Abstract
In the ignition system two capacitors (10 ,11) are charged from an alternator (14) through a diode network (12,13). Alternate half cycles charge alternate capacitors. In series with each capacitor is a thyristor (18,19) with cathodes connected to one end of the induction coil's prim. winding (15a). In response to a signal from the timing circuit (20-25) both thyristors are triggered into conduction simultaneously and discharge the capacitors into the induction coil to break over the sparking plug (17). The proposed circuit utilises both positive and negative half voltage waves from the generator, and enables a higher effective energy discharge into the coil. The thyristors are positively turned off at the end of each conduction period.
