Abstract

See full text

A method and apparatus for high-pressure end exhaust gas recirculation on a supercharged internal combustion engine which is relatively simple, low in cost and increases the efficiency of the engine. This is achieved by a third exhaust gas flow of the internal combustion engine expanding separately from a first exhaust gas flow and by providing power to compress a second exhaust gas flow. For this purpose, a turbine is arranged as the drive for the exhaust gas compressor. The exhaust gas duct system has a third exhaust gas duct connected to the turbine.
