Abstract:
An exhaust gas purifying catalyst includes an inlet-side catalyst layer formed on an inner side of the partition wall from a surface of the partition wall in contact with an inlet-side cell and formed along an extension direction from an end portion on the exhaust gas inflow side, and an outlet-side catalyst layer formed on the inner side of the partition wall from a surface of the partition wall in contact with an outlet-side cell and formed along the extension direction from an end portion on the exhaust gas outflow side. Here, a sum of the lengths of the inlet-side catalyst layer and the outlet-side catalyst layer is larger than the entire length of the partition wall, and a total amount of an SCR catalyst body present in the outlet-side catalyst layer is larger than a total amount of an SCR catalyst body present in the inlet-side catalyst layer.

Claim (Index 1):
An exhaust gas purifying catalyst of wall flow type disposed in an exhaust pipe of an internal combustion engine and purifying exhaust gas discharged from the internal combustion engine by reacting the exhaust gas with a reducing agent, the exhaust gas purifying catalyst comprising:\n a base of a wall flow structure having an inlet-side cell in which only an end portion on an exhaust gas inflow side is open, an outlet-side cell which is adjacent to the inlet-side cell and in which only an end portion on an exhaust gas outflow side is open, the base further having a porous partition wall partitioning the inlet-side cell and the outlet-side cell; an inlet-side catalyst layer which is formed with a predetermined thickness on the inner side of the partition wall from the surface of the partition wall in contact with the inlet-side cell and which is formed with a predetermined length along an extension direction of the partition wall from the vicinity of the end portion on the exhaust gas inflow side, the inlet-side catalyst layer including an SCR catalyst of a substance which adsorbs the reducing agent and purifies NOx in the exhaust gas; and an outlet-side catalyst layer which is formed with a predetermined thickness on the inner side of the partition wall from the surface of the partition wall in contact with the outlet-side cell and which is formed with a predetermined length along an extension direction of the partition wall from the vicinity of the end portion on the exhaust gas outflow side, the outlet-side catalyst layer including an SCR catalyst of the substance, wherein a sum of the length of the inlet-side catalyst layer and the length of the outlet-side catalyst layer in the extension direction is larger than the entire length of the partition wall in the extension direction, and a total amount of the SCR catalyst body present in the outlet-side catalyst layer is larger than a total amount of the SCR catalyst body present in the inlet-side catalyst layer.
