Abstract

Improvements in spark ignition systems for internal combustion engines, characterized in that the system comprises, in combination, an ignition transformer that has a primary winding and a secondary winding, a transistor that has its collector-emitter path connected in series with the primary winding, the transistor being turned off to produce a spark, and means that limit the base current of the transistor to a degree just enough to keep the transistor at the saturation point.
