摘要
F-T柴油是一种非常有潜力的清洁替代燃料。本文通过对1辆帕萨特柴油轿车燃用柴油/F-T柴油混合燃料时的气态排放物HC、CO、NOx和CO2进行实时测量,研究了新欧洲驾驶循环(NEDC)各工况下这些污染物的模态排放特性。试验结果表明:F-T柴油的模态排放特性曲线与柴油类似;在柴油中加入F-T柴油能够显著抑制柴油机在冷启动状态下的HC和CO排放,有效降低整个循环HC、CO、NOx和CO2的排放。
F-T diesel is quite a promising ultraclean alternative fuel. This study measured HC, CO, NOx and CO2 emissions from a Passat diesel car fueled with blends of F-T and conventional diesel fuels under different operating conditions of the New European Driving Cycle （NEDC） and investigated their modal characteristics. Test results show that modal emission characteristics of F-T diesel are similar to those of conventional diesel. The usage of F-T/conventional diesel blended fuels is an effective way to inhibit HC and CO emissions on cold start and to reduce the brake-specific emissions of HC, CO, NOx and CO2 simultaneously during the whole NEDC cycle.
