Abstract
A method of forming an engine is provided. A liner is cast with an outer surface with a first texture extending circumferentially from a first end to a second end of the liner. A section of the outer surface of the liner is machined to provide a second texture extending circumferentially about the liner and spaced apart from the first end, wherein the second texture has a lower specific surface area than the first texture. An engine and a cylinder liner for the engine are provided. The liner has first and second ends with an outer surface extending therebetween. An outer surface of the liner has axial sections defining different textures to form material interfaces with the block with different thermal conductivities thereacross.
