  • Cylinder sleeve for an internal combustion engine
    Patent number: 11680538
    Abstract: A cylindrical sleeve for an internal combustion engine is disclosed. The cylindrical sleeve includes a hollow cylindrical sleeve body, extending along an axial direction, with an inner peripheral side that has, along the axial direction, a first axial portion and a second axial portion. The inner peripheral side in the first axial portion is either cylindrical or opens at a first opening angle towards the second axial portion. The second axial portion opens at a second opening angle away from the first axial portion that is greater than the first opening angle. A first surface roughness of the inner peripheral side in the first axial portion is greater than a second surface roughness in the second axial portion.

  • Cylinder liner
    Patent number: 9816456
    Abstract: A cylinder liner for an internal combustion engine may include an outer circumferential surface defined by the cylinder liner composed of a gray cast iron for integrally casting onto a cast material of an engine block. A bonding component may be included for strengthening a bond of the outer circumferential surface to the cast material of the engine block. The bonding component may include at least one of a wire mesh and a wire grid that does not melt during a casting operation of the engine block. The bonding component may be arranged at least in a predefined region on the outer circumferential surface. The bonding component may be welded at least partially to the outer circumferential surface.
