大型客车柴油燃料生命周期分析

以实施第1及第2阶段限值后的大型客车为对象,对车用燃油从原油开采、运输、炼油WTT(Well-to-Tank)到车辆使用TTW(Tank-to-Wheel)等多个环节,即燃料生命周期WTW(Well-to-Wheel)内的能量消耗和温室气体排放进行了定量分析,WTT阶段的分析使用了有关统计数据,TTW阶段的分析采用了试验数据.结果表明:WTW阶段的能量消耗和温室气体分别是TTW阶段的1.151倍和1.153倍;WTT阶段各环节的能量消耗占总能量消耗的比例分别为6.7%,0.42%,6.1%,温室气体排放占总排放的比例分别为1.92%,1.42%,9.97%;大型客车第1阶段燃料消耗量限值的实施可降低12%的能量消耗和11.8%的温室气体排放;第2阶段燃料消耗量限值的实施可降低16.93%的能量消耗和17.67%的温室气体排放.

Well-to-wheels analysis of large-scale bus diesel fuels

Well-to-wheel assessment was used to evaluate the energy utilization and greenhouse gas emissions from crude oil extraction,transport,refining,namely well-to-tank(WTT),to vehicle operation,tank-to-wheel(TTW) for large-scale bus conformed to first and second phase of the fuel consumption limits.Statistical data was analyzed in WTT,test data was analyzed in TTW.Results shows that the energy consumption and greenhouse gas emissions in WTW were respectively 1.151 and 1.153 times that in TTW.Energy consumption p...
