HYBRID THERMAL ENGINE Russian patent published in 2019 - IPC F02G5/04 F01B21/04 F02B73/00 

FIELD: engine building.

SUBSTANCE: invention relates to the field of engine building and represents a hybrid plant with utilization of heat of the internal combustion engine. Essence of the invention consists in that the installation includes an internal combustion engine 1 with exhaust path 2, having a cooling liquid circulation circuit, in which cooling jacket 3 with liquid pump 4 is connected, and low-boiling working fluid circulation circuit with pressure and drain lines 5 and 6. Latter comprises tank 7 with working fluid, heat exchanger where low-boiling working liquid is heated for cooling liquid and exhaust gases, as well as low-boiling operating fluid vapor pressure energy converter and valve system 9–12. Engine is equipped with cooler-radiator 13 and expansion tank 14 installed in low-boiling working fluid circulation circuit, energy converter is made in the form of rotary-steam engine, and heat exchange device is in form of two heaters 15 and 16 installed in pressure main line 5. Heater 15 is connected to coolant circulation circuit and is connected through check valve 9 to fluid chamber 17 of container 7 and other heater 16, which is connected to outlet channel 2 and connected through boost valve 11 to expansion tank 14 and to input of energy converter 8 in form of rotary steam engine, which output is connected in series with cooler-radiator 13, and through support valve 12 – with tank 7. At that, the rotary steam engine by its output shaft is mechanically connected to the output shaft of the internal combustion engine 1. When the engine is in operation, heaters 15 and 16 overheat the low-boiling working liquid, which turns into steam, drives energy converter 8 in the form of a rotor-steam motor, which then transmits power to the output shaft of the internal combustion engine 1 via a mechanical link. Low-boiling working liquid after cooler-radiator 13 is condensed and supplied to vessel 7.

EFFECT: higher efficiency due to use of heat energy of cooling system and exhaust gases with conversion of this energy into additional mechanical energy of drive.
