FIELD: mechanical engineering; internal combustion engines.
SUBSTANCE: invention relates to carbureted engines with spark ignition. According to invention, homogenized fuel mixture is formed by gauze homogenizer with provision of turbulent swirler. As a result, fuel mixture, mixing with remnants of exhaust gas into cylinder of internal combustion engine, forms homogenized working mixture, all fuel in which is in vapor and gaseous state. Angle of ignition determining delivery of spark for forced ignition of working mixture is within -5° -7° at TDC, and is within 0°±3° at idling and low loads.
EFFECT: provision of quick and practically complete combustion of fuel mixture which is favorable for operation of internal combustion engine.
