摘要
针对汽车尾气污染物排放浓度与过量空气系数 (α)的关系 ,通过对实际车辆的测试进行了比较 ,说明α在0 .85～ 1 .0 5时 ,汽车运转时不但可达到最佳的动力性、经济性 ,还可降低尾气排放浓度 。
According to the relation between concentration of pollutant from automobile tail gas and the excessive air coefficient,it shows that automobiles can not only achieve to the best power,economy but also decrease pollutant concentration and air pollution when the α value ia between 0.85 and 1.05.
