Abstract

The invention relates to a drive train, especially for a commercial vehicle, with an internal combustion engine which produces an exhaust gas stream; with an exhaust gas line which is connected to the internal combustion engine; with a supply air line system for supplying a supply air flow for combustion in the internal combustion engine, which supply air line system is connected to the internal combustion engine; with a steam cycle, comprising an expansion machine, at least one heat exchanger in order to evaporate the working medium of the steam cycle, and a condenser; the supply air line system comprises a fresh air line for supplying a fresh air flow for combustion in the internal combustion engine and a recirculating line for recirculating a part of the exhaust gas stream to the fresh air side for combustion in the internal combustion engine. The invention is characterized in that a plurality of heat exchangers for evaporation of the working medium of the steam cycle is provided in the recirculating line, and a further heat exchanger for evaporation of the working medium of the steam cycle is provided in the exhaust gas line which is supplied with an exhaust gas stream intended for being conducted to the ambient environment, and the working medium of the steam cycle is first conducted through a second heat exchanger in the recirculating line, then through the further heat exchanger in the exhaust gas line and then through a first heat exchanger in the recirculating line, with the recirculated part of the exhaust gas stream first being conducted through the first heat exchanger and then through the second heat exchanger, and is then cooled.
