摘　　要：对比分析了中国、美国、日本重型商用车燃料消耗量计算模型在车型分类、试验工况、评价单位和输入输出等方面的差异。选取典型重型商用车车型,基于发动机试验数据和整车参数,以中国、美国、日本燃料消耗量计算模型为工具,分别对各车型燃料消耗量进行模拟计算。通过比较车型燃料消耗量计算结果与中国、美国、日本现行燃料消耗量标准法规指标,评估我国重型商用车燃料消耗量和国际先进水平的差距,为确定2020年我国重型商用车整体节能目标和第三阶段燃料消耗量限值标准制定提供技术支撑和依据。This research compares and analyzes the vehicle classification,driving cycles,units,inputs and outputs of China,US and Japan’s simulation models,and selects typical heavy-duty commercial vehicle types.Based on engine test data and vehicle parameters,fuel consumption values were calculated under China,US and Japan’s simulation models.Compared with China,US and Japan’s relevant fuel consumption limits or targets,the gap of heavy-duty commercial vehicle fuel consumption between China and international advanced level was evaluated,which could provide technical support for the determination of China’s heavy-duty commercial vehicle energy-saving target in 2020.
