Research of the Efficiency of Locomotive UzTE16M3 Operation and Tractive Qualities of the Rail Track Profile Marokand – Navoi Line of Uzbek Railway

The article presents the problem of substantiating the fuel and energy efficiency of the use of diesel-powered mainline locomotives on a real, hilly-mountainous section of the Uzbek railway. The problem is solved using the methods of the theory of locomotive traction for various conditions of organizing the operational activities of three-section mainline freight diesel locomotives UzTE16M3 when driving freight trains of different mass. The main research criteria are the kinematic parameters of the movement of freight trains and the parameters of the energy intensity of the investigated diesel locomotives of the UzTE16M3 series in the line under consideration. The given values of the total and specific consumption of natural diesel fuel for traction of trains in quantitative and monetary terms, the reduced travel time of the train in traction mode and the specific consumption of natural diesel fuel per trip are considered. The kinematic parameters and energy indicators of the transportation work of the investigated diesel locomotives on the hilly-mountainous section of the Marokand – Navoi of the Uzbek railway was established during the movement of freight trains without stops and with stops at separate points. The values of the traction quality criterion (properties) of the track profile for each section of the section under consideration were determined. The main indicators of the fuel and energy efficiency of operation of the investigated diesel locomotives in operation are obtained. The research results are recommended for instructor drivers and specialists of linear enterprises of the locomotive complex of the Uzbek Railways network for practical use.
