ABSTRACT:
An internal combustion engine spark ignition system includes two inductors and a circuit for transferring energy from the inductors to a common spark circuit when current flow through the inductors is interrupted. Two transistors control current flow in the respective inductors and these are controlled by a control circuit which turns on and then off just one of the transistors when a normal spark is required, and which turns on both transistors and then turns these alternately on and off when an extended spark is required.
