Electronic Breakerless Inductive Storage Ignition

To improve engine performance, reduce air pollution, and increase spark plug life, electronic ignition redesign may be necessary. This report covers the advantages and some of the practical limitations that can be involved in electronic breakerless inductive storage ignition design. Basic principles such as dwell control are examined in detail. Specific conclusions regarding Darlington coil-switching transistors and current-limiting vari-dwell ignition circuits are drawn.
