Exhaust system having N<sub>2</sub>O catalyst in EGR circuit |
| 摘要 |
An exhaust system for an internal combustion engine is disclosed. The exhaust system comprises a particulate filter, one or more NOx reduction catalysts, and a low pressure exhaust gas recirculation (EGR) circuit for connecting the exhaust system downstream of the filter and the one or more NOx reduction catalysts to an intake of the engine. The EGR circuit comprises a N2O-producing catalyst. |

1. An exhaust system for an internal combustion engine, the system comprising a particulate filter, one or more NOx reduction catalysts, and a low pressure exhaust gas recirculation (EGR) circuit for connecting the exhaust system downstream of the filter and the one or more NOx reduction catalysts to an intake of the engine, wherein the EGR circuit comprises a N2O-producing catalyst, and wherein the N2O-producing catalyst comprises manganese supported on an inorganic oxide. |
