摘要

The internal combustion engine (1) comprises an exhaust gas recirculation system with an exhaust pipe (2), which is fluidically connected with the internal combustion engine. An exhaust gas treatment device (4) is fluidically connected to the exhaust gas line, which comprises an exhaust gas heating unit (5) in the exhaust pipe in flow direction (3) of the exhaust gas. A secondary auxiliary medium introducing unit (11) is arranged in the exhaust gas heating unit upstream to a diesel oxidation catalytic converter (6).
