| 摘 要： | 比较了客车燃用两种不同比例二甲醚—柴油混合燃料及普通柴油的能耗与排放。结合燃料生产阶段和运输过程的数据,分析和比较了不同燃料在客车上应用的全生命周期指标。结果表明,与柴油车相比,在全生命周期内二甲醚—柴油混合燃料车的VOC,CO,NOx和PM的排放分别降低,且随着混合燃料中二甲醚比例的增加,有害排放物下降得更多,但混合燃料车的总能耗、CO2和SO2排放分别增加。

| Abstract: | The energy consumption and emission of city bus fueled with two kinds of different proportions of DME/diesel blends and conventional diesel are compared through engine bench test and road driving.Combined with the data in fuel production and transportation phases,the life cycle indicator of different fuels used in the city bus is analyzed and compared.The results show that,compared with conventional diesel vehicle,in the total life cycle,and the VOC,CO,NOx and PM emissions decrease and these emissions decre... |
