Description:
The problem of particulate pollution from diesel engines, particularly those used in trucks and buses, has received considerable attention from EPA, CARB and the public. This resulted in emission standards for diesel trucks and buses to take place in 1991 and 1994. Among various alternatives to comply with these standards, the proposed Diesel Emission Oxidizer (DEO) system is emerging as one of the most promising particulate trap technologies.As a result of Phase I work, the radical wire mesh design demonstrated very high soot collection efficiency at a low pressure drop. Moreover, a regeneration scheme employing feed-back control logic is emerging as reliable and cost effective. The design evolved at the end of Phase I has a few innovative ideas such as a continuous thermocouple, en- hanced wire mesh reactor design, upgraded butterfly valve and bypass design and a thermal relief valve.
The majority of work in Phase I Concentrated on the regeneration scheme. Phase II will emphasize the regenera- tion process in further detail and will target issues such as the wire mesh heat transfer properties, flame quenching, wash-coat and base-metal catalyst, thermal relief valve, closed-loop logic enhancements, reliability and the associ- ated economic analysis and impact for new and retrofitting applications. Phase II also includes the development of a finite-difference computer code, analytical studies, proto- types and subsystem testing, and multiple regenerations.
