Abstract: An ignition coil for delivering a spark-generating current to a spark plug includes a magnetically-permeable core; a primary winding disposed outward of the core; and a secondary winding radially surrounding the primary winding and inductively coupled to the primary winding, the secondary winding having a low-voltage end and a high-voltage end. The secondary winding includes a secondary winding first section proximal to the low-voltage end and having a first thickness. The secondary winding also includes a secondary winding second section proximal to the high-voltage end and having a second thickness that is less than the first thickness of the secondary winding first section.

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.

Abstract: An ignition coil for delivering a spark-generating current to a spark plug includes a magnetically-permeable core; a primary winding disposed outward of the core; and a secondary winding disposed outward of the primary winding and inductively coupled to the primary winding. The secondary winding terminates at one end thereof in a low-voltage end and terminates at another end thereof in a high-voltage end. At least one of the low-voltage end of the secondary winding and the high-voltage end of the secondary winding is electrically connected directly to a terminal through an electrically conductive polymer.

Abstract: An ignition coil includes a magnetically-permeable core, a primary winding disposed outward of the core, and a secondary winding disposed outward of the primary winding and inductively coupled to the primary winding. The secondary winding includes a left secondary winding section wound clockwise around the primary winding and a right winding section wound counterclockwise around the primary winding. The left secondary winding section has i) a first left winding end distal from the right winding section and ii) a second left winding end that is proximal to the right winding section. The right secondary winding section has i) a first right winding end distal from the left winding section and ii) a second right winding end that is proximal to the left winding section. The second left winding end and the second right winding end are connected to a terminal.
