Optimized Filter Design and Selection Criteria for Continuously Regenerating Diesel Particulate Traps 1999-01-0468

Upcoming (2005) particulate matter standards for diesel powered vehicles are likely to require the deployment of aftertreatment devices, such as particulate filters to ensure emissions compliance. A major challenge in the development of diesel filter systems has been the achievement of filter regeneration by the oxidation of the collected particulate matter in a reliable and cost-effective manner. Recently the emergence of the so-called continuously regenerating trap (CRT™) in conjunction with the future availability of very low-sulphur diesel fuel, represents a promising solution to the diesel particulate control problem. In the present study, design and selection criteria are devised, regarding the sizing of wall flow diesel particulate filters for application in CRT™ systems, employing a range of analytical and 3-D CFD tools validated against experimental data.
