Abstract

Es wird eine Zündkerze (1) für eine Brennkraftmaschine mit einem Gehäuse (2), das mit einem Außengewinde (4) zum Einschrauben in einen Zylinderkopf und einer kegelstumpfartig oder eben ausgeführten Dichtfläche (7) zum Abdichten eines Brennraums der Brennkraftmaschine ausgebildet ist, beschrieben. Die Dichtfläche (7) wirkt mit einem Dichtsitz des Zylinderkopfes zusammen. Das Gehäuse (2) ist zusätzlich mit einem Bereich ausgeführt, der als Angriffsbereich (3) für ein Montagewerkzeug ausgebildet ist. Eine Außenkontur des Angriffsbereichs (3) ist als Vieleck ausgeführt und eine Eckenanzahl des Angriffsbereichs (3) ist wenigstens 12.There is described a spark plug (1) for an internal combustion engine having a housing (2) formed with an external thread (4) for screwing into a cylinder head and a frusto-conical or flat sealing surface (7) for sealing a combustion chamber of the internal combustion engine. The sealing surface (7) cooperates with a sealing seat of the cylinder head. The housing (2) is additionally designed with a region which is designed as an engagement region (3) for an assembly tool. An outer contour of the engagement area (3) is designed as a polygon and a number of corners of the attack area (3) is at least 12.
