Abstract
A method for detecting misfire in a cylinder of an internal combustion engine through the ignition system of the engine. The present invention first predicts a time-to-fire measurement for an interrogating spark, then measures the actual time-to-fire measurement of the interrogating spark and then compares the predicted measurement and the actual measurement to determine whether misfire has occurred.
