EXHAUST SYSTEM HAVING NO CATALYST IN EGR CIRCUIT Russian patent published in 2018 - IPC F01N3/20 F01N3/35 B01D53/94

Abstract RU 2675182 C2

FIELD: internal combustion engines.

SUBSTANCE: invention relates to exhaust systems for an internal combustion engine. Present exhaust system comprises a particulate filter, one or more NO_x 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 NO_x reduction catalysts to an intake of the engine. EGR circuit comprises a N₂O-producing catalyst.

EFFECT: low pressure exhaust gas recirculation (EGR) circuit.
