ABSTRACT:
This electronic ignition system comprises a unique combination of a high voltage switching regulator to provide substantially higher voltage to the ignition coil and a solid state power switch to produce a constant high energy ignition current of multiple repetitions for a selected duration dependent upon engine speed. The power switch is controlled by a pulser and a window generator which respond to virtually any available trigger source including conventional breaker points and generates an engine speed dependent window signal the duration of which defines the ignition energy characteristics.
