Definitions

  • ABSTRACT An internal combustion engine in which the cylinder head is secured at the crankcase by means of cylinder head bolts and in which rigid spacer elements are provided between the cylinder head and the crankcase within the area of the cylinder head bolts; the radial collar of the liquid-cooled cylinder liner is mounted directly on the separating surface of the crankcase facing the cylinder head while an intermediate pipe is inserted into the through-passage for the cooling water between the cylinder head and crankcase; the intermediate pipe includes a radial collar and one annular seal each is inserted between the separating surface of the cylinder head and the radial collar of the intermediate pipe as also between the separating surface of the crankcase and the radial collar.
  • the present invention relates to an internal combustion engine in which the cylinder head is secured at the crankcase by means of cylinder head bolts and nonyielding, rigid spacer elements arranged between these housing parts within the area of the cylinder head bolts are provided, and in which the radial collar of the liquid-cooled cylinder liners is mounted directly on the separating surface of the crankcase on the side of the cylinder head and an intermediate pipe is inserted into the through-passage for the cooling water between cylinder head and crankcase which is selaed off by means of sealing rings.
  • the present invention is concerned with the task to provide a structurally simple and effective seal of the cooling water passage with respect to the three separating joints between cylinder head, gas seal, spacer element and crankcase.
  • the underlying problems are solved according to the present inention in that the intermediate pipe or tubular member includes a radial collar, and in that one sealing ring each is inserted between the separating surface of the cylinder head and the collar as also between the separating surface of the crankcase and the collar. It is achieved by the present invention that only two seals are required for the three separating joints.
  • the intermediate pipe or tubular member is clamped-in essentially non-displaceably by its collar so that no wear occurs.
  • Commerically available O-rings can be used as sealing elements so that the expenditures for the replacement and renewal of the seal of the cooling water passage are small.
  • Another object of the present invention resides in a liquid-cooled internal combustion engine which reduces the number of seals required for effectively sealing the intemediate pipe inserted into the cooling water passage between cylinder head and crankcase.
  • a further object of the present invention resides in an intenal combustion engine of th type described above which reduces the number of seals necessary in the connection for the cooling liquid between crankcase and cylinder head.
  • a still further object of the present invention resides in an internal combustion engine with intemediate pipes inserted into the through-passages for the cooling water between cylinder head and crankcase which not only utilizes relatively few parts but permits the use of commerically available seals thus reducing the cost in case of replacement of warm seals.
  • Another object of the present invention resides in an internal combustion engine of the type described above which not only assures a uniform compression of the seals but also minimizes stresses in the various parts.
  • the single FIGURE is a partialcross-sectional view through the crankcase and cylinder head of an internal combustion engine in accordance with the present invention.
  • reference numeral 1 designates therein the separating surface of the crankcase 2.
  • the radial collar 3 of the wet cylinder liner 4 is mounted directly on the separating surface 1 of the crankcase 2.
  • the collar 3 is sealed with respect to the separating surface 6 of the cylinder head 7 by means of a metallic gas seal 5 of conventional construction.
  • a distance or spacer plate 8 is inserted between the crankcase 2 and the cylinder head 7; the spacer plate 8 is provided with an aperture 9 for the collar 3 and with a cooling water passage generally designated by reference numeral 10 between thecrankcase 2 and the cylinder head 7.
  • the cooling water through-passage 10 connects a cooling water space 11 of the cylinder head 7 with the annular cooling water sponding bore 13 and 14.
  • the intermediate pipe 17 is provided with a radial collar 18 within the area of the aperture 9.
  • One annular seal 19 and 20 each is arranged between the collar 18, on the one hand, and the separating suraces 1 and 6, on the other, respectively.
  • An internal combustion engine which includes a crankcase, a cylinder head secured at the crankcase by means of cylinder head bolts, said cylinder head and crankcase being provided with mutually facing sepa- V rarting surfaces, spacer means arranged between the cylinder head and crankcase within the area of the cylinder head bolts, liquid-cooled cylinder liner means provided with a radial collar mounted on the separating surface of the crankase facing the cylinder had, a passage being provided for the cooling water between the cylinder head and the crankcase, intemediate pipe -means inserted into said passage and annular seal 3.
