Passive regeneration is an approach used to oxidise particulate matter (PM) in the diesel particulate filter (DPF) [1]. It uses normal exhaust temperatures and nitrogen dioxide (NO2) as the catalyst to oxidize PM in the DPF. PM was collected from a medium duty diesel engine running at 3500rpm and full load operation. At this steady state condition, the exhaust temperature was higher than 500°C. For the physical and chemical characterization of the particles, PM was sampled at engine out (B-DPF), after the DPF (A-DPF) and after the selective catalytic reactor (A-SCR).

Abstract
Passive regeneration is an approach used to oxidise particulate matter (PM) in the diesel particulate filter (DPF) [1]. It uses normal exhaust temperatures and nitrogen dioxide (NO2) as the catalyst to oxidize PM in the DPF. PM was collected from a medium duty diesel engine running at 3500rpm and full load operation. At this steady state condition, the exhaust temperature was higher than 500°C. For the physical and chemical characterization of the particles, PM was sampled at engine out (B-DPF), after the DPF (A-DPF) and after the selective catalytic reactor (A-SCR).File in questo prodotto:
