    摘要： A filter catalyst is for purifying exhaust gases emitted from internal combustion engines and including particulates, and includes a wall-flow honeycomb structure and an upstream-side straight honeycomb structure. The wall-flow honeycomb structure includes inlet cells clogged on the downstream side of the exhaust gases, outlet cells neighboring the inlet cells and clogged on the upstream side of the exhaust gases, filter cellular walls demarcating the inlet cells and the outlet cells and having pores, and a catalytic layer formed on the surface of the filter cellular walls and/or the surface of the pores of the filter cellular walls. The upstream-side straight honeycomb structure is disposed on the upstream side of the exhaust gases with respect to the wall-flow honeycomb structure, is provided integrally with the wall-flow honeycomb structure, and includes upstream-side straight cells in which the exhaust gases flow straight, and upstream-side cellular walls demarcating the upstream-side straight cells.

    摘要： An exhaust gas filter is capable of suppressing the generation of an excessive pressure loss due to the particulates deposited. At least a part of a multiplicity of cells surrounded by partitioning walls of the honeycombed exhaust gas purification filter have plugs on one of their two end portions. At least a part of the cells to be arranged on the downstream side in the fluid path are partial plugs having openings allowing the fluid flow. The pressure loss caused when the fluid entering the cells passes through the partitioning walls is smaller than the pressure loss caused when the exhaust gas passes through the partial plugs.

    摘要： A ceramic material containing organic binder is formed by extrusion, dried and cut off so as to make the honeycomb body 100 having the bulkheads 11 and a plurality of cells 12 partitioned by the bulkheads 11 and penetrating between both end faces of the honeycomb body 100. The tapered jig 3 having a tapered forward end portion 31 is inserted into the opening 13 of the cell 12 of the honeycomb body 100. Then, the bulkheads 11 are heated and softened and deformed by a pushing force given by the tapered jig 3 so that the opening 13 of the cell 12 is expanded to form the large opening 131, and the opening 13 of the adjoining cell 12 is reduced at the same time so as to form the small opening 132. After that, the honeycomb body 100 is fired. In this way, the exhaust gas purifying filter for collecting particulates is manufactured.
