Definitions

  • the invention relates to a cylinder crankcase for an internal combustion engine according to the preamble of claim 1.
  • PCT application WO 2004/009986 A1 discloses a cylinder crankcase produced by die casting for an internal combustion engine, in which a bushing composite is cast, which consists of a plurality of cylinder liners arranged in a row and interconnected by webs. For cooling, interconnected cooling channels are introduced into the cylinder liners and into the webs, forming a water jacket.
  • a bushing composite for cooling, interconnected cooling channels are introduced into the cylinder liners and into the webs, forming a water jacket.
  • the present invention seeks to avoid the disadvantages of the prior art, and to provide a low-priced cylinder crankcase with a thermally and mechanically highly resilient liner composite for pouring into the cylinder crankcase in the die-casting.
  • FIG. 1 is a partially cut cylinder crankcase with a plurality of cylinder liners arranged in the bushing composite
  • Fig. 2 is an enlarged view of an embodiment of a consisting of two blind holes coolant flow and
  • Fig. 3 shows a further embodiment of a consisting of a through bore coolant flow, which is guided through the web and through the located on both sides of the web Umgussmantel.
  • a cylinder crankcase 1 is shown, which is partially cut in the selected representation, wherein the cut surfaces are hatched.
  • the cylinder crankcase 1 consists of a hypoeutectic aluminum-silicon alloy and is produced by die casting, wherein in the cylinder crankcase 1 cylinder liners 5, 6, 7 are cast with, which are arranged in a row and connected by webs 2, 3, 4, so that a bushing composite 9 results.
  • partially cutaway view of the cylinder crankcase three cylinder liners 5, 6, 7 can be seen.
  • the cylinder crankcase 1 has oil return channels 17, 18, 19, 20 and further threaded bores 21, 22, 23, 24.
  • a recess 25 is formed for a water jacket, of which the cylinder liners 5, 6, 7 are surrounded for the purpose of cooling.
  • the recess 25 is bounded by a Umgussmantel 26, of which the cylinder liners 5, 6, 7 and arranged therebetween Webs 2, 3, 4 are surrounded, so that in the embodiment of FIG. 1 dry cylinder liners 5, 6, 7 are present.
  • the bushing composite 9 formed by the cylinder liners 5, 6, 7 is produced by low-pressure casting or by gravity casting.
  • a hypereutectic aluminum-silicon alloy is used which, in addition to aluminum, contains 15% to 21% silicon, 1% to 5% magnesium and 2% to 5% copper.
  • the aluminum-silicon alloy may further contain 0.7% to 1.5% iron and 0.3% to 0.7% manganese.
  • the coolant passage 16 is shown enlarged in FIG. 2 and consists, like the other coolant passages 14 and 15, of a first blind hole 27 introduced into the cylinder head side 30 of the web 4 with an opening 31 in the cylinder head side end 30 of the web 4 and out of one from the cylinder sleeve-side boundary surface 28 of the recess 25 from the overblown casing 26 in the web 4 introduced second blind hole 29 with an opening 32 in the encasing 26, wherein the two blind holes 27 and 29 are aligned so that the second blind hole 29 in the lower end the first blind hole 27 opens.
  • the blind bores 27 and 29 have a diameter of 2.5 mm, wherein the width of the webs 2, 3, 4 is 7 mm in each case.
  • the flow of the coolant, water, through the coolant passage 16 takes place (see FIG. 2) in the present embodiment in the direction of the arrows 31 and 32, since in the assembled engine, the cylinder head, not shown in the figures, is mounted on the cylinder crankcase 1 in that the pressure of the cooling water located in the recess 25 is sufficiently great to drive a portion of the cooling water through the blind bores 29 and 27 and thus to cool the upper portion of the web 4, which is one of the thermally most heavily loaded parts of an internal combustion engine.
  • FIG. 3 shows an embodiment of the cylinder crankcase 1, in which the coolant passages 33 formed in the webs 2, 3, 4 have two openings 34, 35, both of which open via the encasing jacket 26 into the recess 25 for the water jacket.
  • the coolant passages 14, 15, 16 and 33 as well as the blind bores 27 and 29 can be produced by erosion.
