Definitions

  • the invention relates to an internal combustion engine of the genus Main claim.
  • Such an internal combustion engine is, for example, in DE 32 03 312 C2 described.
  • the lubricating oil supply of this internal combustion engine takes place via a Oil pump, which is designed as an internal gear pump and in an end cover the crankcase is inserted.
  • the oil pump is on a shaft journal Crankshaft fitted and driven by this.
  • So driven and arranged internal gear pumps lead to an increase in the axial length the internal combustion engine. It also requires the training of Pump housing in housing parts of the internal combustion engine a considerable Manufacturing effort. Flange a separate pump housing to the Front of the internal combustion engine would further increase the overall length to lead.
  • such internal gear pumps are of defined sizes not always able to have a sufficient volume of lubricant available put.
  • depending on the shape of the oil pan is a relative great suction height given by the arrangement on the crankshaft.
  • the invention is based on the object of an internal combustion engine according to the genus of the main claim so that the lubricating oil supply is possible with high delivery volumes, the oil pump on simple and space-saving way to be housed on or in the internal combustion engine.
  • the arrangement of the oil pump should be the external dimensions of the Do not significantly change the internal combustion engine.
  • one should be as possible low suction head of the pump and thus security against cavitation and a possible high efficiency can be guaranteed.
  • a particularly space-saving, easy-to-install accommodation at very Low suction head is given when the oil pump on the underside of the Crankshaft bearing frame is attached.
  • the oil pump can thus be within the Install the space enclosed by the oil pan so that no additional Sealing effort on the housing of the internal combustion engine must be operated and an increase in length, apart from the pure pump drive, avoided becomes.
  • By placing the oil pump in the area of the front of the Internal combustion engine is a simple drive of the oil pump via an end Stub shaft of the crankshaft possible. Also on the sealing of the oil pump itself can due to the housing within the closed off from the oil pan Lower demands are made of space.
  • the drive of the oil pump can be done with a simple arrangement Belt drive, in particular a chain drive, take place so that the Manufacturing tolerances with regard to the pump drive are low are.
  • the drive via a gear transmission would also be possible without any problems.
  • this partitioning can Take up oil channels that connect the oil pump to one or manufactures several risers. By placing horizontal oil channels in it Foreclosure arises without significant additional manufacturing expenditure Double use of the known partitioning of the crankshaft space.
  • the internal combustion engine shown as an embodiment in FIGS. 1 to 3 is as four-cylinder in-line engine with a crankcase 1 in open-deck design educated.
  • the crankcase 1 has four cylinder liners 2 in which pistons 3 are guided, the connecting rods 4 are connected to a crankshaft 5.
  • the crankshaft 5 is mounted in the crankcase 1, the upper bearing halves 6 in the crankcase are trained.
  • the lower bearing halves 7 are formed in bearing bridges 8 which are combined into a ladder-like crankshaft bearing frame 9.
  • the Crankshaft bearing frame 9 is made of light metal and has in the range lower bearing halves 7 ferrous metal inserts 10.
  • the crankshaft 5 receiving space 11 is through a cover 12 with oil scoops down sealed off.
  • the cover is integral with the crankshaft bearing frame 9 connected.
  • the crankcase 1 is on its underside by a flanged oil pan 13 locked. When the internal combustion engine is operating, it forms in the oil pan below the cover 12 of the crankshaft bearing frame 9 from an oil sump, which for Lubricant supply to the internal combustion engine is used.
  • To the bottom of the Cover 12 or the crankshaft bearing frame 9 is a gear pump 14 flanged, the two gears 15, 16 meshing with each other in external engagement having.
  • the drive shaft 17 of the gear pump 14 is in the area of the front End wall 18 of the oil pan 13 provided with a sprocket 19, which has a Drive chain 20 with one on the front stub shaft 21 of the crankshaft 5 attached chain wheel 22 is driven. Both sprockets 19, 22 and Drive chain 20 are located within the crankcase 1 and the oil pan 13 enclosed space.
  • the suction line 23 of the gear pump 14 is provided with a suction basket 24 which in the lower region of the oil pan 13 below that which arises during operation Oil level is arranged.
  • the opposite end of the Connecting tube 25 is inserted into an opening 27 in the oil pan 13, which with a heat exchanger 28 is connected, which is attached to the outside of the oil pan is.
  • the pumped oil of the gear pump 14 flows through the heat exchanger 28 and a downstream oil filter 29, from where it flows through the Heat exchanger 28 is conveyed into an oil nozzle 30 projecting into the oil pan 13.
  • This oil nozzle 30 is connected to a pipe connection 31, which is part of a existing horizontal oil gallery 32 is several oil channels.
  • This horizontal Oil gallery 32 is integrally formed on the underside of the cover 12 and includes one over almost the entire length of the internal combustion engine extending longitudinal channel 33 and two side channels 34, 35.
  • the longitudinal channel 33 and the side channels 34 and 35 are closed at the ends and with vertical extending riser 36, not shown, via which the individual areas to be lubricated, e.g. Crankshaft bearings, Camshaft bearings, rocker arm bearings, camshaft adjustment, Spray oil cooling and the like are supplied with lubricant.
