ABSTRACT:
An improved high energy high efficiency hybrid capacitive/inductive ignition system with one or coils Ti for internal combustion engines employing one or more energy storage capacitor means (4) shunted by diode means (9), with high leakage inductor means (3a) of coils Ti with which have their primary (1a) and secondary (1b) windings wound side-by-side on a single segmented bobbin 72, unidirectional switches Si for each coil Ti which are preferably IGBTs, and high efficiency shunt diode/switch means SDi for each coil Ti shunting the primary winding of each coil Ti, so that, following production of an initial quarter cycle capacitive spark with peak current in the 0.2 to 3 amp arc discharge range, there is a decaying inductive unidirectional flow-resistant spark flowing through shunt switch means SDi.
