Beschreibung
Zusammenfassung:	An arrangement for converting thermal energy from lost heat of an internal combustion engine into mechanical energy includes a working circuit for a working medium. An expansion engine is disposed in the working circuit. A heat exchanger is mounted upstream of the expansion engine in a flow direction of the working medium where the working circuit extends through the heat exchange. The heat exchanger includes an exhaust gas recirculation heat exchanger having a cold part and a warm part, an exhaust gas heat exchanger, and a phase transition cooling in the internal combustion engine. The heat exchanger is formed by serial connection in a sequence of the cold part of the exhaust gas recirculation heat exchanger, the exhaust gas heat exchanger, the phase transition cooling in the internal combustion engine, and the warm part of the exhaust gas recirculation heat exchanger.
