WebThe start of the detonation cycle begins with a non-detonation firing event. The spark plug creates a spark at the moment the ECU signals, or the mechanical distributor causes, the ignition to fire. This moment occurs at a calculated or mechanically set point when the piston is still compressing the air : fuel mixture (on the upward stroke). WebThe spark plug gap widens bit by bit as the electrode wears, so high discharge voltage becomes necessary and misfire occurs more easily. Electrode shape Even for the same spark plug gap, if there are edges on the electrode, discharge occurs more easily.
