COMBUSTION CONTROL METHOD IN ICE WITH TURBO-COMPRESSOR Russian patent published in 2020 - IPC F02B37/12 F02B29/04 F02M26/05 F02M31/00 

FIELD: engines and pumps.

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 turbo-compressor (5) is characterized by that for implementation of controlled homogenous self-ignition in gasoline engine (1) pressure of supercharging air supplied to cylinders of engine (1) is controlled by turbo-compressor (5) with variable nozzle device turbines. Air temperature is regulated by heating thereof due to heat energy of cooling liquid and exhaust gases, and recirculated exhaust gases are mixed therefrom from outlet system. At that pressure of supercharging of air at modes of low and medium power is additionally regulated by supply of compressed air from receiver (30) to turbine of turbo-compressor (5) with variable nozzle device of turbine. Air temperature is smoothly controlled in a wide temperature range by heating it additionally by using heat energy of the ICE lubrication system (1), 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-homogenizer (6) to inlet of catalytic neutralizer (4) of exhaust gases.

EFFECT: reduced fuel consumption at low and medium load conditions, as well as reduced emissions of hazardous substances.
