基于国内载货汽车燃油经济性现状，根据《JT 719—2008营运货车燃料消耗量限值及测量方法》中对燃油经济性定义和评定要求，进行轻型货车、重型货车和半挂车组的燃油经济性试验；对比不同吨位载货汽车的百公里油耗和百吨公里油耗的变化曲线，并进行相关性分析。结果表明：随着载货汽车质量的增加，货车的百公里油耗逐渐增大，但是百吨公里油耗却有逐渐减小的趋势，且不同类型车辆的百吨公里油耗分布在不同的数值区间内，体现了不同类型载货汽车的油耗特性。

Based on the current fuel economy situation of domestic trucks and according to the definition and evaluation requirements of fuel economy in “JT 719—2008 Limits and measurement methods of fuel consump-tion for commercial vehicle for cargos transportation”, fuel economy tests are conducted on light trucks, heavy trucks and tractor-semitrailer combinations, and the fuel consumption curves in both L/ 100km and L/ 100km·t of vehicles with different tonnages are compared and a correlation analysis is performed. The results indicate that with the increase of the total mass of trucks, their fuel consumption in L/ 100km increases, but the fuel consumption in L/ 100km·t shows a trend of reduction, and the fuel consumption in L/ 100km·t of different types of vehicles scat-tered in different value intervals, embodying the fuel consumption characteristics of different categories of trucks.
