POWER SUPPLY METHOD OF PISTON INTERNAL COMBUSTION ENGINE AND AIR SUPPLY DEVICE FOR IMPLEMENTATION OF SAID METHOD Russian patent published in 2020 - IPC F02B29/06 F02B29/08 F02B33/44 

FIELD: aviation; engine building.

SUBSTANCE: group of inventions relates to piston two-stroke engines intended for aircrafts and other equipment operating in rarefied air. Essence of inventions consists in the fact that the engine supply method includes removal of exhaust gases with compressed air of high pressure before passage of the upper dead centre (UDC) piston, as well as formation of high pressure compressed air mixture, supplied after UDC. For this purpose, air supply device is used, which includes two-chamber receiver with chambers of different volume, with controlled inlet, for combustion chamber, valves and compressor with inlet and outlet valves. Small chamber (section) is intended for active purging of combustion chamber, and main chamber is intended for formation of working mixture. Volume of main section of receiver is at least equal to volume of combustion chamber. Inventions provide more complete removal of waste gases and maximum oxygen content in working mixture, higher power and efficiency, reduced toxicity of exhaust gases and maintenance of serviceability under conditions of rarefied air at high altitudes.

EFFECT: technical result is higher efficiency of cleaning cylinder.
