催化转化器评价试验方法初探

Study on the Catalytic Converters Evaluation Program

催化转化器作为一种机外净化装置,已在国外得到了广泛地应用,并被认为是唯一能使车辆排气满足US′83和1985卢森堡协议标准的排气控制装置。本文就转化器的性能及对发动机性能影响等方面进行了分析;介绍了国外推荐考核方法;结合国情提出了我国催化转化器评价试验方法。

The catalytic converters, a typical exhaust aftertreatment device, have been used extensively and have been identified as the only emission control device possible of making exhaust gas in compliance with US' 83 and Luxembury 1985 Agreement standards. In this paper, the catalytic converters' impact on engine performances and etc. are discussed. The evaluation program for home-made catalytic converters, taking consideration of recommended test programs abroad and chinese situations, is first presented。
