ABSTRACT:
An ignition system for an internal combustion engine, wherein separate ignition transformers are mounted directly on respective spark plugs and an A.C. drive signal is applied to the ignition transformers sequentially in accordance with engine timing to fire the spark plugs sequentially. The A.C. drive signal is applied to each of the ignition transformers by means of a leakage transformer whereby ignition currents are maintained at a relatively low level after initiation of the ignition discharge across the spark plug electrodes. In one embodiment, each ignition transformer is composed of plural individual transformers disposed in a planetary arrangement around an axis defined by the respective spark plug. Each of these individual transformers includes at least one secondary winding and at least one primary winding wound on a respective core, with each of the secondary windings mounted in series across the electrodes of the spark plug.
