Definitions

  • the invention relates to an oil collecting device for an internal combustion engine, in particular for a boxer engine according to the preamble of patent claim 1.
  • the object of the invention is to improve the so-called.
  • Integrated dry sump To further improve functionality in order to achieve a high degree of integration at the same time includes a reduction in the scope of pre-assembly.
  • one is formed in the oil collecting space from a wall section Inclined provided that as a drainage surface for the returned to the oil collection space Lubricating oil is used.
  • This sloping side wall of the oil collection space supports the oil return from the cylinder heads to the extraction point in an advantageous manner.
  • the lubricating oil returned from the cylinder heads hits the oblique one running drainage surface and from there passes over the in the oil bulkhead provided openings in the oil extraction chamber.
  • running drainage surfaces can maintain the volume of the oil collecting space the functionality of the pressure lubrication can be reduced.
  • they serve Drain surfaces through the defined flow of the returning oil to Defoaming of the lubricating oil; they take over the function of otherwise Usually used oil / air separators, the so-called swirlpots.
  • the wall section provided with the lubricating oil drainage surface in the oil collecting space is open advantageous way in one piece from the oil collection housing down final oil cap formed. This can be for the drain surface provided plastic part are molded so that the previous one in the oil sump Dead spaces can be significantly reduced. So that the internal combustion mesh with a lower amount of lubricant in circulation, which means weight and Cost advantages can be claimed.
  • the sloping drainage surfaces which simultaneously defoam the lubricating oil are provided, can also be provided with ribs, knobs or similar shaped bodies be provided so that the lubricating oil on the way into the oil extraction chamber is degassed accordingly.
  • the two oil bulkheads delimiting the oil extraction space and in the oil collection space arranged oil return lines are in one piece as a kind of pre-assembly module summarized.
  • the integration of the components belonging to the dry sump is further increases when the oil suction snorkel located in the oil collection chamber with the two Oil return lines is combined in one piece as a common module.
  • the crankcase of a 6-cylinder boxer engine shown in section in FIG. 2 consists of two crankcase halves 2 without limitation to this embodiment and 4 with two horizontally arranged rows of cylinder banks 1 to 3 and 4 to 6 (not ) Shown. From each of the two crankcase halves 2 and 4 is one down extending wall sections 6 and 8 formed, which together with one at the Flange surfaces 10 and 12 of the two wall sections 6 and 8 fastened oil covers 14 form an oil collecting housing, hereinafter referred to as an oil pan.
  • the oil pan faces an oil suction chamber 16, in which a main oil pump, not shown leading oil suction snorkel 18 is arranged.
  • two oil collection spaces 20 and 22 are formed, which are opposite the oil extraction space 16 are separated by two oil bulkheads 24 and 26. Both oil bulkheads 24 and 26 are provided with three window-like openings 28, 29 and 30, respectively by means of a flow flap 32 and 34 acting as a check valve are monitored.
  • Flow flaps 32 and 34 are four for each flow flap 32, 34 Oil bulkheads 24, 26 provided holding pins 36 on which the Flow flap 32, 34 is mounted; preferably there are elastic ones Flow flaps 32, 34 made of rubber.
  • the oil suction snorkel 18 is at the same time on the connection plate 52 connected in one piece, the connecting flange 58 of the oil suction snorkel 18 on Crankcase 2 is screwed.
  • the two form Oil bulkheads 24, 26 and the two oil return lines 42, 44 together with the Oil suction snorkel 18 a one-piece plastic bulkhead module, which as prefabricated assembly unit is formed.
  • the oil cover 14 which is also made of plastic, has the side limitation of the two oil collection spaces 20 and 22 two integrally connected to the oil cover 14 Ramps 60 and 62 on in the assembled state of the engine in the two Intervene in oil collecting spaces 20 and 22.
  • the two ramps 60 and 62 each have one which delimits the oil collecting space 20 or 22 and is provided with a slope Wall section 64 and 66, which acts as an oil drainage surface for the oil collecting space 20, 22 returned lubricating oil, as will be explained in more detail later, serves.
  • two cylindrical sealing stubs 68 and 70 are also formed, which are in the assembled state in openings 72 and 74 provided in crankcase 2, 4 intervene sealingly.
  • a drain plug for the coolant can be provided.
  • the one made of plastic Existing oil cover 14 has a for sealing against the flange surfaces 10, 12 circumferential groove-shaped contour 76, in which an elastomer seal 77 is inserted.
  • 4 are still on the Outer contour of the oil cover 14 corresponding flange screwing points 78 developed. It engages in a cup-shaped recess 80 provided in the oil cap 14 the oil suction snorkel 18.
  • the oil is returned to the oil pan in the following way:
  • the lubricating oil extracted from the two cylinder heads of the engine is transferred to the two oil return channels 50 (oil return shown by the arrows in Fig. 1) and over the two oil return lines 42 and 44 into the two oil collection spaces 20 and 22 conveyed back.
  • the lubricating oil drains off on the wall sections 64, 66 the lubricating oil defoams and thus the gaseous components of the lubricating oil be separated.
  • the defoaming of the back-flowing lubricating oil can continue be improved if the drainage surfaces 64, 66 additionally with ribs, knobs o. ⁇ . Shaped bodies are provided.
  • FIG. 5 shows a second embodiment, which is compared to the first Embodiment only slightly modified and identical in functionality to first embodiment is formed.
  • the oil suction snorkel 18 is not attached in one piece to the bulkhead module, but instead running separately, arranged.
