ELECTRONIC IGNITION SYSTEM
The ignition system is controlled by the ECU. The system belongs to the category of the integrated systems of digital electronic ignition with
advance and static distribution and gasoline electronic injection of intermittent sequential balanced type. This ignition system consists of a sensor
of the crankshaft position (Pick-up), an ECU, an ignition coil and an air pressure sensor of the intake manifold. The feeding of the ignition coil is
supplied by the battery with a power relay and is controlled by the ECU. The synchronization of the ignition is checked with precision with regard
to the engine r.p.m. and the position of the throttle control. Besides this basic condition, also the temperature and air pressure sensors and the
coolant temperature influence the synchronization of the ignition.
