FIELD: mechanical engineering; internal combustion engines. ^ SUBSTANCE: invention relates to designing and making of systems of air and fuel supply, exhaust gas conversion and discharge in vehicle engines. Invention is aimed at reduction of concentration of toxic matter in combustion products and improving efficiency of spark ignition engines. Proposed gas-air duct of engine contains intake system including air cleaner, throttling branch pipe with rotary gate to regulate total amount of air, air flow rate meter, individual intake pipelines combined by common receiver, additional throttles installed in intake pipelines, intake channels in cylinder head and exhaust valves, exhaust system including exhaust valves individuals pipelines, receiver, converter and muffler. Additional gates are made partially, turnable with individual drives operated by controller regulating composition of fuel-air mixture in each cylinder separately. ^ EFFECT: reduced toxicity and improved efficiency of multicylinder piston internal combustion engine with forced distributed fuel injection into intake pipeline of each cylinder. ^ 2 cl, 1 dwg |
