Abstract (en)
[origin: WO2010130317A2] The invention relates to an exhaust gas heat utilization device (1) in a motor vehicle using an exhaust gas heat utilization cycle (2) in which a working temperature of a working fluid of the exhaust gas heat utilisation cycle (2) is controlled. The working temperature (T1, T2, T3) is controlled by adapting a mass flow of the working fluid flowing through the heat exchanger (5) of the exhaust gas heat utilisation cycle (2) such that a maximum permitted working temperature, in particular the decomposition temperature, of the working fluid is not exceeded.
