  • An oil snorkel 6 is placed at its deepest point in the first oil collecting space 4, which leads via a first oil suction line 8 to the suction side of an oil pump 10.
  • a second installation space 12 Arranged in the oil collecting housing 2 is a second installation space 12, which is referred to below as the second oil collection space and which is flatter than the first oil collection space 4.
  • An oil snorkel 14 is also arranged at its lowest point in the second oil collection chamber 12, which is connected via a second oil suction line 16 to a second suction side of the oil pump 10 designed as a double pump
  • a plastic insert 18 is inserted into the oil collecting housing 2, the structure of which is described in more detail below.
  • the insert part 18 has a middle part 20 which, as shown in particular in FIGS. 2 and 3, separates the two oil collecting spaces 4, 12 from one another in the installed state.
  • the middle part 20 has a first side wall 22 oriented towards the first oil collecting space 4, which is provided with a curved wall section 23 forming a bulkhead for the lubricating oil.
  • This tongue and groove connection is additionally sealed by silicone or soft foam, since it is intended to prevent lubricating oil from the first oil collecting space when the motor vehicle is at an incline 4 arrives in the second oil collecting space 12.
  • the first side wall 22 of the insert part 18 is designed such that the lubricating oil can flow from the first oil collecting space 4 under the central part 20, in particular when the engine is at an angle. This section of space is thus also used to hold the oil volume required for a reliable supply of lubricating oil.
  • a top wall 26 of the central part 20 is lowered towards the center (see section line IV - IV in FIG. 3) of the oil collecting housing 2 and consists of two lowered partial surfaces 26a and 26b which merge into a straight partial surface 26c in the middle.
  • the side edge 28 of the top wall 26, which is oriented towards the first oil collecting space 4, hereinafter referred to as the oil holding edge, serves as an oil barrier which prevents the lubricating oil from passing from the first oil collecting space 4 into the second oil collecting space 12 when the vehicle is traveling uphill.
  • the second oil suction line 16 leading to the second oil collecting space 12 runs above the centrally aligned straight partial surface 26c.
  • Two side parts 30 and 32 are integrally formed on the central part 20, in which part of the oil return channels leading from the cylinder head to the first oil collecting space 4 are integrated.
  • the two side parts 30 and 32 have oil return openings 34, which are surrounded by sealing rings 36. That in the embodiment with five
  • Oil return openings 34 provided side part 32 extends over the entire length of the oil collecting housing 2, while the side part 30 provided with four oil return openings 34 in the exemplary embodiment extends from the second oil collection space 12 to the beginning of the first oil collection space 4.
  • the oil return openings 34 arranged in the two side parts 30 and 32 each open into an oil collection channel 38 and 40, which are each provided with an oil drain opening 42 and 44 at their lower ends. Except for the oil return openings 34 to the crankcase (not shown), the two oil collection channels 38 and 40 are closed off by cover elements 46, which are fastened to the side parts 30, 32, for example by vibration welding.
  • the holes made on the flange surface of the crankcase lower part corresponding to the oil return openings 34 sit sealingly with their bore edges on the sealing rings 36.
  • the oil return channels integrated in the crankcase 5 and the oil collection channels 38 and 40 reaching up to below the oil level of the lubricating oil located in the first oil collecting space 4 ensure that the lubricating oil is quickly fed into the first oil collecting space 4 by the consumers despite the pressure pulsations caused by the crankshaft and piston movements got back.
  • the lubricating oil from the main bearings of the crankshaft and the lubricating oil from the spray nozzles (not shown) for piston cooling are collected and pumped back into the first oil collecting chamber 14 via the second oil suction line 16.
