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.
  • Oil pan cover attached oil bulkhead provided in which the oil sump for the Lubricating oil supply to the engine is designed. That from consumers to the Oil pan returned lubricating oil is first outside of the oil extraction space forming oil bulkhead returned before flipping it over in the oil bulkhead monitored openings in the actual oil extraction chamber.
  • the structure of the Oil bulkhead is relatively complex; also v. a. at lateral accelerations of the Vehicle oil movements within the oil pan possible, which pose a risk that there is not enough lubricating oil in the oil extraction chamber
  • Such oil pans are known from JP58200017.
  • the invention is therefore based on the object, the oil movements within a Reduce the oil guide housing or an oil pan; the constructive Implementation can be easily integrated into the oil guide housing.
  • the oil movements are separated by the oil bulkhead separating the oil suction chamber effectively reduced within the oil guide housing; the oil transfer from the Edge areas surrounding the oil extraction chamber is only defined via the in the Openings provided for oil bulkheads possible.
  • they are used for defoaming the oil in the oil collecting spaces provided oil / air separator together with the oil bulkhead as pre-assembled Unit inserted in the oil guide housing or in the oil pan.
  • the oil bulkhead walls separating the oil extraction chamber from the oil collection chamber become supported at the bottom by a cover, which simultaneously holds the oil pan or the Seals the oil guide housing downwards.
  • the proposal according to the invention is in particular for a boxer engine with lying Suitable cylinders, in which the lubricating oil extracted from the cylinder heads in each an oil collection chamber adjoining the oil extraction chamber is introduced before it over the openings monitored by flaps, which are inserted in two in the oil pan Oil bulkheads are provided, which passes into the actual oil suction chamber.
  • 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 is there from an oil suction chamber 16, in which a main oil pump, not shown leading oil suction snorkel 17 is arranged.
  • the two oil bulkheads 22 and 24 are inserted in the oil pan.
  • this guide ribs formed integrally from the two crankcase halves 2 and 4 40 and 42 are provided, into which the two oil bulkheads 22 and 24 are inserted.
  • Corresponding to the guide ribs 40 and 42 provided on the crankcase are the two oil bulkhead walls 22 and 24 in the engagement area with a comb-like Provided guide structure 44 which is held between the guide ribs 40 and 42.
  • a rubber seal 46 is provided for additional sealing of the two oil collection spaces 18 and 20 against the Oil extraction chamber 16 is between the guide rib 40 and the rear of the comb-like Guide structure 44 .
  • Both oil bulkheads 22 and 24 are each with two window-like openings 48 and 50 provided by two each acting as check valves Flow flaps 52 and 54 are monitored.
  • Flow flaps 52 and 54 are monitored.
  • For attachment which only in the Oil extraction chamber 16 opening flow flaps 52 and 54 are for each Flow flap 52, 54 two each attached to the oil bulkheads 22 and 24 Holding pins 56 are provided, on which the flow flap 52, 54 is mounted; the flow flaps 52, 54 are preferably made of rubber.
  • Between the Oil pan cover 14 and the two oil bulkheads 22 and 24 through the Oil pan cover 14 are supported downwards to seal the two Oil collecting spaces 18, 20 with respect to the oil extraction space 16, a rubber seal 58 intended.
  • 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 38 (oil return shown by the arrows), via the oil lines 30, 32 and via the two swirlpots 26, 28 into the two oil collection spaces 18 and 20 promoted back.
  • the two Swirlpot 26 and 28 the oil in a known manner and Defoamed way, d. H. a large part of the gas components is passed through the crankcase dissipated outside.
  • the oil returned to the two oil collection spaces 18 and 20 can into the actual oil suction chamber 16 via the flow flaps 52 and 54 transgressed. From there, it is in a known manner via the not shown Main oil pump, the oil suction line 17 engages in the oil suction chamber 16, the Fed back to consumers.
  • the two oil bulkhead walls 22 and 24 and those in the two oil lines 30 and 32 provided swirlpots 26 and 28 are integrally formed and are as pre-assembled unit inserted in the oil pan and attached to it.
