ンジン性能の低下を招く。それ故。Conventional technology Diesel exhaust gas filters for collecting soot emitted from diesel engines include filters using metal wire mesh coated with alumina, ceramic foam filters with a porous structure using foaming agents, ceramic fiber mats, A ceramic monolith filter in the form of a ceramic monolithic filter and the like have been devised. Among them, ceramic monolith filters with a /S nicomb shape, which have a soot collection efficiency of 90% or more and a small pressure loss in exhaust gas through the filter, are considered promising as filters for removing soot from exhaust gas.0 From Ceramic Monolith Filters The diesel exhaust gas filter has a honeycomb structure made up of a large number of cells made up of fibers made using an extrusion method that uses cordierite as its main component. The upstream and downstream cell ends of the structure are made of cement-like, very low porosity material with a length of approximately 101) 1m.
are alternately occluded with materials. These upstream and downstream closures divide the cell into inlet and outlet exhaust gas passages. As a result, almost all of the soot in the exhaust gas is collected on the cell walls. As soot accumulates, the pressure loss of the exhaust gas increases in the diesel exhaust gas filter, leading to a decrease in engine performance. Therefore.

有するディーゼル排ガスフィルタが望まれる。In order to maintain good engine performance, a method is used to regenerate the diesel exhaust gas filter by burning the soot once a certain amount of soot has accumulated. A diesel exhaust gas filter is desired that has a honeycomb structure that allows soot to burn smoothly and allows the filter to be easily regenerated many times.

た。In the diesel exhaust gas filter 13 as shown in FIG. do. However, diesel exhaust gas filter 1
In the cell 16 of No. 3, soot gradually accumulates from the entrance. For this reason, the amount of combustion heat generated is large in the exit direction of the filter, that is, closer to the outlet closing portion 19. Therefore, after a certain amount of soot has accumulated in the cell, once the soot 20 at the inlet end is ignited, combustion occurs rapidly, the temperature of the diesel exhaust gas filter rises, and the diesel exhaust gas filter is moved near the outlet where a large amount of soot has accumulated. The problem of melting occurred.

不充分であった。Furthermore, if the ventilation resistance of the exhaust gas passing through the cell walls is reduced, the exhaust gas will flow through the cell with the lowest ventilation resistance among the many cells, and the amount of soot deposited in that cell will also increase. Therefore, the state of soot deposition varied from cell to cell, and as a result, there were cells in which sufficient soot was not deposited. As a result, when the exhaust gas filter was regenerated by combustion, the cells with a large amount of soot accumulated became hot, leading to the destruction of the exhaust gas filter. In addition, cells with a small amount of soot deposited did not combust sufficiently, so that soot was not combusted to adjacent cells, resulting in insufficient regeneration.

、その材料の気孔率を９６係まで上げることができる。The diesel exhaust gas filter 1 is manufactured, for example, by the following method. 30 parts by weight of alumina fibers cut into pieces of 20 mm or less and 16 parts by weight of ceramic raw material powder are suspended in 3,000 parts by weight of water, and an organic binder such as polyvinyl acetate is added to this mixed slurry, followed by a flocculant such as polyacrylamide. A corrugated sheet was created by bonding a corrugated sheet and a flat sheet from the obtained sheet in the same manner as corrugated pole manufacturing. is glued and wrapped around the core to form a honeycomb shape so that the exhaust gas that enters one of the cells of the non-nicum will pass through the cell wall, transfer to other cells, and then be discharged. The inlet and outlet cells of the cam were alternately closed by injecting the same amount of the material described below into each cell. This molded product was fired in the air at 1250"0 to turn the ceramic fibers and ceramic raw material powder into ceramics, thereby obtaining the desired exhaust gas filter with a single comb structure. Add 2 parts by weight of the baked and pulverized inorganic material, 0.1 part by weight of starch, and 2 parts by weight of water to form a paste. Then, add 0.1 part by weight of organic powder in powder form and stir and mix. By injecting such a material, the porosity of the material in the closed part became 60%.The organic powder used here is a synthetic polymer such as polyester and a natural material such as starch. By increasing the mixing ratio to 100 parts by weight of organic powder, which may be either a polymer or a combustible inorganic powder such as carbon particles, the porosity of the material can be increased to 96 parts.

度上昇が局部的に生じることもない。When the porosity exceeds 955% t-, the strength of the material is extremely reduced, making it impractical.The O inlet closing portion 8 is press-fitted to have a larger cross section than the outlet exhaust gas passage 7, and the cell wall is expanded. As a result, the inlet portion 1o of the inlet exhaust gas passage 6 is narrow. The exhaust gas 12 encounters resistance at the inlet, and the exhaust gas flows uniformly into each cell, ie, each inlet exhaust gas passage. Soot is deposited evenly in each inlet exhaust gas passage. Regeneration through combustion has also become sufficient. A large amount of soot does not accumulate in some cells, and there is no damage due to temperature rise.Also, within one cell, soot accumulates uniformly from the inlet to the vicinity of the outlet, so the cell There is no local temperature rise in the wall.
