摘要： A wall-flow-type exhaust gas purification catalyst with an oxygen storage material that has an increased OSC and exhibits its OSC without a compromise provides an exhaust gas purification catalyst having a wall-flow-type substrate, a first catalytic layer and a second catalytic layer. The first catalytic layer is provided to an internal portion of a partition wall in contact with an entrance cell. The second catalytic layer is provided to an internal portion of a partition wall in contact with an exit cell. Each of the first and second catalytic layers has an oxygen storage material. The ratio (D1/D2) of the coating density D1 of the first catalytic layer to the coating density D2 of the second catalytic layer is 1.1 to 1.8.

摘要： Provided is an exhaust gas purification catalyst that combines reduction of pressure loss and enhancement of purification performance. This invention provides an exhaust gas purification catalyst comprising a wall-flow-type substrate and first and second catalytic layers. The first catalytic layer is provided to the interior of a partition wall, in contact with an entrance cell, from an exhaust inlet-side end in the running direction, having a length L1 less than Lw. The second catalytic layer is provided to the interior of a partition wall, in contact with an exit cell, from an exhaust outlet-side end in the running direction, having a length L2 less than Lw. An internal portion of partition wall in contact with entrance cell has a substrate-exposing segment near the exhaust outlet-side end.

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
