摘要： PURPOSE:To heighten trap ratio of particulate and to depress increase of pressure loss by increasing gas permeability of wall of a honeycomb structure and making the surface layer exceedingly porous. CONSTITUTION:Cordierite fiber, methyl cellulose, water and lubricant are mixed and kneaded. A honeycomb structure is extruded using a mold that extrudes the mixture, and dried after cutting. Next, the dried product is heated to burn up methyl celllulose and wax, and calcined until the cordierite fibers are sintered together. After cooling, the honeycomb filter thus obtained is held in a metallic case 5 through a metallic heat resisting cushion and made to form a trapper. Consequently, trap ratio of particulate can be heightened and a small-sized filter can be designed easily.

摘要： PURPOSE:To enhance the collection efficiency of fine particles, by using plural piercing holes of a ceramic honeycomb structure molded by extrusion molding as fine pores of partition walls to control the size of the fine pore optionally and easily. CONSTITUTION:A kneaded mixture prepared by keading methyl cellulose and water into a cordierite composition is extruded by a honeycomb molding extrusion die to mold a ceramic honeycomb structure having piercing holes 4 and partition walls 5 as shown by the drawing and the molded one is dried. Subsequently, this structure is cut to a partion wall direction as shown by a broken line to be formed into a shape in the drawing. To this cut structure, holes are provided by drilling by using a drill from a direction A at equal intervals so as to adjust a opening ratio to 35% to form inflow ports and partition walls are provided to other ends of this inflow port. In the next step, holes are provided by drilling in an opening ratio of 30% at equal intervals from a direction B so as not to be directly connected to the inflow ports to form outflow ports and, after partition walls are provided to the other ends of this outflow ports, thus obtained structure is baked to obtain a filter.

摘要： PURPOSE:To equalize an adhering quantity of fine particles in exhaust gas to partitions, by gradually increasing a thickness of the partition from an introducing side end part of the exhaust gas toward its outflowing side end part. CONSTITUTION:Since a filter 20 forms a thickness of its partitions 21 to be gradually increased from the upstream side of the partiton toward its downstream side, length of a passage formed by a space between ceramic frameworks is decreased in the upstream side of the partition, causing flow path resistance of exhaust gas to decrease and its flow quantity to increase. In consequence, a quantity of carbon fine particles adhering to the framework is also increased because a colliding quantity of the exhaust gas increases. On the contrary, the length of the passage formed by the space between the frameworks is increased in the downstream side of the partition 21 due to its large thickness, suppressing a flow of the gas due to an increase of flow path resistance. Accordingly, an adhering quantity of the carbon fine particles to the framework is decreased.

摘要： PURPOSE: To make it possible to regenerate a filter in good efficiency, by partially providing a partition wall through which an exhaust gas is not passed in a filter to uniformly transmit combustion heat to the downstream side by the warmth holding action of said partition wall.
CONSTITUTION: An exhaust gas is flowed into a cell 2 opened at the upstream side and sealed at the downstream side by an embedded seal 4 from the upstream side of a filter 10 and passes a partition wall 5 to be flowed into a cell 1 sealed at the upstream surface by an embedded seal 3 and opened at the downstream side. In this case, fine particles in the exhaust gas are adhered to an collected by the partition wall 5. In the filter 10, a partition wall 6 through which the exhaust gas is not almost passed because adjacent cells 2 are together sealed by the embedded seal 4 at the downstream side is provided. Therefore, when the filter 10 is heated by a heater at the regeneration time of the filter 10, fine particles adhered to the upstream surface of the filter 10 are burnt and, because this combustion heat is transmitted to the further downstream side by the partition wall 6, the fine particles adherd to the downstream side are reheated and regeneration efficiency becomes well.
