Definitions

  • the invention relates to a cylinder crankcase for an internal combustion engine, which is made as a casting from an aluminum alloy.
  • a cylinder crankcase of the generic type is known from DE-Z MTZ Motortechnische Zeitschrift 41 (1980) 5, pages 183 to 189.
  • the cylinder crankcase is made of a hypereutectic aluminum alloy, which is a compromise between castability, machinability, strength and running properties of the pistons in the cylinders.
  • the inside of the cylinders also form the running surfaces for the pistons and are therefore made of the same material as the cylinders themselves.
  • the invention has for its object to provide a cylinder crankcase that in addition to the properties such as high strength, good castability and machinability and good running properties for the pistons in the cylinders can be manufactured inexpensively.
  • the invention is characterized by an inexpensive aluminum alloy for the cylinder crankcase, which has very good machinability with good casting and strength properties.
  • the hypereutectic aluminum alloy used only for the cylinder liners has high wear resistance and high heat resistance, which is therefore suitable for guiding the pistons due to these special properties.
  • 1 denotes a cylinder crankcase of an internal combustion engine.
  • Cylinder liners 3 are let into the cylinders 2 for guiding the pistons (not shown).
  • the cylinder liners 3 are cast or inserted in the cylinder crankcase 1.
  • the outer sides 4 are structured, i.e. provided with grooves, angular elevations or the like.
  • the cylinder crankcase 1 consists of an aluminum alloy with the main alloy components silicon and copper and is produced in the pressure or mold casting process. All Al alloys with a silicon content of 3% to 12% and a copper content of 3% to 5% are suitable.
  • the alloy G-AISi9 Cu3 has particularly favorable properties as a material for the cylinder crankcase 1.
  • the cylinder liners 3 embedded in the cylinders 2 consist of a hypereutectic AISiCu alloy, the alloy AISi1 7Cu4Mg being particularly suitable as a bushing material.
