Design Optimization of Wall Flow Type Catalyzed Cordierite Particulate Filter for Heavy Duty Diesel 2005-01-0666

This paper reports on the desired performances for Catalyzed Soot Filters (Hereinafter referred as “CSF”), which is composed of a Diesel Particulate Filter (DPF) coated with an Oxidation Catalyst, its design factors and their influence on DPF performance, and on the lifetime prediction method to effectively design a DPF for durability. Performance means pressure drop, Particulate Matter (PM) regeneration limit, time for light-off, and canning strength. Design factors include cell structure, overall DPF size and material porosity. Knowing the relationships between performance and design factors assist the engineer in optimizing the selection of material, cell structure and size of the DPF.
