ABSTRACT:
In a spark plug with combined surface and air spark paths comprising a center electrode, and insulator which surrounds the center electrode and which, at least in the end region of the center electrode, maintains a gap with respect thereto, and a ground electrode which, together with the spark plug body, surrounds the insulator and which at least in the end region of the insulator maintains a gap with respect thereto, the insulator, to form a discharge chamber surrounding the end portion of the center electrode, extends in the axial direction of the plug beyond the center electrode, and the ground electrode encompasses the insulator around the end thereof with an extension of the ground electrode extending into the discharge chamber with a clearance gap being maintained between the extension and the end portion of the insulator.
