The invention relates to a drive train, particularly for a commercial vehicle, - comprising an internal combustion engine that produces an exhaust gas stream; - an exhaust gas line connected to the internal combustion engine; - a supply air line system for supplying a supply air flow for the combustion in the combustion engine, said system being connected to the internal combustion engine; - a steam circuit, comprising an expansion machine, at least one heat exchanger for evaporating the working medium of the steam circuit, and a condenser; - the supply air system comprises a fresh air line for feeding a fresh air flow for the combustion in the internal combustion engine and a recirculating line for recirculating part of the exhaust gas flow to the fresh air side for the combustion in the internal combustion engine. The invention is characterized in that in the recirculating line a plurality of heat exchangers for evaporating the working medium of the steam circuit are provided, and a further heat exchanger for evaporating the working medium of the steam circuit is provided in the exhaust gas line, said further heat exchanger being subjected to an exhaust gas flow intended for being conducted to the ambient area. The working medium of the steam circuit 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, wherein the recirculated part of the exhaust gas flow is first conducted through the first heat exchanger und then through the second heat exchanger and is then cooled. |
