FIELD: engines.
SUBSTANCE: invention relates to engine building, in particular, to two-stroke internal combustion engines (ICE). Disclosed is a two-stroke ICE comprising a cylinder with a combustion chamber, a piston, ignition plug 3, fuel injector 2, air injector 1 and an outlet valve with electric drive 4 and pneumatic drive 5, which are installed in the cylinder head of the ICE and electrically connected to the engine control unit. Engine crankcase is connected to air nozzle 1 and exhaust valve pneumatic drive 5 by means of receiver tube 7, on which bypass valve 6 and electrically controlled bypass valve 8 are installed, which control air pressure in receiver tube 7. Electrically controlled bypass valve 8 is electrically connected to engine control unit. Air filter 10 with valve 13 is installed on the crankcase. To increase the air compression pressure in the ICE crankcase, the lower part of the piston has outlets on the piston, which fill the space between the crankshaft cheeks at the lower dead point.
EFFECT: increased efficiency and improved performance of ICE.
