Definitions

  • the invention relates to a cylinder crankcase of an internal combustion engine, in particular of a motor vehicle, with a charge air compressor and a charge air compressor support for supporting the charge air compressor on the cylinder crankcase, according to the preamble of claim 1.
  • crankcase Such a crankcase is known from the generic JP 9242549 A. Lubrication and cooling of bearings of an exhaust gas turbocharger via an oil circuit of the internal combustion engine. For this it is known from JP 9236019 A to provide a separate exhaust gas turbocharger support with integrated oil supply and oil return for this cooling.
  • JP 57049024 A discloses a carrier arranged on the cylinder piston housing of an internal combustion engine with a support arm for fastening an exhaust gas turbocharger.
  • the support arm includes a bottom plate which is integrally attachable to the crankcase thereof.
  • the object of the present invention is to further improve a crankcase of the above-mentioned type with regard to installation space and installation effort.
  • the exhaust gas turbocharger support is formed integrally with the crankcase.
  • channels for a cooling water supply of the exhaust gas turbocharger are integrated into the exhaust gas turbocharger, resulting in the corresponding connection to the cooling water circuit automatically with the assembly of the exhaust gas turbocharger at the Abgasturbotader grounds results without additional hose connection are required. This further simplifies the assembly of the exhaust gas turbocharger.
  • the exhaust gas turbocharger support is formed in a central region at the transition from the crankcase to the cylinder housing on the cylinder crankcase.
  • the exhaust gas turbocharger support has a flange section for fastening the exhaust gas turbocharger, which preferably rises perpendicularly with respect to a central axis of the cylinder crankcase from the exhaust gas turbocharger.
  • a cylinder crankcase 10 comprises a plurality of cylinder bores 12, a cylinder housing part 14, a crank chamber 16, in which a crankshaft, not shown, is arranged, a crankcase part 18 and a oil longitudinal passage 20.
  • an exhaust gas turbocharger support 22 In a region of the cylinder housing part 14 adjacent to Crankcase part 18 is integrally formed with the cylinder crankcase 10 an exhaust gas turbocharger support 22.
  • the exhaust gas turbocharger support 22 includes a flange portion 24 having a flange 26 for attaching thereto an exhaust gas turbocharger, not shown, on the cylinder crankcase 10th
  • an oil return opening 30 with an oil return channel 32 is additionally formed in the flange section 24 for fastening the exhaust gas turbocharger to the flange 26.
  • the oil return opening 30 is aligned with a corresponding bore in the exhaust gas turbocharger, so that it is automatically connected to the attachment to the flange 26 with the integrated in the flange portion 24 oil return 30, 32.
  • the oil return passage 32 opens in a manner not shown back into the crank chamber 16, so that flows from the exhaust gas turbocharger recirculated oil to the oil sump in the crankcase part 18.
  • this oil In addition to the function of lubricating bearings of the exhaust gas turbocharger, this oil also has the function to dissipate waste heat due to the compression of air from the exhaust gas turbocharger, which further improves loading of the cylinder 12 with precompressed air.
  • the flange 26 in addition to the oil return port 30 additionally has an oil inlet 34, which is attached to the flange 26 exhaust gas turbocharger with a corresponding bore in this alignment, so that the exhaust gas turbocharger with the attachment to the flange 26 automatically with the in the flange portion 24 integrated oil inlet 34 is connected.
  • the oil feed opening 34 of the flange 26 indicated by a dashed line is connected to a tap hole 36.
  • This tap hole 36 looks in contact with the oil longitudinal channel 20 and is at one closed at the opposite end 38.
  • the tap hole is an integrated into the flange portion 24 oil inlet channel 36 for the exhaust gas turbocharger, so that there is a compound of the exhaust gas turbocharger for oil supply of the cylinder crankcase 10.
  • the exhaust gas turbocharger support 22 is integrally formed with the cylinder crankcase on a side wall thereof.
  • not shown cooling water channels are integrated into the flange portion 24, which are in communication with a not shown cooling water system of the cylinder crankcase 10. This serves for a corresponding cooling of the exhaust gas turbocharger or a removal of heat energy from this, which results from the compression of the air.
