Individual Drive of Internal Combustion Engine Lubrication System Based on Switched Reluctance Motor

The article analyses the modern lubrication systems for internal combustion engines. Systems with mechanical drive components that contain mechanical and electronic components have been found to have a number of disadvantages. In particular, when the internal combustion engine is started cold, when the viscosity of the oil is high, the hydrodynamic resistance characteristic rises sharply, which leads to high pressure at low speeds and the drive requires low pump speeds.

Analysis of ways of increasing the energy efficiency of traction electric transmission of shunting diesel locomotive

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%.

Heat generation and heat consumption in engine of rapid internal combustion

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.
