FIELD: mechanical engineering; internal combustion engines. ^ SUBSTANCE: invention relates to fuel mixture preparation systems of internal combustion engines. Method to control fuel mixture composition in internal combustion engines includes increase of concentration of oxygen in gas mixture to optimum ratio with fuel by enriching atmospheric air getting into air clearance of internal combustion engine with oxygen. When changing over from idle running to maximum speed running, amount of fuel delivered into engine increased at change of amount of oxygen fed into gas mixture. Engines speed at reaching maximum value is limited by decreasing delivery of fuel by signal from engine speed sensor supplied into fuel amount control system. Control signal is formed to change amount of oxygen delivered into air cleaner. Device to control composition of fuel mixture in internal combustion engine with increase of concentration of oxygen in gas mixture contains fuel amount control system, engine speed sensor connected to fuel amount control system, air cleaner, oxygen bottom with valve and its control system. Valve is connected to air cleaner by pipe. Valve control system is connected with fuel feed sensor and is made for changing amount of oxygen delivered into air cleaner. Fuel amount control system is made for limiting delivery of fuel at maximum speed of internal combustion engine. ^ EFFECT: increased amount of oxygen with possibility of changing the amount depending on delivery of fuel and maximum tolerable speed of engine shaft and decreased consumption of fuel under other equal conditions. ^ 3 cl, 1 dwg |
