Abstract
Silicon nitride (Si3N4) is a good candidate for a DPF substrate due to its excellent mechanical and thermal properties. The novel process for producing porous silicon nitride is established and fundamental characteristics of fabricated Si3N4 honeycomb were evaluated including mechanical/thermal properties and chemical stability against sulfuric acid and several kinds of chemicals. DPF characteristics in application such as pressure drop and soot regeneration behavior were investigated in diesel engine test bench. Numerical studies to evaluate stress in DPF during soot regeneration were also conducted.
