Es ist Aufgabe der vorliegenden Erfindung, eine Brennkraftmaschine mit einem minimierten Ölverbrauch und zuverlässigen Langzeiteigenschaften zu schaffen.It Object of the present invention, an internal combustion engine with a minimized oil consumption and reliable To create long-term properties.
Erfindungsgemäß wird diese Aufgabe durch die im Anspruch 1 genannten Merkmale gelöst.According to the invention this Problem solved by the features mentioned in claim 1.
Bei der Verwendung eines Aluminiumwerkstoffs für den Kolben und eines Stahlwerkstoffs für den Kolbenbolzen und der in diesem Zusammenhang eingesetzten Lagerung des Kolbenbolzens über ein Wälzlager in dem Kolben, kann vollständig darauf verzichtet werden, das Öl durch das Pleuel zu dem Kolben zu führen, da dort eine Schmierung nicht mehr notwendig ist.at the use of an aluminum material for the piston and a steel material for the Piston pin and the storage used in this context of the piston pin over a rolling bearing in the piston, can completely on it to be dispensed with, the oil through the connecting rod to the piston, there is a lubrication is no longer necessary.
Die erfindungsgemäße Beschichtung der Kolbennabe des Kolbens mit einem Weichmetall verhindert in einfacher und effektiver Weise die Bildung von Passungsrost zwischen dem Kolbenbolzen und dem Kolben.The coating according to the invention the piston hub of the piston with a soft metal prevents in easier and effectively the formation of fretting corrosion between the piston pin and the piston.
Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen sowie aus dem nachfolgend anhand der Zeichnung prinzipmäßig dargestellten Ausführungsbeispiel.advantageous Refinements and developments of the invention will become apparent the dependent claims as well as from the below in principle with reference to the drawing Embodiment.
