摘要
机动车尾气是大气中一氧化碳(CO)、碳氢化合物(HC)、氮氧化物(NOx)和臭氧(O3)等空气污染物的主要来源,本文通过在采用不同发动机结构(电喷、化油器)的机动车进行尾气现状监测基础上,对所排放的CO、HC两种主要污染物采集的数据进行了深入系统研究,找出不同发动结构车型尾气排放特性,对控制机动车尾气污染,改善环境空气质量有重要的理论和现实意义。
Motor vehicle exhaust is the main source of air pollutants,such as carbon monoxide（CO）,hydrocarbon（HC）,nitrogen oxide（NOx）,ozone,and so on.Based on the exhaust situation monitoring of vehicles with different engine structures（EFI and carburetor）,this paper does a deep and systematical research of the collected data of the two main pollutants： CO and HC.The exhaust emission characteristics of vehicles with different engine structures are found,which is of theoretical and realistic significance for controlling vehicle exhaust and improving air quality.
