Abstract

A piston arrangement for a combustion chamber of an internal combustion engine having a variable compression ratio. A piston includes a device for the variable adjustment of the compression ratio associated with the combustion chamber, and a piston pin is coupled to the piston via respective connecting regions, via which piston pin the piston can be coupled to a connecting rod of the internal combustion engine. The device includes the piston pin having at least one eccentric element, which is eccentrically arranged with respect to the connecting regions of the piston pin and via which the piston pin can be coupled to the connecting rod.
