    Abstract: A multi-part piston for an internal combustion engine has an upper piston part having a piston crown, and a lower piston part having pin boss supports and pin bosses connected with them. The upper piston part and lower piston part each have an inner and an outer support element, which delimit an outer circumferential cooling channel. The inner support elements delimit a cavity that is open toward the pin bosses, and the cavity is provided with a separate cooling oil collector that has at least one cooling oil opening. In a method for producing a piston, the upper and lower piston parts are manufactured, the cooling oil collector is inserted into one of the upper and lower piston parts in a region of the cavity, and the upper and lower piston parts are connected together at their support elements.

    Abstract: A method for the production of a piston for an internal combustion engine, having a circumferential cooling channel, whereby a blank of a lower piston part is forged, and a blank of an upper piston part is produced, the blanks are pre-machined and joined together to form a piston blank, which is finished to produce a piston. At least one depression or recess is formed into the blank of the lower piston part during the forging process. In the finished piston, the depression forms an opening for a coolant inflow and/or a coolant outflow, or the recess forms an excavation groove for a pin securing ring, respectively.
