Abstract: A piston (30) for an internal combustion engine (10) includes a one-piece aluminum piston body (32) including a piston head (34) and a piston skirt (60) adjoining the head (34). The skirt (60) includes a taper (70) narrowing towards the head (32) and defining a major diameter (100) in a first direction normal to a longitudinal piston axis, and a minor diameter (110) in a direction normal to the first direction. The major diameter (100) and minor diameter (110) may have dimensions specified in Table 1, such that scuffing or scratching of the piston (30) is prevented, particularly during engine break-in.

Abstract: Remanufacturing a used cylinder liner (20) includes receiving a used cylinder liner (20) having a fillet (42) relieved of residual compressive stress via service in an engine (10), and compressing a material substrate (23) of the cylinder liner (20) forming a fatigue sensitive fillet (42), such that a non-uniform profile of the fillet (42) is reshaped via plastic deformation of the material substrate (23). Residual compressive stress is restored to the fillet at least in part via the plastic deformation. A mask and used cylinder liner assembly (90) for processing the used cylinder liner (20) during remanufacturing is also disclosed.

Abstract: A repaired piston (610) includes a crown (616) composed of base (634) and welding filler materials (638), and having an annular rim (624) extending around a combustion bowl (622). A finite number of repaired defects (632) are within the annular rim (624), and have a spatial distribution limited by a multidirectional spacing parameter, and a size distribution limited by a unidirectional sizing parameter.
