摘要
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 consumption 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 ·of different types of vehicles scattered in different value intervals, embodying the fuel consumption characteristics of different categories of trucks.
