    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: An engine control device, which is adapted for an engine provided with an NOx-absorbing material arranged in an exhaust passage for absorbing NOx in an oxygen-rich atmosphere, and releasing NOx and absorbing sulfur content when the oxygen concentration drops, includes a discriminator for judging whether the amount of sulfur absorbed by the NOx-absorbing material has reached a prescribed quantity, and a reductant concentration controller which increases the temperature of the NOx-absorbing material by decreasing a quantity related to EGR ratio for desulfurizing the NOx-absorbing material based on the result of judgment made by the discriminator. When the quantity related to the EGR ratio is decreased, the temperature of exhaust gas increases. Consequently, the temperature of the NOx-absorbing material increases and the sulfur in the NOx-absorbing material is freed and released.
