SYSTEM TO MEASURE FUEL FEED AT BENCH FOR TESTING DIESEL ENGINE FUEL FEED COMPONENTS Russian patent published in 2010 - IPC G01M15/04 F02M65/00 

FIELD: engines and pumps.

SUBSTANCE: proposed system comprises unit of stand nozzles or adaptors to be connected to appropriate fuel feed sections of unit to be tested to feed work fluid (WF) via feed lines, driven device to feed WF in turn from every stand nozzle and adaptor via appropriate feed pipeline into measuring device, WF temperature pickup, tested unit drive shaft rpm pickup and control computer. Drive of distributing device and measuring device are connected to said control computer. Measuring device represents a vessel with its bottom communicated with electrically driven valve for draining the vessel, and WF column pressure pickup connected to electronic unit. Outlet ends of feed pipelines with dampers are arranged regularly along circumference. Distributing device represents an inclined intake pipe rigidly mounted on drive shaft. Lower end of said pipe is arranged directly above the vessel, while upper end is arranged to consecutively come under outlet end of appropriate feed pipeline during shaft turn. Electronic unit incorporates circuit to convert pressure pickup signal into WF feed magnitude.

EFFECT: higher accuracy of measurements, simplified design.
