Exhaust system of an internal combustion engine for a motor vehicle with exhaust gas recirculation

摘要

The system has a heat transferring unit (11) decoupled with a heat energy from an exhaust gas situated in an exhaust gas recirculation circuit (5) and coupled into an exhaust gas sealing system (10). The heat transferring unit is arranged in such a manner that an exhaust gas pressure pulsation is transmitted from an exhaust gas inlet to an exhaust gas outlet of the heat transferring unit. Pressure to be present in a regulating device (14) is higher than pressure prevalent in a discharge point of a combustion air supply (2).
