Miniaturization Study of Diesel Particulate Filter with Low Pressure-drop

Abstract

Miniaturization of Diesel Particulate Filter (DPF) investigated without exacerbate of fuel consumption and regeneration performance. Application of thinning of soot trap wall, octagonal square cell structure and surface membrane layer realized the DPF with low pressure drop. It reduced temperature difference inside the DPF during regeneration process that decreasing of heat capacity and using of silicon carbide which has high heat conductivity as structure.
