  • Finish for cylinder liners
    Patent number: 4862864
    Abstract: A finish for a cylinder liner is provided by first treating the entire inner surface area of the cylinder liner to form a base porosity. An abrasive media is then applied only to portions of the inner surface area to create an extremely light break-in surface, preferably in a pattern such that at any axial location of a piston ring in the cylinder, its periphery is in contact with both the areas of the break-in surface as well as the areas of base porosity to which the break-in surface has not been applied.
    Type: Grant
