摘要： The formation of H2S in a stoichiometric or reducing atmosphere is restrained without using Ni or Cu as an environmental load substance. An additional oxide composed of an oxide of at least one kind of metal selected from the group consisting of Bi, Sn and Zn was added to a three-way catalyst for purifying an exhaust gas emitted from an internal combustion engine of which the combustion is controlled in near a stoichiometric atmosphere in the amount of from 0.02 mol to 0.2 mol per liter of the catalyst. The additional oxide forms SO3 or SO4 from SO2 in an oxidizing atmosphere, and stores sulfur components as a sulfide in a reducing atmosphere so that emission of H2S can be restrained. And since no environmental load substance is contained, the catalyst can be used safely.

摘要： The air/fuel ratio (A/F) controller for an internal combustion engine having an upstream catalyst, a hydrocarbon-adsorbent exhaust purification (HAEP) catalyst that is disposed downstream from the upstream catalyst, an upstream A/F sensor disposed upstream from the upstream catalyst, a downstream A/F sensor disposed downstream from the HAEP catalyst, a middle A/F sensor disposed between the upstream catalyst and the HAEP catalyst, an A/F main feedback (F/B) control unit, and an A/F sub-F/B control unit. The A/F main F/B control unit performs main F/D control such that the exhaust A/F detected by the upstream A/F sensor is kept at a specific main F/B target A/F. The A/F sub-F/B control unit performs sub-F/B control such that the exhaust A/F detected by the downstream A/F sensor is kept at a specific sub-F/B target A/F during hydrocarbon desorption from the HAEP catalyst.

摘要： The present invention is directed to address the following problem: in an exhaust gas purification catalyst comprising a dual catalyst of a combination of a startup catalyst and an underfloor catalyst, reduction in the gas diffusivity of the underfloor catalyst results in reduction in the use efficiency of a catalytic active site, resulting in reduction in purification performance. The present invention relates to an exhaust gas purification catalyst comprising a dual catalyst of a combination of a startup catalyst and an underfloor catalyst having a catalyst coating where a large number of voids are included, wherein high-aspect-ratio pores having an aspect ratio of 5 or more account for a certain rate or more of the whole volume of the voids, to thereby enhance the purification performance of the catalyst.
