摘要： The exhaust gas cleaning catalyst according to the present invention is provided with a cylindrical substrate 10 and a catalyst coat layer 20 formed on the surface of the substrate 10. A ratio of the length L in the cylindrical axis direction of the substrate 10 and the diameter D of a cross section orthogonal to the cylindrical axis direction is denoted by (L/D)≦0.8. The coat density of the catalyst coat layer 20 differs between an upstream side portion 10a that includes the exhaust gas inlet-side end 16 of the substrate 10 and a downstream side portion 10b that includes the exhaust gas outlet-side end 18 of the substrate 10. The coat density A in the upstream side portion 10a is lower than the coat density B in the downstream side portion 10b (A

摘要： Particulate filter provided in the exhaust gas purification device includes: a wall-flow part having an inlet-side cell that is open only at an end on an exhaust gas inflow side, outlet-side cell adjacent to this inlet-side cell and is open only at an end on an exhaust gas outflow side, a porous wall partitions the inlet-side cell from the outlet-side cell; a straight-flow part having a through cell that penetrates the filter in axial direction and is open at the end on the exhaust gas inflow side as well as the end on the exhaust gas outflow side. In a cross section of the filter orthogonal to its axial direction, cross-sectional areas of the inlet-side cell and outlet-side cell present in an outer peripheral region of the cross section are larger than cross-sectional areas of the inlet-side cells and the outlet-side cell in a central region of the cross section.
