Abstract

Zündkerze mit einem Körper, einer Mittelelektrode und einer Körperelektrode, die dazwischen einen Entladungsspalt für den Zündfunken bilden. Mittel- und Körperelektrode weisen Edelmetallarmierungen auf, die so ausgebildet sind oder werden, dass die Edelmetallflächen eine Überdeckung von wenigstens 90 % aufweisen. Verfahren zur Herstellung einer derartigen Zündkerze.A spark plug having a body, a center electrode and a body electrode defining therebetween a spark discharge gap. Center and body electrodes have noble metal reinforcements that are or are formed so that the noble metal surfaces have a coverage of at least 90%. Method for producing such a spark plug.
