| 摘要 |
The exhaust system for an internal combustion engine (16) comprises at least one turbo- charger (4), an exhaust duct (19) for conducting exhaust gases out of the cylinders (15) of the engine (16), a catalytic converter (12) that is arranged downstream from the turbine (4a) of the turbocharger (4) for selective catalytic reduction, a mixing space (1, 2) that is arranged apart from the exhaust duct (19) and in fluid communication with a source of pressurized gas (3, 6), and means (10, 13) for introducing reducing agent into the mixing space (1, 2). The mixing space (1, 2) is in fluid communication with the exhaust duct (19) of the engine (16) for introducing the mixture of the reducing agent and the pressurized gas into the exhaust duct (19) upstream from the turbine (4a) of the turbocharger (4). The invention also concerns a method for selective catalytic reduction.
