摘要： A Ce—Zr mixed oxide is employed as an oxygen storage component for a lean-NOx catalyst, and catalytic precious metal atoms are placed at and/or between crystal lattice points of the mixed oxide. This structure prevents the sintering of the precious metal and accelerates movement of oxygen ions in each of crystallites of the Ce—Zr mixed oxide to increase the oxygen storage/release amount of the mixed oxide, which enhances the NOx removal performance of the catalyst.

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： Disclosed is a particulate filter regenerating system which comprises a fuel injection device (7) adapted to inject fuel into a combustion chamber of an engine body (1), and an exhaust gas temperature-adjusting device (33) adapted, when a PM deposit amount which is an amount of particulate matter (PM) deposited in a DPF (particulate filter) 13 provided in an exhaust passage of an engine, reaches a predetermined value X, to cause the fuel injection device (7) to perform a post-injection for injecting fuel into the combustion chamber during an expansion stroke of the engine, so as to execute a filter regeneration process of raising a temperature of exhaust gas flowing into the DPF 13 to burn the deposited PM. The exhaust gas temperature-adjusting device (33) is operable to cause the fuel injection device (7) to stop performing the post-injection in a stage where a PM burning amount which is an amount of PM burned through the filter regeneration process, is less than an initial PM deposit amount which is the PM deposit amount X at a timing of initiation of the filter regeneration process, by a predetermined amount. The particulate filter regenerating system of the present invention can adequately burn and remove PM deposited in a particulate filter, by means of a post-injection of fuel, while effectively suppressing a fuel consumption due to the post-injection.
