摘　　要：为了准确计算客车的燃油消耗量,本文在分析公路客车油耗影响因素的基础上,研究了油耗对于整备质量和载质量的敏感度以及速度修正系数的分析、计算方法;运用燃油消耗平衡原理,建立了基本运行条件下客车燃油消耗量的计算模型,分析了不同整备质量、载质量和速度下的计算误差。该模型考虑了气温和气压的影响,克服了原标准模型测量参数较多的弊端,比以往的油耗模型更为科学和简便。For calculating fuel consumption of passenger vehicle accurately,based on the analysis of main influencing factors of passenger vehicle fuel consumption,the calculation methods of fuel consumption＇s sensitivity to curb weight and passenger weight were discussed,and the calculation method of correction coefficient of speed was given.By applying equilibrium theory of fuel consumption,the calculation model of fuel consumption about passenger vehicles under the basic driving conditions was built,and the calculation errors in different curb weights and speeds were analyzed accordingly.The presented model could consider the influence of air temperature and air pressure on fuel consumption,and get out of the disadvantage of the standard model that there are too much measurement parameters.It is more scientific and convenient than previous models of fuel consumption.
