HONEYCOMB FILTER
Document Type and Number:
WIPO Patent Application WO/2016/129643
Kind Code:
A1
Abstract:
A partition 201Wio between an inlet passage 210 and an outlet passage 220 in a honeycomb structure 201 has roughness on the inner surface of the inlet passage 210. The honeycomb structure 201 has an outlet passage-side section R2 extending up to a depth D from the surface of the outlet passage 220 (where D is half of the minimum thickness of the partition 201Wio), and an inlet passage-side section R1 between the outlet passage-side section R2 and a plurality of inlet passages 210. If ε1 is the porosity of the inlet passage-side section R1, and ε2 is the porosity of the outlet passage-side section R2, ε1>ε2 is satisfied.
