Abstract

In a waste heat utilization arrangement for an internal combustion engine of a motor vehicle including a waste heat utilization circuit in which a working medium is circulated, a pumping device for pressurizing the working medium, an evaporator for vaporizing the working medium by waste heat of the internal combustion engine, an expansion machine for expanding the working medium while extracting mechanical energy therefrom and a condenser for condensing the working medium in a resting state, the waste heat utilization circuit is in communication with a pressure store capable of maintaining a pressure for setting and ensuring a predetermined adjustable minimum pressure of the working medium in the waste heat utilization circuit.
