Das in Fig. 1 dargestellte Ölauffanggehäuse, im folgenden als Ölwanne 2 bezeichnet, ist im zusammengebauten Zustand mit seiner Flanschfläche 4 an einer Flanschfläche 6 eines Kurbelgehäuseunterteils 8, einem sog. Bedplate, befestigt. Auf der Unterseite des Kurbelgehäuseunterteils 8 ist eine als Doppelpumpe ausgebildete Schmierölpumpe 10 befestigt. In der Ölwanne 2 ist ein erster Ölsammelraum 12 ausgebildet, in dem sich das für die Schmierölversorgung notwenige Öl in einem Ölsumpf ansammelt. Im ersten Ölsammelraum 12 ist ein Ölschnorchel 14 angeordnet, der über eine erste Ölabsaugleitung 16 zu einer Saugseite einer ersten Pumpenstufe der Schmierölpumpe 10 führt. In der Ölwanne 2 ist ein zweiter, hinterer Ölsammelraum 18 ausgebildet, an dessen tiefster Stelle ebenfalls ein Ölschnorchel 20 angeordnet ist, der über eine zweite Ölabsaugleitung 22 mit einer Saugseite einer zweiten Pumpenstufe der Schmierölpumpe 10 verbunden ist. The oil collecting housing shown in Fig. 1, hereinafter referred to as oil pan 2, is in the assembled state with its flange surface 4 on a flange surface 6 Crankcase lower part 8, a so-called bedplate, attached. On the bottom of the The lower crankcase part 8 is a lubricating oil pump 10 designed as a double pump attached. In the oil pan 2, a first oil collecting space 12 is formed, in which the necessary oil for the lubricating oil supply accumulates in an oil sump. In the first Oil collection chamber 12, an oil snorkel 14 is arranged over a first Oil suction line 16 to a suction side of a first pump stage of the lubricating oil pump 10 leads. In the oil pan 2, a second, rear oil collecting space 18 is formed, on the latter lowest point also an oil snorkel 20 is arranged, which is a second Oil suction line 22 with a suction side of a second pump stage of the lubricating oil pump 10 is connected.

In die Ölwanne 2 ist ein Kunststoff - Einlegeteil 24 eingesetzt, das die beiden Ölsammelräume 12 und 18 voneinander trennt. Das Einlegeteil 24 dient als Ölbarriere und verhindert auch bei Steigungsfahrten des Kraftfahrzeugs, dass das Schmieröl aus dem ersten Ölsammelraum 12 in den Kurbelraum und/oder in den zweiten Ölsammelraum 18 übertreten kann. Im zweiten Ölsammelraum 18 wird das Schmieröl von den Hauptlagern der Kurbelwelle und das Schmieröl aus den nicht dargestellten Spritzdüsen für die Kolbenkühlung aufgefangen und über die zweite Ölabsaugleitung 22 in den ersten Ölsammelraum 12 zurückgefördert.In the oil pan 2, a plastic insert 24 is inserted, the two Separates oil collection spaces 12 and 18. The insert 24 serves as an oil barrier and also prevents the lubricating oil from running out when driving uphill the first oil collection chamber 12 in the crank chamber and / or in the second Oil collection chamber 18 can cross. The lubricating oil is in the second oil collecting space 18 from the main bearings of the crankshaft and the lubricating oil from the ones not shown Spray nozzles for the piston cooling collected and via the second oil suction line 22 in promoted the first oil collection chamber 12.
