铁路内燃机车所耗燃油费用在铁路运行费用中所占的比例愈来愈大,本文对货物列车运行中轨道马力的产生和利用进行了研究,分析了对燃油消耗有影响的参数,诸如:列车编组、车辆重量、坡度、平均速度、会车策略、手把位控制、机车车轴布置和列车编组。从数量上对燃油费用、货车重量减轻和所选择的列车编组做了估算。 The proportion of the fuel consumed by railway diesel locomotives in the running costs of the railway is increasing. This paper studies the generation and utilization of the orbital horsepower in the operation of freight trains, and analyzes the parameters that affect the fuel consumption, such as the train Grouping, vehicle weight, grade, average speed, meeting strategy, hand control, locomotive axle layout and train formation. Quantitatively estimates fueling costs, truck weight reduction, and selected train sets.
