ABSTRACT:
A Kettering type ignition system is improved by modulating the transient output from such system with an AC component signal to substantially increase the energy delivered to the igniters. The system provides for impedance matching of the AC source to the impedance of the ignition transformer. Ignition transformers with single and multiple primary windings are utilized.
