Abstract:
A spark plug is disclosed that includes at least one bore extending through a shell of the spark plug in order to form a passageway between an annular volume around the spark plug insulator nose and a pre-chamber volume of a pre-chamber device, thus directing a purge of exhaust gases trapped in the annular volume to a space formed by the exterior of the spark plug body and the interior of the pre-chamber device.
