    摘要： An exhaust-gas purifying apparatus (10,11,12,13) includes an outer cylinder (40,41,42,43), a plurality of cylinder-shaped supports (20,30,21,31,22,32,23,33), and a catalytic layer. The cylinder-shaped supports (20,30,21,31,22,32,23,33) are disposed in the outer cylinder (40,41,42,43), and have an outer peripheral surface and an inner peripheral surface. At least two of the neighboring cylinder-shaped supports (20,30,21,31,22,32,23,33) contact with each other with the outer peripheral surfaces. The catalytic layer is loaded on at least one of the outer peripheral surface and inner peripheral surface of the cylinder-shaped supports (20,30,21,31,22,32,23,33). At least one of the cylinder-shaped supports (20,30,21,31,22,32,23,33) has a ring-shaped cross-section with a cut-off (201,211,221,231), and is disposed in the outer cylinder (40,41,42,43) in such an elastically deformed state that it expands in the centrifugal direction. Thus, the exhaust-gas purifying apparatus (10,11,12,13) not only shows a high exhaust-gas purifying ability, but also is good in terms of the assemblage easiness. Moreover, the exhaust-gas purifying apparatus (10,11,12,13) exhibits improved misfire resistance.

    摘要： A catalyst for purifying an exhaust gas includes zirconia particles, and a transition metal layer, covering at least a part of a surface of the zirconia particles in a lamellar manner. It can reduce the emission of particulate materials (i.e., P. M.), such as SOF and sulfates, because the contacting area enlarges between the transition metal layer and materials to be purified.

    摘要： The present invention provides to an exhaust gas purification that has: a base 11 of wall flow structure having inlet side cells 12 in which an end 13 on the exhaust gas inflow side is open and outlet side cells 14 in which an end 15 on the exhaust gas outflow side is open, and a porous partition wall that partitions the inlet side cell and the outlet side cell; and a first catalyst layer 20 and a second catalyst layer 30 disposed in the interior of the porous partition wall 16 so as to be in contact with the inlet side cells 12 and the outlet side cells 14, wherein either one of the first catalyst layer 20 and the second catalyst layer 30 contains an oxidation catalyst but does not contain a reduction catalyst, and the other one contains the reduction catalyst but does not contain the oxidation catalyst; and a ratio of the lengths of the first catalyst layer 20 and the second catalyst layer 30 differs between a surface of the porous partition wall 16 on the side in contact with the inlet side cells 12 and a surface on the side in contact with the outlet side cells 14.
