INTERNAL COMBUSTION ENGINE GASEOUS FUEL SUPPLY METHOD Russian patent published in 1997 - IPC

FIELD: mechanical engineering; internal combustion engines. SUBSTANCE: methods comes to forcing out gas under pressure from fuel cylinder along fuel pipe into suction duct through evaporator-heat exchanger with regulation of gas amount. Regulation of fuel amount is provided by adapted combination of multiple discrete fuel metering devices with preset accuracy of fuel delivery arranged in parallel on section of branched fuel pipe. Each separate discrete metering of amount of fuel is provided by electronic regulator depending of signals of speed transmitter and parameters of pressure and temperature in suction duct and metering device inlet pressure transmitter and temperature transmitter at device outlet. EFFECT: enlarged operating capabilities. 3 cl, 1 dwg
