摘要: In a spark plug having a cylindrical metal shell having a ground electrode; an insulator fixedly supported within the metal shell with a front end of the insulator extended beyond a front end of the metal shell, the insulator having an axial bore in which a center electrode is placed to form a spark gap with the ground electrode, the front end of the metal shell is adapted to be generally in flush with or somewhat inward into an inner wall of a combustion chamber of an internal combustion engine when the spark plug is mounted on a cylinder head of the internal combustion engine. The front end of the insulator extends at least 4.0 mm from the front end of the metal shell.
