Beschreibung
Zusammenfassung:	A piston for an internal combustion engine in which a land located immediately above an oil-ring groove and/or a pressure ring groove of the piston is provided with an annular groove-shaped recess at least around an intermediate portion of the land. The annular groove-shaped recess gradually increases in depth from zero upward along the axial direction of the piston to form an oil reservoir.
