ABSTRACT:
Ignition drive circuitry for generating sequential first and second arcs across electrodes of spark plugs in internal combustion engine cylinders for contributing supplemental combustion energy and for enabling simple, robust misfire detection with a first arc generated through rapid discharge of a storage element and the second arc generated through interruption of said discharge through a transformer primary ignition coil.
