INTERNAL COMBUSTION ENGINE FUEL SUPPLY DEVICE Russian patent published in 2001 - IPC

FIELD: mechanical engineering; fuel equipment of internal combustion engines. SUBSTANCE: invention is designed for delivery of liquid fuel in gaseous state into engine. Proposed device has fuel tank, electromagnetic shutoff valve, fuel-feed pump with constant-pressure valve, electronic device, electromagnetic valve, evaporator and mixer. Delivery of liquid fuel into engine is regulated by electromagnetic valve by signals from air flow rate turbine-transmitter installed in engine intake manifold which are amplified and converted by electronic device with subsequent vaporizing of fuel in evaporator and delivering of gaseous fuel into mixer. Electromagnetic valve can be installed after evaporator to regulate delivery of gaseous fuel into mixer. Delivery of gaseous fuel after evaporator can be provided by electromagnetic valve-nozzle by signals of crankshaft position pickup, amplified and converted by electronic, into the cylinder or intake channel near the cylinder in which intake stroke has started. EFFECT: reduced consumption of fuel and toxicity of exhaust gases owing to forming of fuel mixture at molecular level. 3 cl, 2 dwg
