Abstract

Efficient use of diesel locomotives imply, in particular, high reliability in operation, minimum maintenance and repair costs, and maximum utilization of resource and energy potential. In this regard, a special role is assigned to technical diagnostics. The current reliability of a diesel locomotive at each given moment of its use depends on a number of factors acting in the period of time preceding this moment. For example, the reliability of a newly built locomotive depends on the level of research and development, the quality of manufacturing of assemblies and parts, as well as their assembly and adjustment. The reliability of a locomotive in operation is determined not only by the above factors, but also by the conditions in which it operates (climate, air dustiness, track layout and profile, weight of trains, etc.), as well as by the organization of its maintenance and repair (method of locomotive maintenance by crews, qualification of locomotive crews, frequency of inspections and repairs and volumes of repair work performed during these inspections and repairs, quality of repair work, etc.).
