摘要

The system has an exhaust gas line (2) and a fresh air line (3) that are connected by an exhaust gas recycling pipeline (4), where an exhaust gas cooler (5) and a thermo-electric generator (6) are arranged in the recycling pipeline. The generator is cooled by ambient air and is arranged before the cooler in a flow direction of the exhaust gas. A flow section for the exhaust gas is expanded before the generator in the flow direction and a flow guiding unit are arranged in a diffuser.
