Abstract
Official abstract text for this publication.
A wall flow type exhaust gas purification filter includes a honeycomb structure body and plugging portions. Four inlet opening cells having a substantially hexagonal shape in cross section surround one outlet opening cell having a substantially square shape in cross section, where one side of an inlet opening cell and one side of the outlet opening cell have a substantially same length and are substantially parallel and adjacent to each other. Distance a between the partition wall defining a first side of the outlet opening cell and the partition wall defining an opposed second side is in a range of exceeding 0.8 mm and less than 2.4 mm, and distance b between the partition wall defining a third side of the inlet opening cell and the partition wall defining an opposed fourth side has a ratio to the distance a in a range exceeding 0.4 and less than 1.1.
First claim
Opening claim text (preview).
What is claimed is: 1. A wall flow type exhaust gas purification filter, comprising: a honeycomb structure body including a porous partition wall defining and forming a plurality of cells as through channels of a fluid, which extend from a first end face to a second end face, and plugging portions disposed at the first end face at a predetermined cell of the plurality of cells and at the second end face at remaining cell, wherein the plurality of cells include an inlet opening…
