Abstract

The invention relates to a device and a method for the recovery of waste heat from an internal combustion engine (2), according to which a feed pump (6), a heat exchanger (8), an expansion engine (10) and a capacitor (12) are arranged in a circuit (4) containing a circulating working medium. A bypass connection (14) is mounted in parallel to the expansion engine (10), in the circuit (4), the expansion engine (10) being coupled to the circuit (4), or decoupled therefrom, according to an operating situation of the internal combustion engine (2).
