Definitions

  • the invention relates to an internal combustion engine with a cylinder crankcase in which liners for the pistons are supported in receptacles via guide rings.
  • crankcase expands elastically, more in the transverse direction than in the longitudinal direction.
  • the liner can expand accordingly or is elastically deformed, which leads to the fact that the liners become oval in operation in their barrel diameter for the pistons.
  • the object of the invention is to provide a liner in a cylinder crankcase of an engine, in particular a diesel engine, which enables a constant change of location of the ring joints.
  • each guide ring of the liner has an approximately the dimension of the elastic expansion of the cylinder crankcase in the transverse direction and in the region of the receptacle corresponding ovality with an outer diameter that is larger than the outer diameter of the guide ring in the longitudinal direction.
  • the larger diameter of the guide ring is provided in the transverse direction of the engine, in which the crankcase has its maximum extension. This has the effect that when the crankcase is expanded, the liner becomes almost round again in cross section.
  • the ovality of the guide ring on the liner can be achieved in a simple manner on oval turning machines or by radial tensioning of the liner.
  • a measurement can be made on a conventional type liner, and this measurement is the basis of the ovality of the guide ring on the liner.
  • liners 2 for pistons of an internal combustion engine are used in receptacles 6.
  • the bushings 2 are axially supported on the end of the housing 1 by a collar 3. Radial support of the liner 2 on the housing takes place via a guide ring 4, which is separated from the front collar 3 via a fillet 5.
  • the housing 1 has a greater elastic expansion in the transverse direction in a vertical plane y-y than in the longitudinal direction in a vertical plane x-x. This causes the liner 2 to deform and the inner diameter of the bore 7 of the liner 2 to also deform oval.
  • the guide ring 4 has a defined ovality with an outer diameter D which is larger in the transverse direction (plane y-y) than the diameter D1 in the longitudinal direction (plane x-x).
  • the outer diameter D of the guide ring 4 is larger than the outer diameter D1 in the longitudinal direction (plane xx).
  • the size of the ovality of the ring 4 is in each case dependent on the elastic expansion of the housing 1, so that the Inner diameter d of the liner during operation of the internal combustion engine is almost round again in cross section or within the permissible tolerance range.
