Original Abstract Submitted
A spark plug having a longitudinal axis. The spark plug includes: a housing; an insulator disposed at least partly inside the housing; a center electrode disposed at least partly inside the insulator and has an electrode body and an ignition element that is disposed on the combustion chamber-side end of the electrode body and serves as an ignition surface, wherein the ignition element has a cylindrical shape with a round base and a longitudinal axis which extends parallel to the spark plug longitudinal axis; and at least one ground electrode having an ignition surface disposed inside the housing on the housing. The ground electrode and the center electrode are disposed such that they form a spark gap that extends radially with respect to the spark plug longitudinal axis, wherein a width of the spark gap is not greater than 0.3 mm. The spark gaps are completely inside the housing.
