Abstract
A circuit board for an ignition coil in an internal combustion engine is provided. The ignition coil is in electrical connection with a control module and a spark plug having a pair of gap posts. The ignition coil includes a primary winding having an electrical current, a secondary winding in electrical connection with the spark plug and configured to induce a second electrical current between the gap posts, and an ionization current sensing integrated circuit configured to generate an ionization signal based on the secondary current between the gap posts. The ignition coil also includes a circuit board having an ionization connection in electrical connection with the secondary winding and with the ionization current sensing integrated circuit.
