Abstract
An ignition system for the internal combustion engine comprising a high voltage circuit for generating a spark, having the primary and secondary windings. In response to a first signal, the current in the primary winding is cut off thereby to generate a high voltage at the secondary winding. In response to a subsequent second signal, the primary winding is shorted thereby to cut off the high voltage thus far generated in the secondary winding, thus properly regulating the duration of the spark generated.
