Abstract

Die vorliegende Erfindung betrifft eine Verbrennungskraftmaschine, der eine Kraftstoffpumpe (63,65,67) zugeordnet ist. Weiterhin betrifft die vorliegende Erfindung ein Betriebsverfahren einer entsprechenden Verbrennungskraftmaschine mit Kraftstoffpumpe (63,65,67). Die Kurbelwelle (35) einer solchen Verbrennungskraftmaschine, genauer die Kurbelwellenwange (37), treibt unmittelbar - ohne Zwischenelement - ein Antriebsglied (81) der Kraftstoffpumpe (63,65,67) an. Die in der Rotation der Kurbelwellenwange (37) vorhandene Antriebsenergie wird direkt auf die Kraftstoffpumpe (63,65,67) weitergegeben. Es gibt eine Berührungslinie zwischen Kurbelwelle (35) und Antriebsglied (81) der Kraftstoffpumpe (63,65,67).

The present invention relates to an internal combustion engine associated with a fuel pump (63, 65, 67). Furthermore, the present invention relates to an operating method of a corresponding internal combustion engine with fuel pump (63,65,67). The crankshaft (35) of such an internal combustion engine, more precisely the crankshaft web (37), drives directly - without intermediate element - a drive member (81) of the fuel pump (63,65,67). The drive energy present in the rotation of the crankshaft cheek (37) is transmitted directly to the fuel pump (63, 65, 67). There is a line of contact between crankshaft (35) and drive member (81) of the fuel pump (63, 65, 67).
