sure that there is continuity between pins 30 and
87 of the relay.
