ABSTRACT Capacitor discharge ignition system for a spark- ignition internal combustion engine. The ignition system employs an ignition coil having primary and secondary windings would on a ferromagnetic core, preferably made of a ferrite material. A first capacitor is connected in series with a spark gap and this series combination is connected across the ignition coil secondary winding. The ignition coil primary winding has a second capacitor coupled to it which capacitor is charged and then discharged in timed relation to engine operation. The first capacitor and ignition coil windings and construction are selected such that the second capacitor when discharged through the ignition coil primary winding produces ferroresonant oscillations in the secondary circuit of the ignition coil. This breaks down the spark gap and an alternating voltage, at the ferroresonant frequency, occurs. The ignition system has fast rise time of the voltage across the spark gap, long duration of the spark and preferably includes restrike capability.
