DEVICE FOR SUPPLY OF LIQUID FUEL TO DIESEL ENGINE INJECTORS

摘要

FIELD: engines and pumps.SUBSTANCE: invention can be used in internal combustion engines (ICE). Proposed device has fuel pressure amplifier 2, with spring-loaded stepped piston 10 inside. Fuel accumulator 3 comprises pipe installed in vice 4 consisting of a case with ear and yoke. Vice 4 are interconnected by threaded fasteners and fitted on casing 5 of pressure amplifier 2. Vice 4 are connected by threaded fasteners 6 with cylinder head 7 of the engine. Housing 5 of pressure amplifier 2 is made in the form of a sleeve with collar 8 inserted in engine cylinder head 7. On the housing of pressure amplifier 5 about the collar bushing 9 is fitted with a threaded connection with vice 4. Seal ring 26 is installed between clutch 4 and cylinder head 7 of the engine.EFFECT: reduced pressure loss of fuel fed into injector ICE, high pressure fuel injection in ICE cylinders to improve processes of mixture formation and combustion fuel without complicating the design.3 cl, 3 dwg
