    摘要：本文主要针对三效催化器中衬垫所含有机粘合剂对轻型汽车排放在双怠速排放测试中所产生的影响进行研究，对不同有机粘合剂含量的三款衬垫进行双怠速排放测试，并选取其中一款衬垫进行预处理，清除部分有机粘合剂后再进行排放测试，通过测试结果进行对比分析，综合评价有机粘合剂的含量对排放的影响。

    Abstract: This paper mainly studies the effect of organic binder content contained in the three-way catalytic converter mat on the light vehicle emission during double idling emission test, and conducts double idling speed emission contrast test by comparing three supporting mats with different contents of organic adhesive. Basing on a mat that has been pretreated by removing organic adhesive before double idling emission test, we compare and analyze test results, and comprehensively evaluate the effect of the adhesive content on vehicle emission.
