DISTRIBUTED INJECTION DEVICE FOR INTERNAL COMBUSTION ENGINES Russian patent published in 2003 - IPC

FIELD: mechanical engineering; fuel equipment of internal combustion engines. SUBSTANCE: proposed device for distributed injection contains air mass flow rate detector, intake manifold with receiver and throttle valve, fuel nozzles and electronic control unit. Intake manifold is provided with branch pipe which has equal in number to number of engine cylinders at one end, and additional gate at other end. Additional gate and throttle valve are coupled by axle of rotation. Taps of branch pipe are arranged on exhaust manifold for heating. Ends of taps are fitted in standard places of fuel nozzles which are installed on branch pipe at the beginning of ramification. Nozzle mounting places are provided with heat-insulating inserts. EFFECT: provision of homogeneous fuel mixture, increased efficiency of engine. 2 dwg
