摘要： The present invention is intended to ensure the improvement in catalytic performance of an exhaust gas catalytic converter, which is an essential performance thereof, ensure the thermal resistance thereof and downsize the converter, i.e., improve the arrangeability thereof. The exhaust gas catalytic converter has an upstream catalyst and a downstream catalyst which are arranged in upstream and downstream sides of an engine exhaust passage through which exhaust gas flows. Each of the upstream catalyst and the downstream catalyst contains an oxygen storage component. The oxygen storage component in the upstream catalyst has a structure in which Rh atoms are placed at or between crystal lattice points of a mixed oxide containing Ce and Zr and has a larger amount of oxygen storage than the oxygen storage component in the downstream catalyst under the same temperature conditions.

摘要： In the exhaust gas purifying catalyst (3), palladium is contained as a catalytic component and cerium oxide and (Ce, Pr) compound oxide is contained as a promoter. Now, the weight ratio of cerium oxide to (Ce, Pr) compound oxide is set between 9/1 and 7/3, and the ratio of praseodymium to cerium in the (Ce, Pr) compound oxide is set between 3 mol % and 50 mol %. In this way, because in this exhaust gas purifying catalyst (3), palladium with high low-temperature activity is used for a catalytic component, the exhaust gas purifying performance at low temperature is improved. And because cerium oxide and (Ce, Pr) compound oxide improves catalytic activity of palladium at high temperature, the exhaust gas purifying performance at high temperature, in particular, NOx purifying performance, is improved.
