Description
Die Erfindung betrifft einen Fluidkreislauf einer Brennkraftmaschine.The invention relates to a fluid circuit of an internal combustion engine.

Nachteilig an derartigen Fluidkreisläufen ist, dass es durch Strömungsablösungen zu unerwünschten Druckverlusten kommen kann, in deren Folge eine erhöhte Pumpenleistung und somit ein höherer Kraftstoffverbrauch entstehen.A disadvantage of such fluid circuits is that the flow separation can lead to undesirable pressure losses, as a result of which an increased pump output and thus a higher fuel consumption arise.
Aufgabe der vorliegenden Erfindung ist es, einen Fluidkreislauf zu schaffen, der die oben genannten Nachteile und Druckverluste vermeidet.The object of the present invention is to create a fluid circuit which avoids the above-mentioned disadvantages and pressure losses.
Die Aufgabe wird mittels eines Fluidkreislaufs einer Brennkraftmaschine mit wenigstens einem gegossenen Zylinderblock mit einem Kühlmittelmantel, wenigstens einem Zylinderkopf mit Kühlmittelkanälen, wenigstens einer gemeinsamen Flanschfläche zwischen Zylinderkopf und Zylinderblock sowie mit Kühlmittelführungen und/oder Ölkanalführungen innerhalb des Zylinderblocks gelöst.The object is achieved by means of a fluid circuit of an internal combustion engine with at least one cast cylinder block with a coolant jacket, at least one cylinder head with coolant channels, at least one common flange surface between the cylinder head and cylinder block and with coolant ducts and / or oil ducts within the cylinder block.
Weitere vorteilhafte Ausgestaltungen sind in den Unteransprüchen enthalten.Further advantageous configurations are contained in the subclaims.
