INTERNAL COMBUSTION ENGINE Russian patent published in 2020 - IPC F02B29/04 F02B31/00 F02M26/20 

FIELD: engine building.

SUBSTANCE: invention can be used in the internal combustion engines. Internal combustion engine includes cylinder (1) with piston, cover of cylinder with inlet and outlet channels, forming with piston and walls of cylinder combustion chamber, air intake (2) and ejector (5). Air intake (2) is installed at inlet to inlet channel (3). Passive nozzle (4) of ejector is connected to air intake (2) by means of pipeline (6) with check valve (7) arranged in it. In the cylinder wall there is radial hole (8) for partial exhaust of exhaust gases from the combustion chamber and tangential hole (9) for supply to the combustion chamber of a mixture of air and exhaust gases. Active nozzle (10) of ejector is connected with radial hole (8) in cylinder by means of pipeline (11) with check valve (12) installed in it and accumulating tank (13). Ejector diffuser (14) is connected to cylinder tangential hole (9). In the radial hole for partial exhaust of exhaust gases, petal valve (16) made of material having shape memory effect is installed.

EFFECT: technical result consists in improvement of reliability of start-up of internal combustion engine.
