FIELD: engine building.
SUBSTANCE: invention can be used in fuel supply systems of internal combustion engines (ICE). Disclosed is a dual-mode fuel feed corrector in diesel ICE, comprising housing 1, in which by tightening diaphragm 2 between cover 3, shell 4 and housing 1 formed sealed cavity 5 of diaphragm 2 with nozzle 6 in shell 4 to supply pressure of supercharged air. Above diaphragm 2 disc 7 is rigidly connected with rod 9 installed with the possibility of movement along its axis relative to housing 1, at that, free end of rod 9 faces end of HPFP 11 rack and is arranged with the possibility of resting against end of HPFP 11 rack. Spring 8 is clamped between disc 7 and screw 10 made with possibility of adjusting force of tension of spring 8 due to displacement along thread in cover 3. Rod 9 is equipped with a cylindrical hollow rod 19 enveloping stock 9, and is installed with the possibility of movement along the axis of rod 19. Housing 1 is rigidly connected to rod outer surface 19. On external surface of rod 19 piston 13 is rigidly fixed. Rod 19 can move along its axis relative to base 16. In base 16 there is branch pipe 18 with the possibility of pressure supply into the tight over-piston cavity 14 along channel 17. Piston 13 is equipped with spring 15 and is installed with possibility of movement along its axis relative to base 16 at pressure supply into cavity 14 and return to initial position at pressure removal from branch pipe 18 due to force of preliminary tension of spring 15. Between housing 1 and base 16 there is adjusting washer 12, thickness of which is inversely proportional to stroke of piston 13, and base 16 is rigidly fixed on housing HPFP 22 on side of butt end of HPFP 11 rack.
EFFECT: technical result consists in improvement of operational efficiency and efficiency of ICE operation in diesel and gas-diesel operation modes with obtaining of high indicators of replacement of diesel fuel with gas.
