The article is devoted to the problems of increasing the energy efficiency of traction electric transmission of a shunting diesel locomotive. In the context of rising fuel costs, to maintain the competitiveness of rail transport, the issue of energy efficiency of the traction rolling stock, which accounts for about 90% of the total consumption of hydrocarbons by rail, is quite acute. At present, a number of measures have been investigated to improve the efficiency of diesel engines of locomotives, which allows getting an increase in the efficiency at the level of 1-5%.
internal combustion engine
The research of heat generation and heat consumption in a conventional or ideal engine provides useful information about the regularities, character of the process and effectiveness of fuel combustion in any real engine that cannot be subject to experiments. This information is advantageous both in case of heat transformation effectiveness analysis and the development of means to improve already employed engine.
