PM Reduction in Diesel Exhaust Gases with a Photocatalytic DPF Reactor 2006-01-0876

The tightening of diesel emissions legislation throughout the EU and US is leading to the development of emission control devices to enable diesel engines to meet the standards. One system which has shown great promise in controlling PM emissions is Diesel Particulate Filter (DPF). Even DPF has showed good filtering efficiency, it has also lots of challenge for serial applications. One of the challenges is regeneration of filtered PM at urban driving condition. Since the temperatures are much lower than those of PM oxidation by itself. Active systems are proposed to ensure the regeneration along variable driving conditions. In this study, Photocatalyst-Plasma and Honeycomb (PPH) is proposed as an active and continuous regeneration system of DPF on the road. The results show a good feasibility of PPH system for PM regeneration with lower power consumption without an increasing pressure on the DPF.
