Weitere wichtige Merkmale und Vorteile ergeben sich aus den Unteransprüchen, aus den Zeichnungen und aus der nachfolgenden Beschreibung eines bevorzugten Ausführungsbeispiels anhand der Zeichnungen. Es zeigen:Other important features and advantages will become apparent from the subclaims, from the drawings and from the following description of a preferred embodiment with reference to the drawings. Show it:

1 eine schematische Darstellung der Brennkraftmaschine 1 a schematic representation of the internal combustion engine

2 eine schematische Darstellung Wasserpumpe mit integriertem Verteiler 2 a schematic representation of water pump with integrated distributor

In 1 wird schematisch eine Brennkraftmaschine mit einem Zylinderkurbelgehäuse 1 gezeigt, in dem eine Kurbelwelle drehbar gelagert ist, an der zumindest ein einen Kolben tragendes Pleuel angelenkt ist, wobei der Kolben in einen von einem Zylinderkopf 2 abgedeckten Zylinder bewegbar ist und wobei von der Kurbelwelle eine in einem frontseitig an dem Zylinderkurbelgehäuse 1 montierten und zumindest einen integrierten Kanal für Kühlwasser aufweisende Wasserpumpe mit integriertem Verteiler 3 mittels eines Riemens angetrieben ist, wobei die Wasserpumpe 3 im Wesentlichen an einer Frontseite der Brennkraftmaschine angeordnet ist und der Kanal in Strömungsverbindung mit einem AGR-Kühler 6 steht. Ein weiterer integrierter Kanal versorgt im Wesentlichen parallel den Motorölkühler 4 und das Zylinderkurbelgehäuse 1 mit Kühlwasser, um sich in Strömungsrichtung noch vor dem Zylinderkopf 2 mit dem Kühlwasserrücklauf aus dem AGR-Kühler 6 zu vereinen. Der vereinigte Kühlwasserstrom durchströmt anschließend den Zylinderkopf 2, um dann den Motorwasserkühler 5 zu durchströmen. Nachdem der Kühlwasserstrom den Motorwasserkühler 5 durchströmt hat, gelangt das Kühlwasser wieder in den Einlassbereich von Wasserpumpe 3.In 1 schematically is an internal combustion engine with a cylinder crankcase 1 shown, in which a crankshaft is rotatably mounted, on which at least one piston carrying a connecting rod is articulated, wherein the piston in one of a cylinder head 2 covered cylinder is movable and wherein the crankshaft in a front of the cylinder crankcase 1 mounted and at least one integrated channel for cooling water having water pump with integrated distributor 3 is driven by a belt, the water pump 3 is disposed substantially on a front side of the internal combustion engine and the channel in fluid communication with an EGR cooler 6 stands. Another integrated channel essentially supplies the engine oil cooler in parallel 4 and the cylinder crankcase 1 with cooling water to flow in front of the cylinder head 2 with the cooling water return from the EGR cooler 6 to unite. The combined cooling water flow then flows through the cylinder head 2 and then the engine water cooler 5 to flow through. After the cooling water flow the engine water cooler 5 has passed through the cooling water back into the inlet region of the water pump 3 ,

2 stellt schematisch die Wasserpumpe mit integriertem Verteiler 3 dar. Der integrierte Verteiler 10 besteht aus dem Kanal zum ZKG 8 und Kanal zum AGR 7. Des Weiteren umfasst die Wasserpumpe 3 den Einlassbereich 9 der Wasserpumpe bzw. den Rücklauf vom Motorwasserkühler. 2 schematically shows the water pump with integrated distributor 3 dar. The integrated distributor 10 consists of the channel to the CCG 8th and channel to the EGR 7 , Furthermore, the water pump includes 3 the inlet area 9 the water pump or the return from the engine water cooler.
