COMBUSTION CONTROL METHOD IN ICE WITH ELECTRIC TURBOCHARGER Russian patent published in 2020 - IPC F02B37/14 F02M26/05 F02M31/04 

FIELD: machine building.

SUBSTANCE: invention relates to engine building, particularly, to control methods of combustion of fuel-air mixture of gasoline internal combustion engines. Combustion control method in ICE (1) with electric turbocompressor (5) is characterized by the fact that in order to implement controlled homogeneous self-ignition in gasoline engine (1) pressure of supercharging air supplied to cylinders of engine (1) is controlled by electric turbocompressor (5). Temperature of air supplied to cylinders of engine (1) is also regulated by means of its heating due to heat energy of cooling liquid and exhaust gases, and also recirculated exhaust gases are added thereto from exhaust system. At that temperature of air supplied to cylinders of engine (1) is smoothly adjusted in wide temperature range by its heating additionally due to use of thermal energy of ICE lubrication system, as well as due to possibility of series, parallel or series-parallel connection of sections inside combined heat and power plant heat exchanger (10) depending on required temperature of heating of supercharging air, providing preset parameters of fuel-air mixture. High-temperature exhaust gases recycled from exhaust system and mixed with air are taken to mixer-homogeniser (6) to inlet of catalytic neutralizer (4) of exhaust gases.

EFFECT: technical result consists in reduction of fuel consumption at low and medium load modes, as well as reduction of harmful substances emissions.
