Injection
11
The combined ignition/injection system is a high-efficiency induction system.
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 engine at idle speed, it is optimised to stabilise the speed at 1450 ± 50 rpm. - Magnetisation time
The coil magnetisation time is controlled by the control unit. The power of the ignition is increased during
the engine start-up phase.
The injection system recognises the 4-stroke cycle so ignition is only commanded in the compression
phase.
Specific tooling
* Digital multimeter
Check that the 20A main fuse No. 2 and the injection load 15A No. 4 fuse are in good conditions.
Check there is voltage between pins 22 and 26 of
the interface wiring for around two seconds upon
switching to "ON"
Check the resistance of the coil primary between
pin 22 of the interface wiring and the Red-Brown
cable of the injection relay, with both the control
unit and the remote control disconnected.
Primary resistance = 0.5 ± 8% Ohm
Specification
Electric fan remote control
