Abstract:

The role of internal combustion engines (ICE) in efficient energy technologies is shown. Analysis of existing and industry-developed technologies for increasing the efficiency of using thermal emissions in internal combustion engines, including cogeneration, as well as the identification of promising areas that require further scientific research and justification is given. The components of the energy of exhaust gases obtained during the combustion of fuels and their thermodynamic components in the overall heat balance of the internal combustion engine are analyzed. The most well-known methods in technology for the recovery (use) of thermal energy of exhaust gases, their effectiveness depending on the operating modes of the internal combustion engine, as well as advantages and disadvantages are analyzed. The most preferable recycling systems are systems that do not require complicating design of the internal combustion engine itself, but are integrated as additional modules connected to the gas exhaust system of the internal combustion engine. New methods of using the energy of exhaust gases using a turbocompressor heat exchanger, as well as the possibility of using it in conjunction with a combination of known methods of heat recovery in an internal combustion engine are proposed.

Keywords: internal combustion engine, thermal energy, thermal balance, thermal emissions, heat recovery, turbocompressor heat exchanger.
