摘　　要：介绍了三效催化剂与红旗CA71 60E型车的匹配试验 ,确定了CA71 60E型车排温曲线及与新车匹配过程中的几个关键技术 ,阐述了三效催化剂的基本工作原理及在不同电脑控制空燃比条件下与不同配方催化剂匹配后整车测试结果 ,排放值达欧洲 1号、In this article,the matching experiment of three-way catalysts with Hongqi CA7160E vechicle was carried out and the emmision temperature curve of CA7160E and the key technologies in the matching process with new vechicles was confirmed. Based on the experimental results,the basic working principle of TWCs,and the results of emission test after matching with different A/F ratios under computer control and different catalyst formulations were expounded.The experiments are successful and the results of emission test can meet the requirements of European standard Ⅰ and Ⅱ.
