Zündkerze für Explosionskraftmaschinen. Patentiert im Deutschen Reiche vom 3. Juni 1905 ab. Spark plug for explosion engines. Patented in the German Empire on June 3, 1905.
Bisher wurden die Elektroden der Zündkerzen, wie solche zur Entzündung explosiver Gasgemische für Explosionskraftmaschinen verwandt werden, ausschließlich aus Metall hergestellt.Heretofore, the electrodes of spark plugs, such as those used for ignition, have become more explosive Gas mixtures for explosion engines are used, made exclusively of metal manufactured.
Wird als Metall nicht Platin verwandt, was mit Rücksicht auf den hohen Preis des Platins nicht immer möglich ist, so hat sich stets in mehr oder weniger starkem MaßeThe metal used is not platinum, which is due to the high price of the Platinum is not always possible, so has always been to a greater or lesser extent
ίο ein Übelstand bemerkbar gemacht, der durch die Oxydation der als Elektroden verwandten Metalle hervorgerufen wird. Die Oxyde vereinigen sich mit den im Zylinder vorhandenen Verbrennungsrückständen und dem Schmieröl zu einer an den Elektroden fest haftenden, die Elektrizität leitenden Kruste, die so lange wächst, bis sich zwischen den Elektroden eine leitende Brücke bildet und das Überspringen von Zündungsfunken aufhört, also die Zündkerze versagt.ίο an evil made noticeable by the oxidation of the metals used as electrodes is caused. The oxides combine with the combustion residues in the cylinder and the lubricating oil to form a firmly adhering to the electrodes, the electricity-conducting crust, which grows until there is a forms a conductive bridge and the ignition sparks stop jumping over, i.e. the spark plug fails.
Um diesen Ubelstand zu vermeiden, werden nach dem hier- zu beschreibenden Verfahren die Elektroden aus Graphit oder Kohle oder einem Gemisch von Graphit und Kohle hergestellt.In order to avoid this Ubelstand, according to the procedure to be described here the electrodes are made of graphite or carbon or a mixture of graphite and carbon.
Da die Oxyde des Kohlenstoffs gasförmig sind, so kann sich keine Oxydschicht wie bei Verwendung von Metallelektroden bilden. Bei Verwendung von Graphit allein ist bei den in den Zylindern der Explosionsmotoren vorkommenden Temperaturen eine Oxydation überhaupt ausgeschlossen. Da jedoch leicht eine Absonderung von Kohlenstoff aus denSince the oxides of carbon are gaseous, there can be no oxide layer as in Form using metal electrodes. When using graphite alone is at The temperatures occurring in the cylinders of the explosion engines cause oxidation excluded at all. However, since carbon is easily released from the
