Abstract
In a capacitive discharge ignition system there being a first circuit detecting the voltage across the storage capacitor marking the onset of discharge of the storage capacitor, a second circuit detecting the voltage across the storage capacitor marking the substantially complete discharge of the storage capacitor, a third circuit for measuring the time between the events marked by the first and second circuits, and a fourth circuit for analyzing the measured time to determine conditions in the ignition system.
