Abstract: In a manufacturing method for manufacturing a dispersion body, a plurality of types of solid particles, water, and a liquid other than water are mixed. The solid particles and the liquid are selected such that Hansen spheres of at least two types of the solid particles and a Hansen sphere of at least one type of the liquid mutually overlap, and a Hansen solubility parameter distance to water of at least one type of the solid particles of which the Hansen spheres overlap that of the liquid is greatest among all solid particles used in manufacturing of the dispersion body, and used to manufacture the dispersion body.

Abstract: In a manufacturing method for manufacturing a dispersion body, a plurality of types of solid particles, water, and a liquid dispersant are mixed. In the manufacturing method, at least two types of the solid particles and at least one type of the dispersant that are selected based on a material type selection method are used, and at least an optimal amount of the dispersant that is determined based on an optimal amount determination method is added and mixed. The material type selection method is based on a Hansen solubility parameter distance to water, Hansen spheres of the solid particles, and a Hansen sphere of the dispersant.

Abstract: An exhaust gas filter purifies exhaust gas containing particulate matter emitted from an engine. The filter has cell walls and cells surrounded by the cell walls. Through pores formed in the cell walls, adjacent cells are communicated. The cells have open cells opening along an axial direction of the filter, and plugged cells. An upstream end part of the plugged cell is plugged by a plug member. On a cross section perpendicular to the axial direction, a flow-passage sectional area of the plugged cells is larger than a flow-passage sectional area of the open cells. A total length of the filter is not less than a first standard value and is not more than a critical length Lm determined by respective predetermined equations.

Abstract: An exhaust gas filter for purifying exhaust gases including particulate matter discharged from an internal combustion engine includes a honeycomb structure whose axial direction matches an exhaust gas flow, a plug portion which selectively plugs upstream end faces of the honeycomb structure which faces the exhaust gas flow, and catalyst carried on the honeycomb structure.The honeycomb structure has a plurality of partition walls and cells surrounded by the partition walls, and pores formed inside partition walls between adjacent cells communicating with each other. The plurality of the cells have open cells which are penetrated in the axial direction and plugged cells having one upstream end which face the exhaust gas flow plugged by the plug portion. The honeycomb structure has a first region which does not carry the catalyst on the partition walls and a second region which carries the catalyst on the partition walls.

Abstract: An exhaust gas purification filter collects PM contained in and purifies exhaust gas emitted from a gasoline direct injection engine. The exhaust gas purification filter has a honeycomb structural body which has a plurality of cells, partition walls and plug members. Each of the cells is surrounded by the partition walls. An opening section of one end of each of the cells is plugged by a plug member. The plug members satisfies a relationship of L/D≦50 and L≦3, where L is an average length (mm) of the plug members and D is an average pore size mm of the plug members. The honeycomb structural body and the plug members are made of cordierite. The cordierite contains silica, talc, kaolin, alumina and/or aluminum hydroxide, etc.
