Abstract: An ignition system for an internal combustion engine has a power source, a transformer having a first primary winding and a second primary winding and a secondary winding, a connector extending from the secondary winding so as to connect with a terminal of a spark plug, and a multi-strike circuit cooperative with the electronic spark timing circuit so as to fire the transformer with multiple strikes between the falling edge and the rising edge. A booster circuit is cooperative at the electronic spark timing circuit so as to collect and store energy from the power source while the electronic spark timing circuit fires the transformer. A delay circuit fires the transformer at a time subsequent to the falling edge and before the rising edge.

Abstract: An ignition coil has a ferromagnetic core, a primary coil surrounding a portion of the core and wrapped helically with a conductor, a winding form having partitions extending outwardly of a tubular surface of the winding form, and a secondary coil wrapped on the winding form.

The secondary coil includes coil sections in each of the plurality of coil chambers. The secondary coil has coil turns in the end chambers in a spiral configuration on the spiral land and increasing progressively in diameter toward the central chambers.

Abstract: A method of firing a spark plug of an internal combustion engine includes supplying AC power to the spark plug in which the AC power has a waveform with a rising edge and a falling edge, activating the spark plug during the rising edge of the waveform, and deactivating the spark plug during the falling edge of the waveform. This method further includes connecting an engine control module to an ignition coil and connecting the engine coil to the spark plug. The firing of the ignition coil mirrors the square waveform of AC power from the engine control module. A battery is connected to the engine control module.
