燃用不同柴油替代燃料的柴油轿车经济性分析

Fuel Economy Analysis of Diesel Cars Based on Different Diesel Alternative Fuel

通过NEDC循环试验和道路试验,对柴油轿车燃用市售柴油(国Ⅱ柴油、沪Ⅳ柴油)、柴油与生物柴油混合燃料BD10和天然气合成燃料GTL进行试验,比较它们的燃油经济性。结果表明:在NEDC循环试验中,燃用BD10和GTL时的100km油耗比燃用市售柴油时分别升高3.06%和1.93%;在道路试验中,燃用BD10和GTL时的100km油耗比燃用市售柴油时分别升高2.23%和4.46%。

Both NEDC cycle test and road test are conducted on diesel cars fueled with commercial diesel fuels（National Ⅱ diesel fuel and Shanghai Ⅳ diesel fuel）,biodiesel BD10 and synthetic fuel GTL to compare their fuel economy.The results show that with NEDC cycle,the fuel consumption per 100 km of car fueled with BD10 and GTL are 3.06% and 1.93% more than that with commercial diesel fuels respectively;while in real-world driving,the fuel consumption with BD10 and GTL are 2.23% and 4.46% more than that with commercial diesel fuels respectively.
