FIELD: mechanical engineering; internal combustion engines. SUBSTANCE: according to proposed supply method, gaseous fuel under gauge pressure is added to fuel-air mixture. Homogeneity of mixture is improved by converting gauge pressure of gaseous fuel into high frequency acoustic pressure which acts onto fuel mixture. Supply system has carburetor with through channel 1 with throttle valve, gas nozzle 3 installed in behind-the- throttle space 4, gaseous fuel supply circuit has acoustic radiator 7 whose output is connected to gas nozzle 3, and input is connected with pressure regulator 5. EFFECT: enlarged operating capabilities. 2 cl, 1 dwg
