| 中文摘要 |
| 依据GB 18352.3-2005Ⅰ 型试验循环,对帕萨特柴油轿车燃用沪四柴油、煤基F-T合成油、体积混合比例分别为10%和50%的煤基F-T合成油-沪四柴油混合燃料的CO、NOx、HC、PM和CO2排放特性进行了试验研究,分析了该车燃用F-T合成油尾气污染物排放的环境影响特性. 结果表明,GB 18352.3-2005 Ⅰ 型试验循环中,该车燃用煤基F-T合成油-沪四柴油混合燃料城区行驶循环排放的CO、HC、PM和CO2相对较高,城郊行驶循环排放的NOx相对较高; 与沪四柴油比较,该柴油轿车燃用煤基F-T合成油-沪四柴油混合燃料后,其CO、NOx、HC、PM和CO2排放均有不同程度的降低,且产生气溶胶、酸化、全球变暖等环境影响的潜力减小. 煤基F-T合成油是一种较理想的柴油替代/补充燃料. |
| 英文摘要 |
| According to the first type test cycle of China national standard GB 18352.3-2005, the CO, NOx, HC, PM and CO2 emission characteristics of a PASSAT diesel car fueled with Shanghai local Ⅳ diesel, coal based Fischer-Tropsch (F-T) diesel, and the blends of coal based F-T diesel and Shanghai local Ⅳ diesel up to 10% and 50% by volume were analyzed respectively. And the environmental impacts such as decreased air quality, health impact, photochemical ozone, global warming, and acidification that could be caused by CO, NOx, HC, PM and CO2 emission of the diesel car were also assessed. The results showed that under GB 18352.3-2005 No. 1 test driving cycle, which consisted of four urban driving cycles and one extra urban driving cycle, the CO, HC, PM and CO2 emissions were released mainly in the urban driving cycles whereas the NOx emissions occurred mainly in the extra urban driving cycle. Compared with Shanghai local Ⅳ diesel, all of the CO, NOx, HC, PM and CO2 emissions of the diesel car decreased to different extents when fueled with coal based F-T diesel blends. Moreover, the aerosol generation potential, global warming potential and acidification potential of F-T diesel fueled diesel car were also reduced. To sum up, coal based F-T diesel would be one of the alternative fuels to diesel in China. |
