DEVICE FOR CONTROLLING ADVANCE ANGLE OF FUEL INJECTION IN DIESEL WITH SUPERCHARGING Russian patent published in 1995 - IPC

FIELD: engine engineering. SUBSTANCE: device has servo motor 1 whose piston 2 is coupled with controlled clutch 6. The clutch connects the shaft of the fuel pump with the driving shaft. Feeding pump 31 is connected with inlet passageway 12 of speed meter through passageway 33. The speed meter is provided with weight-slide-valve 10 whose outlet passageway 13 is connected with servo motor 1 through double-edge slide valve 18 or with discharging passageway 19. Double-arm slide valve 18 is coupled with rod 20 of air-operated corrector 21 which, in turn, is in communication with air delivery pipe line of the Diesel. The device controls the advance angle of fuel injection depending on the supercharging pressure and speed of rotation of the shaft of the high pressure fuel pump. EFFECT: enhanced reliability. 1 dwg
