A cylinder liner for insertion into an aluminum internal-combustion engine block may include a cylindrical body of cast iron having a circumferential external surface. The cylinder liner may also have a coating deposited on and surrounding the external surface. The external surface may have a specific roughness, and the coating may include at least 98% by volume of pure nickel, and a remainder composed of impurities.

Cylinder liner for insertion into an engine block, and engine block

A cylinder liner for an internal combustion engine may include a hollow cylindrical body. The body may include an internal surface having a longitudinal/axial length. The internal surface may be divided into at least two portions along the longitudinal/axial length. The at least two portions may respectively include a specific value of roughness and a predefined length.

Cylinder liner for an internal combustion engine

A sliding combination for use in an internal combustion engine may include at least one cylinder liner defining an internal sliding surface and a ring having an external lateral sliding surface. The external sliding surface of the ring may slide in relation to the internal sliding surface of the liner. The external sliding surface of the ring may include a first coating of a physical vapor deposited metal nitride in sliding contact with a second coating of a diamond-like carbon (DLC) material disposed on the internal sliding surface of the liner.

Sliding combination for use in an internal combustion engine

A cylinder for an internal combustion engine may include a metallic cylinder body and an amorphous diamond-like hard carbon film disposed on an internal peripheral surface of the cylinder body. The amorphous diamond-like carbon film may include a roughness ranging from Rz 0.5 &#x3bc;m to Rz 4.0 &#x3bc;m.
