Abstract:
The present invention relates to a piston (10, 110, 210) for an internal combustion engine, having a first piston component (11) and a second piston component (12), which jointly form a circumferential cooling channel (23) that is open toward the second piston component (12), whereby the first piston component (11) forms at least a part of a piston crown (13) as well as an outer circumferential wall (34) of the cooling channel, characterized in that the outer circumferential wall (34) of the cooling channel (23) has a circumferential projection (32) below the piston crown (13), which projection is provided with a circumferential guide surface (33) for coolant, directed radially inward.
