ENERGY PLANT FOR RECOVERY OF THERMAL ENERGY OF EXHAUST GASES OF INTERNAL COMBUSTION ENGINES Russian patent published in 2021 - IPC F02G5/04 

FIELD: internal combustion.

SUBSTANCE: invention can be used in internal combustion engines. The power plant for utilizing the thermal energy of the exhaust gases of internal combustion engines contains a turbine (7), a liquid-jet ejector (6) of a turbine, a condensate pump (5), a condenser (9), an electric generator (8), a pressure reducing valve (12) and an engine coolant circulation circuit (1) internal combustion. The liquid inlet of the liquid-jet ejector (6) is connected to the outlet of the high-pressure condensate pump (5) installed after the condenser (9). An electric generator (8) is installed on the same shaft with a turbine (7), the outlet of which is connected to the inlet of a condenser (9) cooled by a fan (10). The coolant circuit of the internal combustion engine (1) includes a cooling jacket (2) and a circulation pump (3). There is a recuperative heat exchanger (4) installed in the cooling jacket (2) in such a way that the inlet to its heating part is connected to the outlet of the cooling jacket (2), and the outlet from the heating part through the circulation pump (3) is connected to the jacket inlet (2) cooling. The inlet through the heated part is connected to the outlet of the high-pressure condensate pump (5), and the outlet through the heated part is connected to the liquid inlet of the liquid-jet ejector (6) of the turbine. The gas inlet of the liquid-jet ejector (6) of the turbine is connected to the outlet of the exhaust gases from the internal combustion engine (1), and the outlet is connected to the inlet of the turbine (7). The inlet of the condenser is connected to the inlet of the vapor of the liquid-jet condenser ejector. The condensate inlet of the condenser (9) is connected via a pressure reducing valve (12) to the outlet of the high-pressure condensate pump (5). The outlet of the liquid-jet ejector (11) of the condenser is connected to the inlet of the separator (13). The gas outlet of the separator (13) is connected through a pipe (14) to the atmosphere, and the liquid outlet is connected to the inlet of the high-pressure condensate pump (5).

EFFECT: technical result consists in increasing the use of the heat of the exhaust gases of the engine.
