CYLINDER LINER WITH A CASE ON A CUFF-RING GROOVE

摘要

A cylinder liner (12) for an engine (10) includes a hollow cylindrical sleeve, with an inner surface (22) and an outer surface (24), that extends from a first end to a second end along a longitudinal axis (20). The cylinder liner may also include an annular cuff -ring groove (48), with a radiused fillet region (48a), on the inner surface proximate the first end. The cylinder liner may further include a hardened case (40) formed on the inner surface of the sleeve. The case may extend under a base of the fillet region of the cuff-ring groove.
