text: A honeycomb structure comprising: porous partition walls separating and forming a plurality of cells extending between two end faces, and an outer peripheral wall formed unitarily with the partition walls; wherein the cells include outermost peripheral portion partial cells each locating in an outermost peripheral portion of the honeycomb structure and having an incomplete cell cross section, a part of which is brought into contact with the outer peripheral wall, and complete cells each having a complete cell cross section other than the outermost peripheral portion partial cells; the complete cells and the outermost peripheral portion partial cells having plugging portions formed on one end portion in such a manner that an entire end face of the honeycomb structure shows a checkerwise plugging pattern, and the depth of the plugging portions in the outermost peripheral partial cells is smaller than that of the plugging portions in the complete cells (first plugged honeycomb structure).
text: According to a ninth invention of the present invention, there is provided a honeycomb structure such that in any one of the first to eighth inventions, the cells each have a plugged portion in an open end on an inlet end face side and in an open end on an outlet end face side, and the plugged portions are alternately arranged.
text: The plugging portions were formed so that the respective end faces of each of the dried forms gave a checkerboard pattern by the cells having plugging portions formed on the open ends and the cells having no plugging portions formed on the open ends.
text: If only inhibition of a breakage upon canning is taken into consideration, it is desirable that all the outermost peripheral portion partial cells requiring plugging have plugging portions whose depth is smaller than that of the plugging portions of the complete cells.
text: The present invention relates to a honeycomb structure used for a diesel particulate filter or the like and having cells each having a plugged and portion.
text: wherein the cells include outermost peripheral portion partial cells each locating in an outermost peripheral portion of the honeycomb structure and having an incomplete cell cross section, a part of which is brought into contact with the outer peripheral wall, and complete cells each having a complete cell cross section other than the outermost peripheral portion partial cells; wherein the complete cells have plugging portions in one end portions in such a manner that an end face of the honeycomb structure shows a checkerwise plugging pattern; outermost peripheral portion partial cells having a cell area ratio obtained by the following formula (1) of less than S 1 are formed unitarily with the outer peripheral wall so that the cells may be plugged over the entire length thereof; outermost peripheral portion partial cells having the cell area ratio of more than S 2 (S 1 <S 2 ) have plugging portions formed to have a depth smaller than that of the plugging portions of the complete cells; and outermost peripheral portion partial cells having the cell area ratio of S 1 or more and S 2 or less include cells formed unitarily with the outer peripheral wall so that the cells may be plugged over the entire length thereof and cells having plugging portions formed to have a depth smaller than that of the plugging portions of the complete cells (second honeycomb structure).
text: In the second plugged honeycomb structure 2 of the present invention, the complete cells 6 have plugging portions 8 formed on one end portion in such a manner that each of the end faces of the honeycomb structure shows a checkerwise plugging pattern like a plugged honeycomb structure conventionally used for a filter such as a DPF.
text: Further, the outermost peripheral portion partial cells 5 whose cell area ratio is S 1 or more and S 2 or less include both the cells formed unitarily with the outer peripheral wall 4 so as to be plugged over the entire length and the cells having plugging portions 7 whose depth is smaller than that of the complete cells 6 in one end portion thereof according to the plugging pattern described above.
text: Further, in the outermost peripheral portion partial cells 5 having cell area ratios where the difficulty in forming plugging portions is moderate, both the cells having plugging portions 7 having small depth and the cells formed unitarily with the outer peripheral wall 4 are present.
text: According to a thirteenth invention of the present invention, there is provided the honeycomb structure type catalyst such that in the twelfth invention, the honeycomb substrate has a porosity of 50 to 80%, and an average pore diameter measured by a mercury porosimeter of the cell partition walls and the outer portion of the honeycomb substrate is 10 to 25 μm, and the cells of the honeycomb substrate each have a plugged portion in an open end on an inlet end face side and in an open end on an outlet end face side, and the plugged portions are alternately arranged.
text: 1 and FIG. 2 , there is shown an example of the case where the honeycomb structure 1 is used for a PM collecting filter such as GPF, and accordingly, the cell 5 a has a plugged portion 9 formed at the open end on the inlet end face 11 side and the adjacent cell 5 b has a plugged portion 9 formed at the open end on the outlet end
text: The complete cells 6 and the outermost peripheral portion partial cells 5 have plugging portions formed on one end portion in such a manner that an end face of the honeycomb structure shows a checkerwise plugging pattern like a plugged honeycomb structure conventionally used for a filter such as a DPF.
