FIELD: internal combustion engines.
SUBSTANCE: invention can be used in diesel fuel feed systems of internal combustion engines (ICE). Disclosed is a diesel fuel supply system comprising a distribution type plunger fuel pump of distribution type 4, hydraulically actuated injectors 8 of diesel cylinders, electric valve 7 installed in injection cavity of fuel pump with possibility of end of fuel supply to appropriate nozzle of diesel cylinder, electronic control unit 11 connected to diesel sensors, electric valve 7 and step motor 6. High-pressure plunger fuel pump 4 is kinematically connected and synchronized with diesel engine cranked or distributing shaft via spline coupling 5, having at least on one side screw splines and controlled by step electric motor 6 from electronic control unit 11. Drain and suction channels of high-pressure fuel pump 4 are combined.
EFFECT: invention allows improving reliability, reducing prime cost of the system, reducing toxicity, noise emission, improving economy and intake capacity of the engine.
