FIELD: mechanical engineering; fuel systems of internal combustion engines. SUBSTANCE: method comes to forming main flow of fuel-air mixture, generating hot steam using heat of engine exhaust gases with consumption of 0.2-0.4 of summary fuel consumption at rated duty, mixing steam by means of jet pump with fuel-air emulsion if idling system and delivering this mixture into main flow in form of separate cross stream at supersonic speed through gas-dynamic acoustic radiator with oscillation frequency of 18000-22000 Hz. Design peculiarity of supply system and CARBURETOR is provision of series-connected jet pump and gas-dynamic acoustic radiator connected to hot steam generation circuit with evaporation of idling system fuel using hot steam in jet pump. EFFECT: reduced toxicity of exhaust gases at any duties by creation of high-homogeneous fuel-air mixture with saturation of mixture with increased amount of water steam and finely divided water drops, increased economy and enhanced temperature conditions of engine. 5 cl, 43 dwg
