为确定道路运输车辆实载率的提升对车辆油耗的影响情况,从道路运输车辆实载率和单耗的定义出发,通过数学理论计算,燃油消耗率特性分析等方法,确定了车辆实载率和单耗的变化存在倒数关系。进一步以除实载率外其他油耗影响因素均相同的六工况循环实际道路试验所得数据为基础,利用回归分析和曲线拟合,得出了不同车型车辆实载率和单耗之间的关系模型,并利用残差分析对模型进行验证。最终证明实载率的提高会造成车辆单耗下降,随着基础实载率的提高,提高相同比例,单耗的降低呈下降趋势。
In order to determine the influence of the actual loading rate of road transport vehicles on the vehicle fuel consumption, starting from the definition of actual load and unit consumption of road transport vehicles, through the mathematical theory calculation and fuel consumption rate analysis, There is reciprocal relationship with the change of unit consumption. Based on the data obtained from the actual road test of six-working cycle with the same factors except fuel consumption, regression analysis and curve fitting were used to find the relationship between the actual vehicle carrying rate and the unit consumption Model, and use residual analysis to verify the model. Finally, it is proved that the increase of the real load ratio will cause the unit consumption of the vehicle to decrease. With the increase of the basic real load ratio, the decrease of unit consumption will decrease when the same proportion is increased.
