摘　　要：海拔高度增加会导致空气密度减小,氧含量下降而使发动机的燃烧变差,污染物排放增加,整车油耗也会发生变化。因此有必要对不同海拔地区的汽油车排放及油耗情况进行研究,目前国内对相关领域的研究还处于空白。本文利用我中心海拔环境仓对两辆轻型汽油车进行各海拔高度环境下的排放及油耗试验,并对其在相应条件下排放污染物的排放量和油耗情况进行分析和比较,最终得出轻型汽油车的排放及油耗随海拔高度的变化规律。Increase in altitude will result in air density decrease,the poor combustion of engine and emit more pollutant,the fuel consumption will also change,so it is necessary to study the motor vehicle emissions and fuel comsumption in different altitude environment.Now the research of this field is in blank.In this paper,we perform emission test of two petrol cars in different altitudes using altitude climate chamber of CATARC,and analysis the variation of the pollutants and fuel consumption.We work out the principle of pollutant variation and fuel sonsumption in the different altitude environment at last.
