equipped with a breakerless dual capacitor discharge ignition unit with
integrated generator.
The engine 447 UL SCDI is equipped with a breakerless, single capacitor
discharge ignition unit with integrated generator.
The ignition unit is completely free of maintenance and needs no external
power supply.
Two charging coils fitted on the generator stator and independant from
each other feed one each ignition circuit. The energy supplied is stored in
the ignition capacitor. At the moment of ignition the external triggers supply
an impulse to the control circuits and the ignition capacitors are discharged
via the primary winding of the ignition coil. The secondary winding supplies
the high voltage for the ignition spark.
◆ NOTE: The grey cable is planned for a rev-counter signal.
