Piston unit for an internal combustion engine, especially for a large diesel engine, comprising at least three main parts located in successive order in the direction of the longitudinal axis of the piston and to be connected to each other. The piston unit includes a uniform upper part (3), which defines, when installed within a cylinder of the engine, a combustion chamber from the side of the piston and which is fixed inside of the piston at its central region to a middle part (2) of the piston unit preferably by means of a screw (4) or the like. At least the main part of, preferably all of the piston ring grooves (7) are arranged on a middle part (2). In addition the upper part (1) is selected to be of a material with better heat resistance than that of the middle part (2) and of a lower part (1).
