ABSTRACT:
An ignition system for a multicylinder internal combustion engine comprising a turn-on signal source for producing a turn-on signal a plurality of times per revolution of the engine output shaft, a plurality of trigger signal sources each producing a trigger signal once per revolution, and a plurality of gate circuits enabled by the trigger signal to permit the application of the turn-on signal to the associated one of a plurality of capacitor discharge ignition circuits. Thus each ignition circuit operates once per revolution. The turn-on signal is produced at angles varying with the engine speed, and various ignition angle characteristics can be obtained.
