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.
