ABSTRACT:
In an internal combustion engine with an exhaust gas recirculation system and an exhaust gas turbocharger having a turbine arranged in an exhaust gas duct and a compressor operated by the turbine and being disposed in an air supply duct for supplying charge air to the engine, an exhaust gas recirculation line extends between the exhaust gas duct upstream of the turbine and the air supply duct and downstream of the compressor. Cooling means are arranged in the exhaust gas duct and heating means are arranged in the air supply duct upstream of the compressor to permit the generation of a pressure differential between the exhaust gas duct and the air supply duct which provides for an exhaust gas recirculation flow through the exhaust gas recirculation line over a large engine operating range.
