Abstract

Die vorliegende Erfindung betrifft eine Verbrennungskraftmaschine, der eine Kraftstoffpumpe zugeordnet ist. Weiterhin betrifft die vorliegende Erfindung ein Betriebsverfahren einer entsprechenden Verbrennungskraftmaschine mit Kraftstoffpumpe. Bei Kraftstoffpumpen treten aufgrund des zu erzeugenden hohen Drucks zunehmend Schwierigkeiten auf. Daher wird erfindungsgemäß die Kurbelwelle in die Designbetrachtungen einbezogen. Die Kurbelwelle, genauer der Kurbelwellenschaft, treibt erfindungsgemäß unmittelbar - ohne Zwischenelement - ein Antriebsglied der Kraftstoffpumpe an. Die in der Rotation des Kurbelwellenschafts vorhandene Antriebsenergie wird direkt auf die Kraftstoffpumpe weitergegeben. Es gibt eine Berührungslinie zwischen Kurbelwelle und Antriebsglied der Kraftstoffpumpe. Kurbelwelle und Kraftstoffpumpe lagern gegeneinander, beide Teile, Kurbelwelle und Kraftstoffpumpe, sind im Bereich des Kurbelwellenschafts in Berührkontakt. Diese Art des Antriebs löst viele Probleme, die bei einem Steuertriebantrieb nicht überwunden werden können.

The present invention relates to an internal combustion engine associated with a fuel pump. Furthermore, the present invention relates to an operating method of a corresponding internal combustion engine with a fuel pump. With fuel pumps, difficulties arise due to the high pressure to be generated. Therefore, according to the invention, the crankshaft is included in the design considerations. The crankshaft, more precisely the crankshaft shaft, drives according to the invention directly - without an intermediate element - to a drive member of the fuel pump. The drive energy present in the rotation of the crankshaft shaft is passed on directly to the fuel pump. There is a line of contact between crankshaft and drive member of the fuel pump. Crankshaft and fuel pump bear against each other, both parts, crankshaft and fuel pump, are in contact with each other in the area of the crankshaft shaft. This type of drive solves many problems that can not be overcome with a timing drive drive.
