FIELD: mechanical engineering; internal combustion engines.
SUBSTANCE: invention relates to fuel systems of internal combustion engines. Proposed fuel system contains carburetor with throttle valve, gas nozzle installed in behind-the throttle space of flow-through channel, gaseous fuel feed circuit including series-communicating pressure reducer and gas bottle and acoustic radiator. Electromagnetic valve installed at pressure reduced outlet is connected by pipeline with acoustic radiator and with drive of throttle valve opening depending on angle of turning.
EFFECT: increased economy, improved characteristics of engine under conditions close to maximum power.
