DEVICE FOR METERING CYCLIC FUEL FEED Russian patent published in 1998 - IPC

FIELD: fuel- feed equipment testing. SUBSTANCE: device is, essentially, injection chamber with drain valve communicating with metering chamber that accommodates moving plunger connected to metering sensor through solenoid coil tongue which moves it in response to varying voltage applied to it thereby building up back pressure within injection chamber opposing fuel injection which is equivalent to gas pressure within combustion chamber during fuel injection. Metering process is controlled by control system that has amplifier, analog-to-digital converter connected to computer, pulse sensor, and control unit actuating drain valve and solenoid coil. EFFECT: improved measurement accuracy and simplified design. 2 dwg
