SiC and Cordierite Diesel Particulate Filters Designed for Low Pressure Drop and Catalyzed, Uncatalyzed Systems 2002-01-0322

DPFs (Diesel Particulate Filters) have been a primary technology utilized to purify diesel PM emissions. One of the major challenges of the DPF is to reduce pressure drop caused by PM and ash accumulation.
This paper reports on the definition and investigative results of several major parameters which determine the pressure-drop of Cordierite and SiC (Silicon Carbide) DPF's. After which, the successful material development for low pressure-drop Cordierite and SiC DPF's are presented.
