Abstract: An ignition system for an internal combustion engine includes an ignition transformer with two primary windings. The ignition system is designed to generate, for a given ignition event, a unipolar current through the secondary winding by way of a control circuit that is configured to first energize and deenergize the first primary winding to establish a first electrical arc across the spark-plug electrodes and, when the current in the secondary winding reaches, or drops below, a current threshold, repeatedly energizes and deenergizes the second primary winding to establish a plurality of second current pulses across the electrodes in order to maintain the burn phase.

Abstract: An ignition coil system is configured for use with a spark ignition internal combustion engine. The system includes a first switching circuit electrically connected to the primary coil that provides electrical power to the primary coil. The system includes a second switching circuit connected to the primary coil that is configured to short the terminals of the primary coil after the secondary current has been induced in the secondary coil, whereby the secondary coil induces a current in the primary coil, thereby reducing the secondary current in the secondary wire coil. A controller in communication with the first and second switching circuits is configured to receive a single electronic spark timing (EST) signal and to control the conductive states and the non-conductive states of the first and second switching circuits based on this single EST signal.
