LNG重型商用车和柴油重型商用车全生命周期环境排放差异评价
Evaluation of Difference between LNG and Diesel Heavy-duty Commercial Vehicle's Life Cycle Environmental Emission
摘要
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.关键词
