MIXTURE-TYPE DEVICE FOR GAS ENGINE AND GAS ENGINE Russian patent published in 2020 - IPC F02D19/02 F02D9/12 F02M21/02 F02M21/04 F02M26/17 F02M26/19 F02M26/51 F02M35/10 F02M9/127 F02M9/133 

FIELD: machine building.

SUBSTANCE: invention relates to a mixture-forming device for an internal combustion engine operating on combusted gas, as well as an internal combustion engine, in the suction path of which such a mixture-forming device is located. Mixing device (10) for arrangement in suction channel (3) of internal combustion engine (1) operating on combustible gas, including closing element (12), by means of which cross-section (14) of opening of suction channel (3) can be reduced internal combustion engine (1). At least one metering valve (16) for dosing of combusted gas into suction channel (3) of internal combustion engine (1), as well as at least one connector (18) for return supply of exhaust gas of internal combustion engine (1). Fresh air flow is transferred by redirecting geometry of closing element (12) into diffuser (22), wherein first place (24) for inlet of combusted gas and second place (26) for inlet of gas returned by return supply (5) of exhaust gas are located downstream of redirecting geometry.

EFFECT: technical result is improved mixture formation of gaseous fuel for internal combustion engine, reduced weight and size characteristics.
