摘要： The exhaust gas cleaning catalyst according is provided with a substrate and a catalyst coat layer formed on a surface of the substrate. The catalyst coat layer is formed as a laminate structure having an upper layer and a lower layer. The upper layer is a Pd-free layer that does not contain Pd, and the lower layer is a Pd-containing layer. In addition, when a region of the lower layer that corresponds to 20% of the length of the exhaust gas cleaning catalyst from the exhaust gas inlet side end towards the exhaust gas outlet side of the exhaust gas cleaning catalyst is divided into four equal regions to be each 5% of the length, the relationship A>B>C is satisfied, where A, B, and C represents the Pd content in the first, second, and third region respectively.

摘要： An exhaust gas purification catalyst that has an excellent exhaust gas purification performance while suppressing pressure loss increases. The exhaust gas purification catalyst is provided with a substrate having a wall-flow structure and having a partition; a first catalyst layer formed, in a region of an interior part of the partition that is in contact with an entrance cell, along the extending direction of the partition from an exhaust gas inflow-side end for less than the total length Lw of the partition; and a second catalyst layer formed, in a region of an interior part of the partition that is in contact with an exit cell, along the extending direction of the partition from the exhaust gas outflow-side end for less than the total length Lw of the partition. The first catalyst layer and the second catalyst layer are configured to partially overlap with each other in the extending direction.

摘要： The exhaust gas purification device is provided with a wall flow structure substrate that has an entry-side cell, an exit-side cell and a porous partition, first catalyst parts which are formed in small pores having a relatively small pore diameter among internal pores in the partition, and second catalyst parts which are formed in large pores having a relatively large pore diameter among the internal pores in the partition. The first catalyst parts and the second catalyst parts each contain a carrier and at least one type of noble metal from among Pt, Pd and Rh supported on the carrier. The noble metal content in the first catalyst parts is smaller than the noble metal content in the second catalyst parts per 1 liter of substrate volume.
