摘要
通过发动机台架试验和道路运行,比较了城市客车使用天然气合成柴油(GTL)和普通柴油的能耗与排放;结合燃料生产阶段和运输过程的数据,分析和比较了两种燃料在城市客车上应用的全生命周期指标。结果表明,与柴油相比,在全生命周期内GTL的总能耗增加63%,石油消耗降低91%,排放有所恶化;而在车辆应用阶段,GTL在不同程度上改善了车辆的性能,其中以质量计的燃料经济性改善5%,VOC,NOx,CO,PM和SOx等排放均有大幅度的降低。
The energy consumption and emission of city bus fueled with gas-to-liquids （GTL） fuel and conventional diesel are compared through engine bench test and road driving. Combined with the data in fuel production and transportation phases, the life cycle indicator of two fuels used in city bus is analyzed and compared. The resuits show that, compared with conventional diesel, in the total life cycle, the total energy consumption of GTL increases by 63%, the petrol consumption reduces by 91%, and the emissions have certain deterioration; while in vehicle operation stage, GTL fuel improves all the vehicle performances in different degree. The fuel mass consumption decreases by 5%, and the emissions of VOC, NOx, CO, PM and SOx reduce by a big margin.
