The invention relates to a palladium ruthenium three-way catalyst which comprises a front-stage catalyst assembly and a rear-stage catalyst assembly, an air inlet flange and an air inlet cone assembly are sequentially arranged above the front-stage catalyst assembly, and a ruthenium-containing catalytic assembly is installed in the front-stage catalyst assembly. A support assembly, an air outlet cone assembly and an air outlet flange assembly are sequentially arranged below the front-stage catalyst assembly assembly. The stage catalyst assembly component is sequentially provided with a rear-stage catalyst component containing ruthenium, a silencer assembly component and a tail section pipe component from left to right. The ruthenium element is innovatively introduced for use, the use amount of the rhodium element is reduced, the cost of an exhaust system can be effectively controlled through the design, the emission reduction effect of the exhaust system is equivalent to that of a traditional three-way catalyst scheme, and forward research and development of automobile enterprises are facilitated.

    本发明涉及一种钯钌三元催化器,包括前级催化器总成组件和后级催化器总成组件,所述前级催化器总成组件上方依次设置有进气法兰和进气锥组件,前级催化器总成组件内安装有含钌元素催化组件,前级催化器总成组件下方依次设置有支架组件和出气锥组件及出气法兰组件;所述级催化器总成组件从左至右依次设置有含钌元素后级催化器组件和消声器总成组件及尾段管组件。本发明创新性引入钌元素的使用,减少铑元素的使用量,这种设计可以使排气系统的成本得到有效控制并与传统三元催化器方案的减排效果相当,利于车企进行正向研发。
