SUPPLY SYSTEM FOR INTERNAL COMBUSTION ENGINE Russian patent published in 1996 - IPC

FIELD: engine engineering. SUBSTANCE: system has fuel pump 1 connected to nozzle 2 with space 5 and spraying openings 8 and additional fuel pump 9 with nozzle 11. Smaller space 12 is provided under needle 7 inside the housing of each nozzle 8 and 11. The space is in communication with water pump 16 through additional passageway 13 and pipe line. Rack 17 of the pump is coupled with rack 18 of fuel pump 1 and lever 19. Nozzles 8 and 11 are mounted at the edges of the cylinder cover. To reduce a load, lever 19 and racks 17 and 18 moves away to reduce water and fuel flow to nozzle 3 and nozzle 11 is in full operation. In so doing, the efficiency of the engine is maximum and the engine operates without overheating. When it is necessary to go to the partial loads (0.5P) lever 19 with racks 17 and 18 is set in intermediate position 25, the fuel pump 1 being shut off. Water pump 18 continues to supply a few amount of water to nozzles 3 and 11. The water prevents nozzles 3 to became clogged with cock without lifting needle 7. For further reduction in load, second fuel pump 9 is affected and nozzle 11 sprays fuel effectively as well. To stop the engine, lever 19 is set in position 26, water pump 16 is shut off and after a time delay fuel pump 9 is shut off. There is no water inside the cylinder in so doing. The engine is started in the reverse order. EFFECT: enhanced reliability. 2 cl, 3 dwg
