ABSTRACT:
An internal combustion engine contactless ignition system of the supply voltage variation compensation type in which the length of time an ignition coil is energized is controlled by an input transistor in response to an alternating current signal synchronized with the rotation of an engine and the operating level of the input transistor is automatically shifted in response to variation of the voltage of a power source, further comprises an inverting transistor having a base connected to the collector of the input transistor, an emitter connected to one end of the power source through a common emitter resistor and a collector connected to the other end of the power source through collector resistors and a Zener diode whereby an ignition coil energization controlling power transistor is controlled through the inverting transistor.
