Definitions

  • the invention relates to a cylinder crankcase according to the preamble of patent claim 1.
  • GB-A-2 010 394 deals with a cylinder crankcase for a multi-cylinder internal combustion engine in the cylinder of which iron-metallic cylinder liners are provided.
  • the cylinders are separated by partitions running transversely to the longitudinal direction of the cylinder crankcase and are partially surrounded by cooling water channels. Slots are provided in the partitions, which are introduced from the parting plane between the cylinder head and the cylinder crankcase.
  • the object of the invention is to implement targeted thermal expansion measures on a cylinder crankcase comprising a plurality of cylinders and equipped with cooling water channels and made of a light metal alloy. It should be ensured, however, that the stability of the cylinder crankcase is maintained despite these measures.
  • the thermal expansion slots compensate for the temperature tolerances occurring during operation of the internal combustion engine on the cylinder crankcase - it consists of a light metal alloy - and mechanical wear, for example caused by the entry of cooling water into the thermal expansion slots Cavitation, due to the elastic sealant between the cooling channels and the thermal expansion slots is counteracted.
  • This can be achieved in a simple manner by means of the sealing body or the cushion-like plastic filling the thermal expansion slots.
  • the cylinder crankcase 1 is part of a reciprocating internal combustion engine, not shown, with a plurality of cylinders of the series type, which works in the four-stroke process.
  • the cylinder crankcase 1 is made of a light metal alloy, iron-metallic cylinder liners 4, 5 being inserted into the individual spaced cylinders 2, 3. 6 and 7 denote the central axes of the cylinders 2, 3.
  • the cylinders 2, 3 are surrounded by cooling water channels 8, 9 over a substantial portion.
  • the cylinder crankcase 1 is delimited by a parting plane 10, which extends between said housing and a cylinder head 11 (FIG. 4).
  • a cylinder head gasket is designated by 12.
  • heat-emitting combustion spaces are provided by the upright partitions 13 - they also separate the cooling water channels 8, 9 in the area of the cylinder crankcase - between the cylinders 2, 3 are subject to special temperature stresses.
  • 13 thermal expansion slots 14 are provided in the dividing walls running transversely to the longitudinal direction C-C. Milling, sawing or the like are introduced. It is sufficient if the thermal expansion slots 14 are approximately between 0.4 and 0.8 mm - dimension B - wide (FIG. 2) and approximately 20 mm deep - dimension C - (FIG. 1).
  • the thermal expansion slots 14 open with their two ends 15, 16 into the cooling water channels 8, 9. So that the webs 17, 18 of each partition 3 are not damaged by cavitation during operation of the internal combustion engine, the thermal expansion slots 14 are sealed against water ingress from the cooling water channels 8, 9. This can be done by essentially filling the thermal expansion slots 14 with a cushion-like plastic 19 (FIG. 2), for example silicone.
  • the plastic 19 can be introduced by casting or a similar method.
  • sealing bodies 20, 21 are provided in the region of the ends 16, 17 of the thermal expansion slots 14, which are made of elastomer or plastic and prevent cooling water from entering the thermal expansion slots 14.
  • the sealing bodies 20, 21 have a circular cylindrical basic shape and are fixed in corresponding bores 22, 23 which run parallel to the central axes 6, 7 of the cylinders 2, 3.
