(EN) SPARK PLUG WITH SIDE-MOUNTED GROUND ELECTRODE
(FR) BOUGIE D'ALLUMAGE MUNIE D'UNE ÉLECTRODE DE MASSE PLACÉE LATÉRALEMENT
Abstract
(DE) Die vorliegende Erfindung betrifft eine Zündkerze, umfassend eine Mittelelektrode (3), eine Masseelektrode (2), welche seitlich an der Mittelelektrode (3) angestellt ist, und eine Edelmetalleinlage (31), welche an der Mittelelektrode (3) angeordnet ist, wobei die Edelmetalleinlage (31) in einer in einem Basismaterial (30) der Mittelelektrode (3) vorgesehenen Ausnehmung (5) angeordnet ist und stoffschlüssig mit dem Basismaterial (30) der Mittelelektrode (3) verbunden ist, wobei die Edelmetalleinlage (31) mit einer Oberfläche (33) zur seitlich angestellten Masseelektrode (2) gerichtet ist.
(EN) The present invention relates to a spark plug, comprising a central electrode (3), a ground electrode (2), which is mounted laterally on the central electrode (3), and a noble metal insert (31), which is arranged on the central electrode (3), wherein the noble metal insert (31) is arranged in a cutout (5) provided in a base material (30) of the central electrode (3) and is cohesively connected to the base material (30) of the central electrode (3), wherein the noble metal insert (31) is directed with a surface (33) towards the laterally mounted ground electrode (2).
(FR) L'invention concerne une bougie d'allumage, comprenant une électrode centrale (3), une électrode de masse (2), qui est placée sur un côté de l'électrode centrale (3), et un insert en métal noble (31), qui est disposé sur l'électrode centrale (3), l'insert en métal noble (31) étant disposé dans un évidement (5) ménagé dans un matériau de base (30) de l'électrode centrale (3) et étant relié par liaison de matière au matériau de base (30) de l'électrode centrale (3), une surface (33) de l'insert en métal noble (31) étant tournée vers l'électrode de masse (2) placée latéralement.
