METHOD OF AND DEVICE FOR FUEL METERING, METHOD OF AND DEVICE FOR METERING OUT LIQUID MEDIA Russian patent published in 1998 - IPC

FIELD: mechanical engineering; internal combustion engines; fuel metering devices. SUBSTANCE: method of metering out fuel for delivering into engine comes to pressure feeding preset amount of liquid fuel into check chamber during each operating cycle. Check chamber directly communicates with injection chamber charged with compressed gas. Then amount of fuel required for cycle of operation, depending on load and (or) speed of engine, is set check chamber and metered out amount of fuel from check chamber is delivered into injection chamber charge with compressed air for subsequent delivery into engine combustion chamber. As usually required amount of fuel in check chamber is kept under pressure, excess amount of fuel is removed by opening takeoff valve. EFFECT: enlarged operating capabilities. 26 cl, 3 dwg
