Definitions

  • the invention relates to dry sump lubrication for an internal combustion engine the preamble of claim 1.
  • This dry sump lubricating oil system includes oil sumps that are on an underside of a crankcase of the internal combustion engine are arranged.
  • US-A-5887564 discloses dry sump lubrication with an oil reservoir on the Front wall (Fig 10) of the internal combustion engine.
  • This container has a rectangular shape and extends in the amount of about 30% of the internal combustion engine.
  • the object of the invention is a dry sump lubrication for a To create internal combustion engine, the oil tank functional and spatial is conveniently arranged on the internal combustion engine.
  • the main advantages achieved with the invention are that the Oil container due to its space-saving shape to a simple construction of a Dry sump lubrication helps, which is easy with an internal combustion engine can be realized. That the oil tank on the internal combustion engine by means of elastic Bearing elements is held in position, ensures a decoupled i.e. low-noise Low-vibration interaction of the oil tank with the internal combustion engine.
  • the return line made of metal ensures on the one hand that it is the suction pressure of a Oil pump withstands.
  • the bellows serves to close the oil tank decouple and compensate for tolerances between him and the internal combustion engine.
  • the check valve ensures that when the engine is at rest the lubricating oil introduced into the oil container remains there and does not open undesirably flows into the internal combustion engine. Because of the opposite the internal combustion engine would have a relatively high level of lubricating oil in the oil tank the check valve lower lying cylinders and combustion chambers e.g. one Boxer internal combustion engine flooded and low-emission operation of the Internal combustion engine difficult.
  • the check valve and its pipe socket-like Housings are components that are easy to manufacture with reasonable effort can be installed between the return line and the internal combustion engine.
  • FIG.1 1 shows a view of an end face of an internal combustion engine with an oil container of a dry sump lubrication according to the invention
  • Fig. 2 2 shows a view in the direction of the arrow X in FIG. 1
  • Fig. 3 Components of Fig.1 at Y on a larger scale.
  • An internal combustion engine 1 with opposite and horizontally aligned Cylinder rows - boxer type - is provided with dry sump lubrication 2. at the dry sump lubrication 2, the lubricating oil is not in the crankcase or Sump of the internal combustion engine 1 is stored, but in an oil container 3.
  • the Oil reservoir 3 is connected via an inlet line 4 and a return line 5 an oil circuit of the internal combustion engine 1, not shown.
  • the internal combustion engine 1 In order to save space on the internal combustion engine 1 around the oil container 3 affiliate, it has a flat, rectangular cross-section. And he's upright arranged standing on an end face 6 of the internal combustion engine 1.
  • the Oil container 3 relatively close to the internal combustion engine 1, and it runs with short sides 7,8 in the longitudinal direction A-A and with long sides 9,10 in the transverse direction B-B the said internal combustion engine.
  • the oil tank 3 extends over a substantial part of the total height Gh of the internal combustion engine 1, the Oil tank 3 above one, on a lying cylinder - boxer / type - attached cylinder head 12 with a section that projects in sections 13 is provided, whereby the volume of the oil container 13 can be optimized.
  • the internal combustion engine 1 are a plurality of elastic bearing elements 14, 15, 16 provided by which the oil container 3 decouples on the internal combustion engine or on one of their housings is held in place.
  • the return line 5 is formed by a pipe socket 19 led away from the oil container 3 and the Bellows 18; the latter are made separately.
  • the return line 5 is a check valve 20 downstream, which between the return line 5 and a connection 21 of the internal combustion engine 1 is arranged.
  • Check valve 20 ensures that the oil level 22 in the oil reservoir 3 is at a standstill of the internal combustion engine the predetermined level remains and no oil penetrates the internal combustion engine 1.
  • the check valve 20 is surrounded by a pipe socket-like housing 23 and comprises an axially movable valve body 24 which is connected to a valve seat ring 25 of the Bellows 18 as a function of the operating state of the internal combustion engine 1 cooperates.
