摘　　要：催化剂是整个催化转换器的核心部分,决定催化转换器的主要性能指标。文章详细地介绍了Pd-YCZ紧耦合型催化剂的制备和加工工艺过程,并通过催化转化率、起燃温度、空燃比特性和抗高温老化能力等实验进行性能测试;实验结果表明,研制的Pd-YCZ紧耦合型催化剂性能良好,完全能满足紧耦合型催化剂的使用要求,为紧耦合催化转换器的进一步研制打下了良好的基础。The catalyst is the core part of a catalytic converter, which affects main performance indexes of the catalytic converter. The paper presents the Pd-YCZ catalyst design and processing technological process in detail. Performance tests of the Pd-YCZ catalyst are carried out in terms of the catalyzed conversion rate, combustion temperature, air-fuel ratio characteristic and anti-high temperature ability. The experimental results show that the performance of the Pd-YCZ catalyst is good. As a result, it meets well with the operation requirements of the catalytic converter, and it is valuable for further development of the catalytic converter.
