Abstract
A method of ion sensing in a CD ignition system for an internal combustion engine comprises: a) closing the controllable switch in synchronism with the internal combustion engine for a period of time to transfer energy to the ignition coil primary to cause a spark breakdown across the spark plug; and b) observing the current in the secondary winding circuit indicative of ionization in the vicinity of the spark plug electrodes.
