  • Publication number: 20120058019
    Abstract: A honeycomb filter includes a cell having one open end and another closed end that serves as a fluid flow path and a cell having one closed end and another open end, wherein the cells are alternately disposed. The honeycomb filter includes an undeposited region in an upstream region of a partition portion, which has no trapping layer and has a length of 5% or more and 30% or less of the length of the inlet cell. The upstream region of the partition portion includes an undeposited region having an area of 10% or more of that of the cell in a cross-section perpendicular to the exhaust gas flow direction. The undeposited region with no trapping layer in the upstream region decreases the permeation resistance of the partition portion in the upstream region and facilitates fluid passage through the partition portion in the upstream region.

  • Publication number: 20120017555
    Abstract: In honeycomb filter 20, capturing layers 24 which are layers that capture and remove solid components in a fluid are formed on a porous partition portion 22 that forms a plurality of cells 23 each having one end open and the other end sealed and functioning as a channel of a fluid. The capturing layers 24 are formed so that the thickness has a tendency to decrease from a central region of the honeycomb filter toward an outer peripheral region of the honeycomb filter, the central region and the outer peripheral region being included in an orthogonal plane orthogonal to the cells 23. Accordingly, the fluid is led to flow at the outer peripheral side and more solid components can be captured and removed at the outer peripheral side.
