| 摘要 |
The invention relates according to a first aspect to an exhaust system for interaction with a combustion engine, comprising a manifold (3) and a supercharger (4) which in its turn comprises a turbine housing (5) having a turbine seat, an outlet opening of said manifold (3) communicating with an inlet opening of the turbine housing (5), furthermore the exhaust system (1) comprises a catalytic exhaust emission control device comprising a first catalyst (9) and a second catalyst (10). According to the invention the first catalyst (9) communicates with an outlet opening of the turbine housing (5), and in that the exhaust system (1) comprises a bypass (11) having a first end that mouth in a point located upstream the turbine seat of the turbine housing (5), said second catalyst (10) and a second flow regulator (12) being arranged in the bypass (11), and a first flow regulator (8) being arranged downstream the point in which the first end of the bypass (11) mouth. According to a second aspect the present invention relates to a method for controlling such a exhaust system, and in a third aspect the present invention relates to a vehicle comprising a combustion engine and such a exhaust system. |
