The ignition system is integrated with the injection and it is a high-efficiency inductive type ignition.
The control unit manages two important parameters:
- Ignition advance
This is optimised at the moment in accordance with the engine revs, engine load, temperature and
environmental pressure.
With the engine at idle, the ignition advance is optimised to stabilise the speed at 1450 ± 50 rpm.
- 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 4-stroke cycle and therefore, ignition is only controlled during
compression.
