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.
Claims6
An exhaust turbocharger, comprising:
- an exhaust turbine arranged within a turbine space of a turbocharger housing;
- a compressor arranged within a compressor space of the turbocharger housing;
- and
- an exhaust recirculation line arranged between an outlet from the turbine space to an inlet of the compressor space,
- wherein the exhaust recirculation line is formed at least in part on the turbocharger housing adjacent to the compressor space inlet in a spiral shape.
