Abstract (en)
[origin: WO2013104633A1] An exhaust system (2) for reducing particulate and NO2 emissions from diesel engine exhaust gases comprises: a diesel particulate filter (10); an inlet (6) for receiving exhaust gases from a diesel engine; a first conduit (4) capable of providing a first fluid connection between the inlet (6) and the diesel particulate filter (10); a second conduit (12) capable of providing a second fluid connection between the inlet (6) and the diesel particulate filter (10); a diesel oxidation catalyst (14) in the second conduit (12), the diesel oxidation catalyst catalysing hydrocarbon combustion and the formation of NO2 and having high HC activity and high NO2 activity; a valve mechanism (18) for selectively directing exhaust gases from the inlet (6) to the diesel particulate filter (10) through the first conduit (4) or the second conduit (12); wherein exhaust gases that pass from the inlet (6) to the diesel particulate filter (10) through the first conduit (4) but not the second conduit (12) will not encounter a diesel oxidation catalyst; and a fuel injector (16) for injecting fuel upstream of the dieseloxidation catalyst (14).
