Title:
ハニカム構造体
Document Type and Number:
Japanese Patent JP4616752
Kind Code:
B2
Abstract:
There is provided a honeycomb structure capable of largely inhibiting generation of a crack due to a thermal stress during use and regeneration of a collection filter for an exhaust gas, especially a diesel particulate filter (DPF) which collects particulates in the exhaust gas of a diesel engine, especially a crack (especially, a ring of crack) in an axial direction of the DPF, so that a soot deposit limit can largely be raised. The honeycomb structure includes a bonded honeycomb segment article in which a plurality of honeycomb segments 2 are integrally bonded on mutual bonding surfaces thereof via bonding material layers; and an outer peripheral coating layer which covers an outer peripheral surface of the bonded honeycomb segment article, and the honeycomb structure has a structure in which a plurality of cells constituting fluid channels are arranged in parallel with one another in a central axis direction. In a honeycomb segment 2, solid cells 10 are beforehand arranged in four corners of each of opposite end faces of the honeycomb segment 2 and/or the center of each side of an outer peripheral portion of each of the opposite end faces of the honeycomb segment 2, and the solid cells 10 are integrated with the honeycomb segment 2.
