CA 2134816
An engine ignition and control system for an internal combustion engine. The system includes an ignition transformer mounted to a spark plug and adapted to rapidly re-fire the spark plug during a combustion cycle enabling the performance of various engine diagnostic procedures. A controller provides a signal to an ignition circuit which causes the transformer to charge for ignition and subsequently charge for performing diagnostics. The system also includes a diagnostic circuit, connected to the transformer, which can detect the occurrence of an electrical discharge across the spark plug electrodes as a result of one of the diagnostic charges. The detections circuit either outputs a signal to the controller or omits the signal to the controller. This allows the controller to diagnose conditions within the combustion cylinder.
