A cylinder liner for use in an internal combustion engine having a cylinder block with a cylinder bore adapted to carry a piston therein. The liner comprises a body formed from a powdered metal material, the body formed therefrom being rigid and wear resistant. The body comprises a smooth, inner, piston-directing surface; an outer, cylinder bore-contacting surface; and an upper, combustion containing area. A mechanism is provided for improving transfer of heat from the combustion containing area to the cylinder block. A mechanism, disposed within the piston-directing surface, is provided for improving piston scuff resistance while maintaining piston-directing surface smoothness.

Powdered metal cylinder liners

Apparatus is disclosed for producing composite cylinders having cylinder walls comprised of two adjacent diverse layers of metal material which are bonded together by application of radial forces thereto and then sintered to complete the bonding process. Mechanical locking of the layers is achieved by grain interlocking between the two layers of metal material.

Apparatus for producing composite cylinders

A process for fabrication of sintered metal components having improved mechanical, physical and wear-resistent properties.

Process for fabrication of sintered metal components

Powdered metal composition consisting essentially of carbon, copper, solid lubricant particles, carbide-enriched alloys and iron and process for sintering to yield alloyed components exhibiting improved mechanical, physical and wear-resistent properties.
