2-8Wearing parts of the cylinder-piston group and crank mechanism is one of the main reasons for putting a diesel engine into repair. Timely detection of the occurrence of intense wear allows you to prevent negative consequences, make timely repairs, eliminate the likelihood of unplanned exit of the locomotive from service. As a result of the study of the intensity of accumulation of wear products in engine oil, a mathematical model has been developed, which is implemented with the use of an artificial neural network apparatus. Its use allows to carry out an operational assessment of the technical condition of diesel engine parts in an in dividing way and to improve the technological process of repairing diesel engines of the D49 type -

17-25On the basis of a previously proposed General method of using a database of measurements onboard system parameters diesel generator set of shunting locomotives a technique of determining the distribution law of the values characterizing the intensity of change of current of the traction generator, evaluation parameters, determining a model function of the parameter changes on the overhaul period. The technique and criteria for assessing the technical condition of the diesel generator set of the observed locomotive using the model function are given -
