Abstract

An engine assembly may include an internal combustion engine, an expander coupled to the engine, a pulley rotatably arranged on a shaft of the expander and coupled to the engine, a coupling device including at least one elastic operating element arranged within an operating element accommodation in an axially deformable manner, a drive disk arranged on the shaft between the pulley and the at least one operating element, and a pressure device connected to the operating element accommodation via a fluid line and configured to apply pressure to the operating element accommodation. The at least one operating element may be deformable in an axial direction such that the at least one operating element adjusts the drive disk into force-transferring contact with the pulley when the at least one operating element is deformed by a pressure applied to the operating element accommodation by the pressure device.
