摘要：Diesel fuel savings during the operation of locomotive fleet is the most important question of the railway transport ofUkraine. Nowadays, the expenses for diesel fuel are one of the major expenses of locomotive industry of Ukrainian railways.Shunting diesel locomotives ChME3 operating on a two-unit system perform pulling the trains to the departure yard, maneuvering, idling, overtaking by a reserve, rearrangement of cars because of the difference in the height of automatic coupling and others. For each of these elements diesel-generator set operates in a specific mode.The main directions of improving the efficiency of electric power plants of shunting locomotives is reducing the idling time and time of transient processes.Many papers and technical solutions were dedicated to the issue of idle reduction. The main solution of reducing the idling time of diesel-generator set is to exclude one of the diesels from the operation.Disabling one diesel-generator set of shunting locomotives operating on the two-unit system is possible when maneuvering and idling. But frequent stops of diesels require the development of a new system of their start, since the current system can not provide frequent starts because of the lack of time to recharge batteries. Besides, frequent use of batteries boosts the requirements for their operating condition, which would increase the expenses for their maintenance, replacement and repair.
