Apparatus for recovering energy from an internal combustion engine with an exhaust gas turbocharger as a heat source for a steam engine cycle and method for operating the apparatus

摘要

The invention relates to a device for energy recovery in an internal combustion engine (1), in which an exhaust gas turbocharger (2) of the internal combustion engine (1) is used as a heat source for a steam engine cycle (5) with a steam engine (6) and for this purpose on the turbine housing of the exhaust gas turbocharger (3 ) a heat exchanger (4) is arranged, which is incorporated into the steam engine cycle (5) and / or switched on, and a method for operating the device. The invention is characterized in that the heat exchanger (4) on the turbine housing of the exhaust gas turbocharger (2) is designed and / or arranged to heat the medium in the steam engine cycle (5) before entering the steam engine (6) without phase change, the heat exchanger (4) upstream or downstream of a second heat exchanger (8) in the steam engine circuit (5) and wherein the second heat exchanger (8) in the steam engine cycle (5) with the exhaust pipe (9) of the internal combustion engine (1) is in communication.
