Abstract:
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.
