A numerical method is proposed for quantitative assessment of the specific effective air consumption and the influence of atmospheric air temperature on the working process of a diesel engine, taking into account various modes of its operation. The dynamics of changes in the values of the coefficients of excess air and filling the cylinder with a fresh air charge over the period of the diesel operating process is substantiated depending on the temperature of the outside and charge air, as well as the position of the locomotive driver’s controller, obtained in the form of tabular data and graphical dependencies. The possibilities of increasing the fuel efficiency of operating diesel engines up to 5 - 10 percent through quantitative and qualitative regulation of coolant temperatures or through throttling, heating and cooling of charge air are formulated. It is recommended to continue research to improve the quality of the operating process of supercharged transport diesel engines by substantiating the air characteristics of such diesel engines and their subsequent combination with diesel locomotive and fuel characteristics under partial load conditions and, especially, at low ambient temperatures.
