Diesel Particulate Filters Made of Newly Developed SiC 2001-01-0192

This paper presents the performance and durability test results of a newly developed diesel particulate filter (DPF) made of silicon carbide (SiC). While SiC offers thermal resistance that is superior to cordierite, it requires a complex, multi-segment bonded design structure due to the thermal expansion coefficient that is higher than cordierite, which leads to a higher thermal stress during regeneration. This company has developed a honeycomb slit-type DPF made from a newly developed SiC through the application of its own honeycomb forming technology and material technology, and has also succeeded in controlling the cost of the product through a simplified design.
