DIESEL ENGINE FUEL SYSTEM Russian patent published in 2015 - IPC F02M37/04 F02M57/00 F02M59/00 F02M63/00 F02D41/38 

Abstract RU 2554151 C1

FIELD: engines and pumps.

SUBSTANCE: invention proposes a fuel system containing fuel pump 28, a fuel pressure amplifier and injection nozzle 1. In housing 2 of the pressure amplifier there located is spring-loaded piston-multiplier 3, opposite which disk 11 separating drain valve 12 located after it is installed. A cavity between disk 11 and piston-multiplier 3 is interconnected with fuel accumulator 18 is interconnected with the fuel accumulator through a discharge valve and contains spring-loaded plunger made in the form of a pipe located in head of cylinders 5. Fuel pump 28 is interconnected with the fuel accumulator through a discharge valve and contains spring-loaded plunger 29 having a drive from cam shaft 26 of the engine. Plunger 29 is located in a sleeve installed in a cartridge enveloping a return spring of the plunger, which is arranged about the sleeve.

EFFECT: reduction of pressure losses of fuel supplied to the injection nozzle to increase spray pressure of fuel to engine cylinders to improve a process of mixture formation, and therefore, fuel combustion.
