Abstract:
A system and method of managing the energy stored in a single ignition coil of a distributor inductive ignition for an engine. The engine comprises a plurality of cylinders and the ignition coil has a primary coil current. The ignition coil has a stored energy and a released energy during an ignition period. A pre-dwell time period and a pre-dwell current level is determined. The stored energy of the ignition coil and the released energy of the ignition coil are balanced during the ignition period at least in part by dwelling the primary coil current in the ignition coil at substantially the pre-dwell current level.
