ABSTRACT:
In a first operative mode, the control unit first causes energy to be stored by the inductor and then connects the inductor to the capacitor so as to form a resonance circuit whose energy is discharged into the primary winding of the coil in order to generate a spark. In a second operative mode, the unit causes a plurality of cycles to be effected to charge the capacitor so as to increase the voltage across its terminals at each cycle and the capacitor is then discharged into the primary winding of the ignition coil in order to generate the spark.
