ABSTRACT:
A multiple spark pattern internal combustion initiation device includes a body defining a prechamber and a plurality of orifices from the prechamber. The device includes at least two electrical circuits which each form a spark gap with an electrical ground inside the prechamber, operable to create a plurality of different spark patterns. The device may be part of an internal combustion engine which includes a housing with a combustion chamber connected to the prechamber, and means for supplying a lean gaseous fuel mixture into the combustion chamber.
