摘要

本研究通过"重型商用车燃料消耗量模拟计算系统V1.2"对不同车型的燃料消耗量进行模拟,采用差值对比、标准差分析、回归分析等方法,对比分析在CHTC与C—WTVC工况下的模拟值。研究表明:CHTC油耗模拟结果高于C—WTVC,其中CHTC的综合油耗模拟结果比C—WTVC高出17%,市区段模拟结果高出73%,公路段模拟结果高出15%,高速段模拟结果高出3.1%。市区段油耗差值的离散度最大,其次是高速段,再次是公路段,综合油耗差值离散度最小。
        This study calculates the fuel consumption of different vehicles by the "Fuel consumption simulation system of heavyduty commercial vehicle V1.2". Using differential comparison, standard deviation analysis, regression analysis, etc., to compare the different results of CHTC and C-WTVC. The main conclusions are as follows: the fuel consumptions of CHTC are higher than C-WTVC, the comprehensive fuel consumption of CHTC is 17% higher than C-WTVC, the fuel consumption of city cycle is 73% higher, the fuel consumption of highway cycle is 15% higher, and the fuel consumption of expressway cycle is 3.1% higher. The dispersion in urban cycle is the largest, followed by highway cycle and the expressway cycle, the dispersion of the comprehensive fuel consumption is smallest.
