摘要
简要介绍了三效催化转化器(TWC)的结构和工作原理。为提高三效催化转化器的净化效率,对外部环境的条件提出了要求,即实际空燃比控制在理论空燃比附近、使用高品质的无铅汽油和润滑油、保持发动机良好的工作状态、正确安装三效催化转化器等。
This paper makes brief introduction to the structure and working principle of three way catalytic converter. In order to improve purifying effect of three way catalytic converter on exhaust gas emission, some requirements on outer factors are put forward also,i.e., control the actual air/fuel ratio near the theoretic value, use of superior nonleaded gasoline and lubrication oil, keep of better engine working status, correct installation of three way catalytic converter and etc.
