Zusammenfassung:	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.
