ABSTRACT:
An IC engine spark plug wherein the gap-defining end of the ground electrode is split or divided to form two continuously diverging non-parallel angularly spaced apart end portions, the base or vertex region where the end portions join together being so located relative to the plug's center electrode that a spark bridging the plug's spark gap impinges first at the base region and then splits for simultaneous travel along the end portions.
