Abstract

A spark plug having a longitudinal axis. The spark plug includes: a housing having a bore along the spark plug longitudinal axis and a combustion-chamber-side end face; an insulator arranged at least partially within the housing, and having an insulator base extending from a combustion-chamber-side end face of the insulator to an insulator base neck; a central electrode arranged at least partially within the insulator; and a ground electrode arranged on the housing, the ground electrode and the central electrode being arranged so that the at least one ground electrode forms a spark gap with the central electrode, a width of the spark gap being defined by an inter-electrode distance between the central electrode and the ground electrode. The inter-electrode distance between the central electrode and the ground electrode is not greater than 0.4 mm. The spark gap is formed at least partially within the housing.
