OPERATING METHOD OF INTERNAL COMBUSTION ENGINE, INTERNAL COMBUSTION ENGINE Russian patent published in 2020 - IPC F02B47/10 F02N15/02 F02N19/00 

FIELD: machine building.

SUBSTANCE: invention relates to the engine building. Method of internal combustion engine operation. In transient modes turbo-compressor rotor is additionally twisted by auxiliary electric machine (25). Electric machine is kinematically connected to turbo-compressor and receives power supply from storage battery (15) through auxiliary converter (26) of frequency and voltage. Steam supplied to turbine (7) at transient modes for turbocharger shaft swirling is obtained by heating water in heat exchanger (8) with exhaust gases of turbine compressor turbine and evaporation of water supplied to exhaust path of engine in front of turbine. As an additional gas mixture supplied to engine output in transient modes caused by load variation and during overloads, working mixture-air supplied to its inlet is used. Additional working body-heat carrier used for engine warm-up before start-up and at engine maintenance in hot reserve is prepared by means of combustion of fuel mixture and working mixture-air supplied from engine inlet pipeline at inlet before turbine. In heating modes supply of additional working body-compressed air into working mixture, as well as spinning of shaft of turbocompressor by electric machine is performed for period of its spin-up and beginning of operation on additional working body-heat carrier. In addition, recharging of accumulator battery is performed from thermoelectric generator (30), which is installed in place of water supply to engine outlet, as well as from auxiliary electrical machine kinematically connected to turbo-compressor. At low loads part of exhaust gases is directed to engine inlet, and water from exhaust gases is separated and discharged to heat exchanger. In all operating modes, electric power is supplied from electric machine directly to consumers. Internal combustion engine is disclosed.

EFFECT: technical result consists in improvement of efficiency of internal combustion engine, especially on fractional modes with partial load and idling, as well as in sharply alternating loads and overloads, expand its functional capabilities and scope of application.
