  • the forces resulting from the combustion can be thus derive specifically.
  • Known internal combustion engine results in an internal combustion engine with the Crankcase according to the invention despite the same range of services much lower Has external dimensions.
  • an internal combustion engine with the crankcase according to the invention has so little based on the same performance
  • Cross-sectional dimensions that a crankcase according to the prior art, with comparable cross-sectional dimension, very poor bending and torsional rigidity would.
  • the section modulus increases with the 4th power of the height or Width of the box dimensions.
  • the in the chambers Auxiliary units, heat exchangers, filter and oil storage rooms are arranged.
  • the auxiliary units in particular the Oil pumps and the oil reservoirs into the chambers on one side of the crankcase are arranged.
  • the heat exchangers and filters are on the other side arranged.
  • a chamber be self-contained closed oil reservoir.
  • several chambers can be one Be connected to each other so that they form a common oil reservoir.
  • the chambers opposite the Atmosphere are closed by a cover.
  • the entire oil routing system is thus - without separate housing or container - fully integrated into the crankcase.
  • the Transition of the chamber serving as an oil reservoir to the crankshaft chamber is as Single wall executed.
  • the connection Crankcase / oil reservoir is thus designed as a double wall, the Cable bushings must be processed and sealed accordingly.
  • crankcase in the region of the crankshaft space by means of a supporting floor cover is closed.
  • a cross bar is provided for each end wall.
  • crankcase 1 is shown in a view of the force side.
  • the crankcase 1 is made of cast aluminum. This is cuboid with rectangular cross-section, the base of the cuboid approximately corresponds to the lateral throat in the area of the cylinder heads (maximum engine width).
  • the base side 15 corresponds to the section AA in FIG.
  • the crankcase 1 has at least one chamber 2.
  • the crankcase 1 shown in FIG. 1 has three chambers 2. There is preferably one chamber 2 on each side for each two-cylinder disc intended. For an internal combustion engine with six cylinders, these are three chambers 2 per side.
  • the chamber 2 on the force side is formed from: first Front wall 17, transverse wall 3, part of the base 9 and one Wall 19 delimiting crankshaft space 10. This wall cannot be seen in FIG. 1, since it is inside the crankcase 1.
  • the chambers 2 are the Auxiliary units, heat exchangers, filters and oil storage rooms arranged.
  • the auxiliary units in particular the oil pumps and the oil storage rooms in the Chambers 2 arranged on one side of the crankcase 1.
  • the heat exchangers and However, filters are in the chambers 2 on the other side of the crankcase 1 arranged. In addition to a clear structure, this results in the advantage of short ones Connecting lines.
  • the chambers 2 are exposed to the atmosphere by means of a Cover 20 closed.
  • the cover 20 extends in the assembled state the entire side surface of the crankcase 1. This is shown in Figure 4.
  • a chamber 2 can represent a self-contained oil reservoir. Alternatively, several chambers 2 on one side can also be connected to one another form an oil reservoir overall. This enables the complete oil system the internal combustion engine - without separate housing or container - fully into the crankcase to integrate.
  • first end wall 17 has a first cross bar 4.
  • the cross bar 4 serves to stiffen the crankcase 1.
  • the advantages of the invention built housing "with cross bolts are the avoidance of so-called 3-country corners on the lower and front seals. They enable sealing surfaces in one plane with O-ring grooves in the covers.
  • Reference number 7 shows a flange ring on the force side of the crankcase 1, which together with the cross bar 4 forms a flange surface.
  • crankcase 1 is shown with a view of the opposite side of the force.
  • Reference numeral 18 shows a second end wall. Points in the area of the base 9 the second end wall 18 has a second cross bar 5.
  • the function is corresponding the first crossbar 4 from Figure 1.
  • the crossbar 5 forms together with the circumferential end face 24 of the crankcase the flange face for a gear case cover. This applies to the arrangement and function of the chambers 2 in FIG. 1 said.
  • a bearing bracket 6 is shown in Figure 2.
  • This bearing bridge 6, several bearing bridges are arranged within the crankcase 1, serve known as a bearing bracket for the crankshaft. To accommodate the of the Forces exerted on the crankshaft, the bearing bracket 6 is screwed twice. To do this refer to Figure 4.
  • the base side 15 of the crankcase 1 corresponds approximately the lateral projection in the area of the cylinder heads.
  • the basic page 15 corresponds to the route AA.
  • Figure 3 shows the crankcase 1 with a view of the base 9.
  • the chambers 2 and the two crossbars 4 and 5 applies said in Figures 1 and 2.
  • the two crossbars 4 and 5 are after milling the Camp alley and the crossbar contact surface wetted with sealant and inseparably with the Screwed crankcase 1 and pinned.
  • the crankshaft space 10 is opposite the Atmosphere closed by means of the bottom cover 12. This contributes to the supporting structure at and can be seen from Figure 4.
  • Figure 4 shows a cross section through the crankcase 1.
  • the left half is designed as a section through a transverse wall 3.
  • the right half is designed as a section through a chamber 2.
  • Numeral 2 shows a chamber. This is formed from part of the base area 9, a wall 19 delimiting the crankshaft space 10 and a cover 20 which seals the chamber 2 from the atmosphere.
  • the chamber 2 can represent a self-contained oil reservoir.
  • a plurality of chambers 2 on one side can also be connected to one another and form a common oil reservoir.
  • Such an opening to a further chamber 2 is represented by reference numeral 21.
  • the oil pumps are located inside the oil reservoir, chambers 2.
  • the cover 20 is load-bearing and part of the rigidity concept.
  • Reference numeral 23 shows a charge air manifold, which is at least partially an integral part of the crankcase 1.
  • the transverse wall is shown with reference number 3. This is made in one piece with the crankcase 1.
  • the transverse wall 3 serves to increase the rigidity of the crankcase 1 and to form the chambers 2.
  • the cover 20 has been omitted.
  • a bearing bracket is shown at 6. This is fastened to the crankcase 1 both from the direction of the base surface 9 and from the direction of the side surface by means of screws 11. This transverse screw connection, that is to say from the side surface, is pulled out to the outer edge B of the transverse wall 3.
  • crankcase 1 In the area of the crankshaft chamber 10, the crankcase 1 is closed by means of a bottom cover 12. The bottom cover 12 contributes to the rigidity of the crankcase 1. An additional oil storage space 13 is arranged on this floor cover 12. As can be seen in Figure 4, the crankcase 1 is cuboid with a rectangular cross section. The base side 15 of the crankcase 1 approximately corresponds to the lateral projection (maximum engine width) in the area of the cylinder heads 16, that is to say the distance AA.
