Abstract

A need to determine the performance efficiency of diesel locomotives arises when it is necessary to assess the quality of work done by operating organizations and make a comparative assessment of the adoption of new locomotives, new structural parts of their power plants, or new control algorithms. The first of these tasks is accomplished using the data obtained during the operation of locomotives, the scope of tkm work performed, the aggregate diesel fuel consumption, the quality of following the train schedule, and other indicators. To comparatively assess the efficiency of using locomotives of different series or adopting structural modifications, it is necessary to derive corresponding criteria of assessment and mathematical tools that will allow taking into account the peculiarities of power plants installed on locomotives. This article considers existing approaches to assessing locomotives on the basis of energy efficiency and proposes a new integrated vehicle energy efficiency index, a technique for calculating this index, a technique for representing train operations in a limited set of single train running modes, and a procedure for designing these modes considering stationary and unsteady operational modes of the power plant and equipment assemblies.

机车的能源效率

摘要

当需要评估运营组织的工作质量并比较采用新机车，其电厂的新结构部件或新控制算法时，就需要确定柴油机车的性能效率。这些任务中的第一个任务是使用机车运行期间获得的数据，完成的tkm工作范围，柴油总燃料消耗，遵循火车时刻表的质量以及其他指标来完成的。为了比较地评估使用不同系列的机车或采用结构修改的效率，有必要导出相应的评估标准和数学工具，以考虑安装在机车上的电厂的特殊性。
