FIELD: engine building.
SUBSTANCE: invention can be used in production and operation of internal combustion engines (ICE) of vehicles. According to the proposed method of controlling a two-stroke ICE, a fuel-air mixture (FAM) is homogenised in compressor cylinder (1) with an excess air coefficient of λ<0.5. After closing of blowing and outlet openings of working cylinder (4) fuel-air mixture in gaseous state is supplied to prechamber (21) and combustion chamber (23) at pressure in combustion chamber (23) higher than atmospheric pressure. Fuel-air mixture is depleted in combustion chamber (23) to excess air factor of 0.6<λ<2.0, using air supplied from working cylinder (4). After that, spark ignition of fuel-air mixture is performed. Fuel-air mixture is injected from compressor cylinder (1) into combustion chamber (23) at pressure 0.5–7 atm higher than that in working cylinder (4) at the moment of fuel-air mixture injection into combustion chamber.
EFFECT: invention makes it possible to increase stability of ICE operation due to operation without misfiring, which leads to increase in ICE efficiency.
