				<content:encoded><![CDATA[<p>三元催化转换器（Three-way Catalyst，TWC)也称为触媒转换器，简称触媒。所谓“三元”，是指能同时处理CO、HC和NOx三种有害气体。安装在排气管中部，排气消声器的前面，一般为整体式。<br />
<strong>1、三元催化转换器的功能</strong><br />
利用转换器中的三元催化剂，将发动机排出废气中的有害气体HC、CO和NOx转变为无害气体H2O、CO2和N2 。<br />

<strong>2、三元催化转换器的结构</strong><br />
【组成】由载体、外壳和隔离层等组成。<br />
载体：载有催化活性层。常用蜂窝状陶瓷作为承载催化剂的载体，在陶瓷载 体上浸渍铂（或钯）与 铑的混合物作 为催化剂。<br />
外壳：一般用钢板制成。<br />
隔离层：载体与钢板壳体之间。<br />
