Abstract

A spark plug, and associated systems, for an internal combustion engine includes a central electrode that terminates at a first distal end surface defined about a central axis. The spark plug also includes at least one outer electrode that terminates at a second distal end surface. The at least one outer electrode at least partially laterally surrounds the central electrode such that the second distal end surface is radially offset relative to the central electrode and a lateral gap is defined between the central electrode and the at least one outer electrode. The spark plug include features that force or redirect movement of the flow of the fresh air-fuel mixture through the lateral gap to help to purge or move the residual exhaust gases left over from a previous combustion event out of the lateral gap.
