Abstract:
1. An internal combustion engine igniter comprising a spark plug with an electrically neutral intermediate electrode that is both physically and electrically insulated from a spark plug's center electrode and ground strap electrode, wherein said intermediate electrode is positioned between said spark plug's center electrode and ground strap electrode forming a spark air gap between said intermediate electrode and the spark plug's center electrode and another spark air gap between said intermediate electrode and the ground strap electrode, wherein the spark plug produces two independent ignition sparks for each and every single electrical discharge of an ignition coil, wherein the intermediate electrode is affixed to a spark plug's center electrode insulator, wherein said intermediate electrode is structurally supported by the spark plug's said center electrode insulator for rigid positioning and configured so that different configurations and shapes of said intermediate electrode is physically and electrically disposed between the spark plug's center electrode and ground strap electrode, wherein said intermediate electrode as positioned forms a spark air gap between the spark plug's center electrode and said intermediate electrode and another spark air gap between the ground strap electrode and said intermediate electrode thereby providing an electrical conduction path for two distinct and separate ignition sparks in electrical series for each single electrical discharge of an ignition coil.
