Abstract

Die Erfindung betrifft eine Brennkraftmaschine mitThe invention relates to an internal combustion engine with

- mindestens einem Zylinderkopf (1),
- mindestens einem mit dem mindestens einen Zylinderkopf (1) verbindbaren und als obere Kurbelgehäusehälfte dienenden Zylinderblock zur Aufnahme einer Kurbelwelle in mindestens zwei Lagern, und
- einer Pumpe zur Förderung von Motoröl (3) zu den mindestens zwei Lagern, wobei die Pumpe via Versorgungsleitung (2) eine Hauptölgalerie, von der Kanäle zu den mindestens zwei Lagern führen, mit Motoröl (3) versorgt.at least one cylinder head (1),
- At least one with the at least one cylinder head (1) connectable and serving as the upper crankcase half cylinder block for receiving a crankshaft in at least two bearings, and
- A pump for delivering engine oil (3) to the at least two bearings, wherein the pump via supply line (2) a main oil gallery, supplied by the channels to the at least two camps, with engine oil (3).

Des Weiteren betrifft die Erfindung ein Verfahren zur Erwärmung des Motoröls (3) einer derartigen Brennkraftmaschine.Furthermore, the invention relates to a method for heating the engine oil (3) of such an internal combustion engine.

Es soll eine Brennkraftmaschine bereitgestellt werden, die hinsichtlich der Reibleistung optimiert ist.It should be provided an internal combustion engine, which is optimized in terms of friction.

Erreicht wird dies mit einer Brennkraftmaschine der genannten Art, die dadurch gekennzeichnet ist, dass die Versorgungsleitung (2) stromaufwärts der Hauptölgalerie durch den Zylinderkopf (1) hindurchführt.

Figure imgaf001
This is achieved with an internal combustion engine of the type mentioned, which is characterized in that the supply line (2) passes upstream of the main oil gallery through the cylinder head (1).
