Definitions

  • the invention relates to an internal combustion engine with a crankcase, in which a crankshaft is rotatably mounted, according to the closer defined in the preamble of claim 1 Art.
  • a generic internal combustion engine is from the DE 44 24 248 C1 known.
  • the oil is pumped through extending within walls of the cylinder head pressure channels and adjoining longitudinal channels to within the crankcase arranged air-oil separation elements to separate the air from the oil flowing back into the oil pan.
  • the disadvantage here is the high casting complexity for creating the relatively long channels, the large footprint and the high drive power, which is needed for pumping the oil and for separating the air from the oil.
  • the DE 40 01 468 A1 describes an oil guide housing for an internal combustion engine in which trained as ribs oil planer are provided, with which the oil is planed from the connecting rod and returned via return ducts in the oil pan. By said construction, however, no separation of air from the oil pan recycled oil is possible.
  • the inventive one-piece design of the at least one air-oil separator with the ⁇ labstreif sexualen results in a very compact design these two parts, so that they can be integrated into the internal combustion engine without major problems. Due to the small distance of the air-oil separator from the ⁇ labstreif sexualen can also be dispensed with a pump, as is dominated by the prevailing in the air-oil separator high kinetic energy, the oil is stripped off and due to the density difference between air and oil an independent Oil separation takes place or is achieved. Another advantage of the solution according to the invention is that in the crankcase no additional channels or the like must be integrated, so that there is no additional casting technical effort.
  • At least one oil outlet opening of the air-oil separation device is located above the oil level of the oil pan in each driving state of the motor vehicle equipped with the internal combustion engine according to the invention, so that it is always ensured that the oil is returned freely and without resistance to the oil pan.
  • all oil outlet openings are arranged above the oil level adjusting in the oil sump.
  • the longitudinal axis of the air-oil separator around which the oil introduced rotates substantially parallel to the crankshaft, so additional space problems are prevented, since the air-oil separator in the direction of its longitudinal axis usually very is much larger than in a plane perpendicular to it. That is, the air-oil separator is installed horizontally, but the function of the same does not affect, since the oil is not due to gravity, but due to the high centrifugal force in the same passes.
  • each oil wiper device is associated with a connecting rod, and that each oil wiping device has two oil wiping openings arranged one behind the other in the direction of rotation of the crankshaft.
  • each ⁇ labstreifö réelle a narrowing Channel leads to the air-oil separator.
  • the flow rate of the oil is increased and it can be fed even faster to the air-oil separator in this way.
  • Fig. 1 shows an internal combustion engine 1 with a crankcase 2, attached to the crankcase 2 cylinder heads 3 and the cylinder heads 3 in a conventional manner final cylinder head cover 4.
  • the internal combustion engine 1 is designed in the present case in boxer design, but it could also in any other design be executed.
  • the crankcase 2 has in this case two crankcase halves 2a and 2b, between which a crankshaft 5 is mounted with a plurality of attached connecting rods 6 and performs in a conventional manner a rotational movement.
  • only one of the connecting rods 6 is shown, but the number of them coincides with the number of cylinders (not shown) of the internal combustion engine 1 and can thus vary almost as desired.
  • Below the crankcase 2 is an oil pan 7, in which the oil used for lubrication of the internal combustion engine 1 is added.
  • the internal combustion engine 1 thus has a wet sump lubrication.
  • the internal combustion engine 1 further comprises a plurality of oil scrapers 8, which are used for stripping oil from the rotating crankshaft 5 and the attached thereto and with the same rotating connecting rods 6 and thus to prevent free spraying or with the crankshaft 5 and the connecting rods 6 in the form of an oil roller with rotating oil.
  • each ⁇ labstreif issued 8 is assigned to a connecting rod 6, since a considerable amount of oil is carried by the connecting rods 6.
  • a connecting rod 6 in an internal combustion engine 1 with only one cylinder and consequently a connecting rod 6 so only one ⁇ labstreif sexual 8 would be provided.
  • Optionally could be dispensed with individual connecting rods 6 and the attachment of a ⁇ labstreif sexual 8.
  • the ⁇ labstreif sexualen 8 are integrally formed with a plurality of known as Swirlpot air-oil separation devices 9, in which the introduced from the crankshaft 5 and the connecting rods 6 stripped or planed oil is introduced and defoamed.
  • the oil scrapers 8 and the air-oil separators 9 are shown in more detail in FIG.
  • the ⁇ labstreif sexualen 8 additional cover elements 10 are assigned, which are preferably formed of sheet metal and prevent backflow of oil from the oil pan 7 in the crankcase 2.
  • the cover 10 also serve to attach the ⁇ labstreif recognizeden 8 to the crankcase 2. It can be provided between the cones 6 associated ⁇ labstreif sexualen 8, the crank webs of the crankshaft 5 associated ⁇ labstreif recognizeden to achieve even better stripping of oil.
  • each ⁇ labstreif issued 8 two ⁇ labstreifö réelleen 11 which are arranged in the rotational direction of the crankshaft 5 one behind the other and adapted to the designated with a line 6a envelope of the connecting rod 6 during its movement.
  • each ⁇ labstreifö réelleen 11 each leading a narrowing channel 12 to the assigned in the present embodiment each ⁇ labstreif responded 8 air-oil separator 9 and enters at a respective oil inlet opening 13 in the respective air-oil separator 9 a.
  • the air-oil separation devices 9 have in the present case a substantially cylindrical housing 14 and its longitudinal axis 15 extends substantially parallel to the crankshaft. 5
  • the air-oil separation device 9 has a substantially central, so arranged on the longitudinal axis 15 of the same 16 Luftabloomtechnisch through which the separated air from the oil can leave the housing 14.
  • the air discharge line 16 may extend more or less deeply into the housing 14 of the air-oil separator 9. The entering into the housing 14 of the air-oil separator 9 oil moves due to the centrifugal force on the inner wall of the housing 14 along a helical path in the direction of the air discharge line 16 opposite oil outlet 17, which is shown in Fig. 7 schematically.
  • the movement of the oil in the direction of the oil outlet opening 17 can be assisted by a design of the channels 12 inclined in the direction of the same. Due to the lower density of the air, this leaves the circulating oil flow inwards and can therefore escape through the air discharge line 16. The oil, however, can leave any air-oil separator 9 at the oil outlet 17.
  • the oil outlet opening 17, as can be seen in FIG. 7, is arranged so that it is located above an oil level 18 indicated in FIG. 7 in the oil pan 7 in each driving state of a motor vehicle equipped with the internal combustion engine 1.
  • a further line could also be led to a common oil outlet opening, which then likewise in each driving state of the equipped with the internal combustion engine 1 motor vehicle should be above the oil level 18 in the oil pan 7.
  • the oil level 18 shown in FIG. 7 results in the oil pan 17.
  • FIG. 7 further shows a suction opening 19, which is spaced from the bottom of the oil pan 7 by at least one spacer 20.
  • an oil pump not shown, sucks the lubricating oil from the oil pan 7 and forwards it to the lubrication points inside the internal combustion engine 1.
  • the suction opening 19 should be in each driving state of the motor vehicle or at each vehicle position below the thereby adjusting oil level 18.
  • Figures 5 and 6 show an alternative embodiment of the air-oil separation devices 9.
  • a plurality of ⁇ labstreifvoriquesen 8 is associated with a common air-oil separator 9, which also has a cylindrical housing 14 whose longitudinal axis is substantially parallel to the crankshaft 5 ,
  • two air-oil separation devices 9 are provided, each associated with three connecting rods 6. Due to the higher volume of oil to be expected, the volume of the air-oil separators 9 is greater than that of the embodiment illustrated in FIGS. 3 and 4, with respect to which the embodiment of FIGS. 5 and 6 enables simpler manufacture. In contrast, the embodiment of Figs. 3 and 4 is more effective due to the smaller volumes of the air-oil separators 9.
