DEVICE FOR FEEDING LIQUID FUEL TO NOZZLES OF INTERNAL COMBUSTION ENGINE Russian patent published in 2016 - IPC F02M37/04 F02M57/00 F02M63/00 F02D41/28 

FIELD: engines and pumps.

SUBSTANCE: invention can be used in internal combustion engines (ICE). Proposed device has fuel pressure booster 1, in casing of which there is spring-loaded stepped piston 18. Fuel accumulator 2 comprises pipe installed in grip 3. Grip 3 consist of casing with lug and cover, jointed together by threaded fasteners. Vice are put on housing 4 pressure amplifier 1 and are connected by threaded fasteners 5 with ICE cylinder head 6. Pressure amplifier housing is made in form of case with collar 7 fitted in ICE cylinder head 6. On pressure amplifier housing 4 near collar bushing 8 is fitted with threaded connection with clutch 3, and furnished with seal ring 9 fitted in grip 3, between them and additional sleeve 10 with threaded connection with grip 3.

EFFECT: reduced pressure loss of fuel fed into ICE injector, high pressure fuel injection in ICE cylinders to improve processes of mixture formation and fuel combustion.
