摘要： In a catalyst element for purifying exhaust gases having a metallic carrier and a catalyst carrying layer, an undercoat layer is formed by coating the surface of the carrier with a heat resistant inorganic oxide which is superior in adhesion to a metal. The catalyst carrying layer is then formed by carrying platinum (Pt) and rhodium (Rh) on an alumina layer. The catalyst carrier layer can thus be adhered in a close and better contact with the carrier via the undercoat layer. Even when the carrier is subjected to thermal expansion and vibrations, the amount of peeling of the platinum and rhodium off (or away from) the carrier can be minimized. Consequently, the decrease in the purifying characteristics can be minimized.

摘要： A process for removal of carbon monoxide, hydrocarbons, and nitrogen oxides from the exhaust gas from lean-burn, diesel and other engines which produce exhaust gases containing excess oxygen is disclosed. An exhaust gas from an engine operating at an air-fuel ratio above about 18 is contacted with a multi-component catalyst having at least two catalytic components, each capable of reducing nitrogen oxides within a range of exhaust gas temperatures that is different from the range of exhaust gas temperatures within which each other component is capable of reducing nitrogen oxides. Oxidation of the remaining reducing gases is also accomplished. One example of a two catalytic component catalyst of this invention has a first component of Au supported on alumina, which reduces nitrogen oxides at exhaust gas temperatures between about 600° C. and 900° C., and a second component of Pt supported on Y-zeolite, which reduces nitrogen oxides at exhaust gas temperatures below 600° C.; an example of a three catalytic component catalyst of this invention has a first component of CoO supported on &ggr;-alumina, which reduces nitrogen oxides at exhaust gas temperatures above about 475° C., a second component of an alloy of Pt, Rh and Co supported on BaO2-stabilized &dgr;-alumina, which reduces nitrogen oxides at exhaust gas temperatures between about 315° C. and about 475° C. and a third component of an alloy of Pt and Rh supported on &ggr;-alumina, which reduces nitrogen oxides at exhaust gas temperatures between about 200° C. and about 425° C.

摘要： The Rh content by percentage in an HC absorbent catalytic converter provided in an exhaust pipe is greater than the Rh content by percentage in an upstream three-way catalyst. In this way, even when HC which has been temporarily absorbed is emitted in an atmosphere and the exhaust gas becomes rich, the HC absorbent catalytic converter displays improved oxidization and removal of HC due to the high content by percentage of Rh which has a high HC conversion ratio in rich atmospheres. There is no necessity to control the air-fuel ratio to a strongly lean ratio and so HC removal can be improved while maintaining suppression of NOx emissions.
摘要翻译：在排气管中设置的HC吸收式催化转化器中的Rh含量大于上游三元催化剂中的Rh含量百分比。这样，即使临时吸收的HC在气氛中排出并且排气变浓，则HC吸收催化转化器由于具有高HC含量的Rh的高含量而显示改善的HC的氧化和除去丰富的气氛中的转化率。不需要将空燃比控制为强的稀薄比例，因此可以在保持NOx排放的抑制的同时提高HC去除率。
