| 摘 要： | 基于生命周期评价理论建立了液化天然气(liquified natural gas, LNG)重型商用车与柴油重型商用车的生命周期环境排放差异评价模型。通过实证分析,LNG搅拌车和柴油搅拌车相比,NOx排放量减少了32.83%,SOx排放量减少了83.68%,PM排放量减少了100%;而CO排放量却增加了21.39%,HC排放量增加了7.83倍。在CO2排放方面,使用阶段LNG搅拌车的排放量比柴油搅拌车减少了6.82%,全生命周期LNG搅拌车的排放量比柴油搅拌车减少了8.88%。

| Abstract: | An evaluation model of the difference between LNG and diesel heavy-duty commercial vehicles' life cycle emissions was established. Through an empirical analysis of the LNG and the diesel heavy-duty commercial vehicle, it is found that the NOx, SOx and PM of the LNG vehicle are reduced by 32.83%, 83.68% and 100% relatively comparing to the diesel vehicle, but CO emission is increased by 21.39%, the HC emission increases 7.83 times.Meanwhile, the LNG heavy-duty commercial vehicles' CO2 emission in the using phase is 6.82% less than that of the diesel vehicle, but 8.88% more in the whole life cycle. |
