Definitions

  • the present invention relates to a method for producing a particularly thermally sprayed, thin-walled cylinder liner for insertion into a cylinder crankcase.
  • cylinder liners in internal combustion engines makes it possible to use for the engine block another material, which meets only the relevant requirements.
  • the cylinder liner on the other hand, can be optimized to meet wear resistance and low friction requirements. Since the material content of the liner is relatively small compared to the engine block, higher quality and therefore more expensive materials can be used here, without being too detrimental to the overall cost.
  • the prior art discloses methods for producing light metal cylinder liners for thermal joining in cylinder crankcases made of iron or light metal known (See, for example, the brochure "Overhaul of Aluminum Engines” by MSI Motor Service International GmbH, Edition 03/99). Such bushings are produced, for example, via a process of spray compacting with subsequent mechanical processing. However, these bushings sold under the brand name Alusil® have the disadvantage of a moderate wear resistance on the cylinder surface. Furthermore, a complex process of the exposure of silicon crystals during the finishing of the cylinder running surfaces is necessary here.
  • Aluminum-silicon cylinder liners or cylinder running surfaces made of block alloys (Alusil®, Lokasil®) marketed under the brand name Silitec® have a high thermal conductivity.
  • the wear resistance of the respective cylinder surfaces is determined by the present after honing silicon particles.
  • a maximum silicon content of about 20% can be achieved in terms of process technology.
  • spray-compacted materials higher silicon contents can be achieved; Due to the process, however, this leads to increasing component costs. Due to the high mechanical load of new engines, such as gasoline engines with gasoline direct injection or modern diesel engines, however, the mechanical strength values with conventional aluminum-silicon alloys are borderline.
  • slip-fit liners made of gray cast iron are known as cylinder liners.
  • the liners are manufactured mechanically from centrifuged gray cast iron pipes. To achieve the required surface roughness and cylindrical shape of the outer diameter is ground.
  • To install cast iron bushings it is necessary that the bush has a larger diameter at room temperature than the bore of the cylinder crankcase. Thereafter, the diameter of at least one of the two joining bodies by thermal expansion to change such that the socket can be safely inserted into the cylinder crankcase. This is generally done by heating the cylinder crankcase, as due to the low thermal expansion coefficient of gray cast iron cooling the socket alone is not sufficient. This makes the insertion of gray cast iron bushings consuming and expensive.
