摘　　要：三元催化转化器作为汽油车排气系统常用的后处理装置之一,其失效对排气系统的污染物排放产生巨大影响。然而,相关研究进展的系统总结仍然缺乏。基于此,本文总结国内外三元催化转化器失效的研究进展,从壳体失效、催化剂失效等两个方面进行分析,及综述了催化剂失效的解决方法,为其后续的优化设计提供参考。Three-way catalytic converter is one of the most commonly used post-processing devices in the exhaust system of gasoline vehicles.Its failure has great influence on the emission of pollutants in the exhaust system.However,systematic summaries of relevant research progress are still lacking.Based on this,this paper summarizes the research progress of ternary catalytic converter failure at home and abroad,analyzes from two aspects,such as shell failure and catalyst failure,and summarizes the solution of catalyst failure,so as to provide reference for the subsequent optimization design.
