摘要： A method for the production of a multi-part piston for an internal combustion engine involves producing an upper piston part having a piston crown as well as an inner and an outer support element, and producing a lower piston part having a skirt and having pin boss supports and pin bosses connected with the pin boss supports, and an inner and an outer support element. A separate cooling oil collector having at least one cooling oil opening is inserted into the upper piston part or the lower piston part. The upper piston part and the lower piston part are connected in such a manner that the inner and outer support elements of the upper and lower piston parts, delimit an outer circumferential cooling channel and a cavity that is open toward the pin bosses and provided with the cooling oil collector.

摘要： An exemplary piston may include a piston body having radially inner and outer body mating surfaces. The piston may further include a cooling gallery ring cooperating with the piston body to form a continuous upper combustion bowl surface and a cooling gallery. The cooling gallery ring may have radially inner and outer ring mating surfaces abutted along their corresponding radially inner and outer body mating surfaces, such that the cooling gallery is substantially enclosed. The piston body and cooling gallery ring may be joined together along the radially inner and radially outer interface regions to form a generally one-piece piston assembly. The radially outer interface region may be elongated in a direction parallel to the piston axis, e.g., facilitating a laser welding joining process.
