Patent ID: 6882259

Claim:
An ignition coil for an internal combustion engine, the ignition coil in electrical connection with a control module, an electrical power supply, and a spark plug having a pair of gap posts, the ignition coil comprising: a primary winding in electrical connection with the electrical power supply such that an electrical current travels through the primary winding; a secondary winding located adjacent to the primary winding and in electrical connection with the spark plug, the secondary winding inducing a second electrical current between the pair of gap posts based on the electrical current traveling through the primary winding, and the secondary winding including an upstanding pin and; an ionization current sensing integrated (ICSI) circuit in electrical connection with the secondary winding via an ionization connection, the ICSI circuit configured to generate an ionization signal based on the second electrical current between the pair of gap posts, the ICSI circuit including an upstanding pin; and a circuit board having a secondary winding opening and an ICSI circuit opening, the circuit board being positioned such that the upstanding pin of the secondary winding extends through the secondary winding opening and the upstanding pin of the ICSI circuit extends through the ICSI circuit opening in order to form the ionization connection.
