The operational efficiency of diesel locomotives is largely determined by their reliability. The problem of ensuring the reliable operation of diesel locomotives has always been considered as one of the priority tasks for railway transport. Reliability management of diesel locomotives consists in establishing, ensuring and maintaining its level standardized by technical conditions at all stages of creating diesel locomotives and using them for their intended purpose. The effective use of diesel locomotives provides, in particular, their high reliability in operation, minimum maintenance and repair costs, maximum use of resource and energy potential. In this regard, a special role is given to the technical diagnosis of components and assemblies of a diesel locomotive. 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 the manufacture of components and parts, as well as their assembly and adjustment.
