Description

Zündkerze, insbesondere für hochkomprimierte Verbrennungsmotoren Bei Zündkerzen, die in hochkomprimierten Motoren verwendet werden, ist es üblich, eine Elektrode aus hochwertigem .Material, wie Platin, zu verwenden, die an dem Mittelstift der Kerze befestigt ist. Die Elektrode wurde bei den bekannten Ausführungen an dem Mittelstift festgenietet und außerdem noch mit Silberlot gelötet. Es hat sich gezeigt, daß Silberlot den in hochkomprimierten Motoren auftretenden Temperaturen auf die Dauer nicht standhält und deshalb die Elektrode sich lockert. Dieser Nachteil tritt nicht ein bei Elektroden, die gemäß der Erfindung mit einem Lot aus Gold und Nickel gelötet sind.Spark plug, especially for highly compressed internal combustion engines Spark plugs, which are used in high-compression engines, it is common to have one Electrode made of high quality material, such as platinum, to be used on the center pin the candle is attached. The electrode was in the known designs on the Center pin riveted and also soldered with silver solder. It has shown, that silver solder to the temperatures occurring in highly compressed engines Does not last for a long time and therefore the electrode loosens. This disadvantage occurs not one in the case of electrodes made according to the invention with a solder made of gold and nickel are soldered.

In der Abbildung ist als Ausführungsbeispiel der Erfindung eine Zündkerze dargestellt. a ist ein Kerzenkörper, in dem ein Isolierkörper b mittels einer Überwurfmutter c festgehalten ist. In dem Isolierkörper b sitzt ein Mittelstift d, der an einem Ende als Kabelanschlußstück e ausgebildet ist, während an seinem anderen Ende ein Platinplättchen f aufgenietet und mit Goldlot g mit dem Stift d verlötet ist. Auf der Stirnseite des Kerzenkörpers sind Masseelektroden h in bekannter Weise angeordnet. Als ein für den vorliegenden Zweck besonders bewährtes Goldlot hat sich ein solches aus 5o bis 6o °j, Gold und 4.o bis 50 °[o Nickel gezeigt.In the figure is a spark plug as an embodiment of the invention shown. a is a plug body in which an insulating body b by means of a union nut c is recorded. In the insulating body b sits a center pin d on a End is designed as a cable connector e, while at its other end a Platinum plate f is riveted on and soldered to pin d with gold solder g. on ground electrodes h are arranged in a known manner on the end face of the plug body. Such a gold solder has proven to be a particularly well-proven gold solder for the present purpose shown from 50 to 60 degrees, gold and 4.o to 50 degrees nickel.
