摘　　要：基于7辆国6轻型车的WLTC循环测试,计算了汽油、E10和MTBE10(汽油中添加10%体积的甲基叔丁基醚)排放的温室气体的致暖效应(GWP)、臭氧生成潜势(OFP)和非甲烷有机气体(NMOG)排放.结果表明,车队平均N;O和CH;排放的GWP分别为0.6和0.07gCO_(2)e/km.E10和MTBE10的非CO;温室气体排放的GWP比汽油更高.从整个碳生命周期看,生物质E10可以使温室气体排放的GWP下降5%~15%.E10和MTBE10都倾向于增加苯系物(BHC)排放和OFP.试验车辆的NMOG排放在30mg/km左右,使用含氧燃料E10和MTBE10没有显示出大幅度增加NMOG的现象.Based on the WLTC test results of seven China-6 compliant light-duty vehicles, the global warming potential(GWP),ozone formation potential(OFP), and non-methane organic gases(NMOG) with gasoline, E10, and MTBE10 were calculated and discussed. The GWP of crew-averaged N;O and CH;emissions were respectively 0.6 and 0.07g CO;e/km. The GWP of non-CO;greenhouse gases with E10 and MTBE10 fuelling was higher than those of gasoline. Bio-E10 is capable of removing 5%~15% of life-cycle GWP from gasoline vehicles. E10 and MTBE10 both tended to increase benzene hydrocarbon(BHC) emissions and therefore OFP. The NMOG from the test vehicles was roughly 30mg/km. The employment of oxygenated fuels, such as E10 and MTBE10, didn’t result in an obvious increase in NMOG.
