FIELD: mechanical engineering; internal combustion system.
SUBSTANCE: according to proposed method of silencing exhaust noises of internal combustion engine provided with intake system with throttle valve, exhaust gas fluctuations are reduced by delivering air into gas-air duct after throttle valve, air being fed as into intake system of engine after throttle valve at its closing. Intake system of internal combustion engine has air cleaner, carburetor, throttle valve, intake manifold, control device and valve communicating intake manifold, after throttle valve at sharp closing of throttle valve, with source of additional air. Electromagnetic valve is used for this purpose, and control device is made in form of control unit of override-duty economizer.
EFFECT: increased efficiency of noise silencing owing to prevention of back flows in exhaust system.
