| 中文摘要 |
| 建立了木薯乙醇-汽油混合燃料生命周期排放单目标和多目标优化模型.以生命周期CO,NOx,PM,HC,SOx,CO2排放为优化目标,对木薯乙醇-汽油混合燃料生命周期排放进行了单目标及多目标优化,并进行了灵敏度分析.结果表明:多目标优化后木薯乙醇-汽油混合燃料的混合比例为63%.与原始值相比,多目标优化后生命周期CO排放略有升高,NOx升高15%,PM升高19%;生命周期HC、SOx和CO2分别降低8%、50%和21%.

| 英文摘要 |
| An optimization model on life cycle pollutants emission of cassava based ethanol blended gasoline fuels, including single and multi objectives, was carried out in this paper. And, the single and multi objectives optimization of cassava based ethanol blended gasoline fuels were done, using the life cycle CO, NOx, PM, HC, SOx, CO2 emissions as objectives. Moreover, sensitivity analysis of design variables was done. The multi objectives results shown that the blend ratio between cassava based ethanol and gasoline was 63%.Compare with the initial value, multi objective optimization of cassava based ethanol blended gasoline fuels achieved a little more life cycle CO, NOx and PM emissions, about 1%, 15% and 19% respectively, and reduced life cycle HC, SOx and CO2 emissions, 8%, 50%, and 21% respectively. |
