Abstract: An exhaust turbocharger with a housing, a compressor arranged in a compressor space and an exhaust turbine is arranged in a turbine space, whereby an exhaust line from the turbine outlet is connected to a low-pressure side of the compressor space via an exhaust recirculation line which extends through the housing and is designed largely in a spiral form in the housing. The recirculated exhaust gas flow arrangements improve the dynamics by providing higher turbocharger rotational speeds in the partial load range due to the production of a pre-twist by the exhaust recirculation stream.
