Abstract
The present invention relates to a multi-piece, in particular at least two-piece, piston () for an internal combustion engine having a longitudinal axis (L), comprising a piston outer part () having a closed piston head (), which in the fitted state defines a combustion chamber, and a piston body () extending axially away from the piston head (), and a piston inner part (), which in the fitted state is connected to a connecting rod. An outer surface () radially defining the piston () is formed exclusively by at least one portion of the piston body () of the piston outer part (). The piston inner part (), viewed in an axial direction, is arranged radially entirely inside the piston body () or its circumferential surface.
