摘要
CO2减排是社会关注的焦点,而汽车已经成为CO2排放的重要来源,加强节能环保、减少CO2排放量、抑制温室效应已经受到高度重视。通过方差分析,得出排量、里程、参考车重、油耗,HC、NOx、CO这7个因素对CO2排放量的影响是显著的。通过主成分分析方法分析这些因素对CO2排放量的影响程度,发现这7个因素中,按照影响程度大小排列依次是参考车重、排气量、里程、油耗、NOx排放量、CO排放量、HC排放量。车辆自有参数对CO2排放量的影响较大,而其他排放污染物对CO2排放量的影响相对较小。
The reduction of CO2 emissions is a major policy concern of the international community, and vehicles have become an important source of CO2 emissions. Energy economy and environmental protection, greenhouse effect control and CO2 emissions reduction have become a concern of union. In this paper, it＇s revealed that CO2 emissions was affected by displacement, mileage, vehicle weight, fuel consumption, hydrocarbon emissions （HC）, nitrogen oxides emissions （NOx） and carbon monoxide emissions （CO）. The order was vehicle weight, displacement, mileage, fuel consumption, NOx emissions, CO emissions and HC emissions, according to extent of effect. The effect of vehicle specifications was more than other emissions.
