ABSTRACT:
A breakerless distributor for an internal combustion engine ignition system in which a number of light emitting diodes (LEDs) (73, 75, 77, 79) equal to the number of engine cylinders are connected in series for simultaneous energization by the timing pulses. A phototransistor (83, 85, 87, 89) arranged in spaced, confronting relationship to each LED is connected to a silicon controlled rectifier (95) which triggers the energizing circuit (7, 9, 11, 13) for an individual spark plug (103) each time the phototransistor is turned on by emissions from its associated LED.
