汽车催化器的使用对于进一步降低汽车排放具有重要作用。目前,国内有许多单位针对不同的车型研制了多种催化器。由于有些催化器设计不合理造成开发成本过高及产品质量难以保障等问题,加之使用条件的影响,致使国内催化器尚未达到推广应用阶段。针对上述问题,笔者在催化器设计过程中运用并行工程的思想和方法,较为成功地开发出轻型车用催化器。 The use of a catalytic converter plays an important role in further reducing vehicle emissions. At present, many units in China have developed a variety of catalytic converters for different models. Due to the unreasonable design of some catalytic converters, the problems of high development costs and difficulties in guaranteeing the quality of products, coupled with the influence of the conditions of use, the domestic catalytic converters have not yet reached the stage of promotion and application. In response to the above problems, the author in the catalyst design process using the ideas and methods of parallel engineering, the successful development of a lighter vehicle catalyst.
