FIELD: manufacture of engines; fuel equipment for internal combustion diesel engines.
SUBSTANCE: proposed fuel-feed system includes high-pressure injection pump, fuel pipe line, injector with shut-off member, spring and movable member made in form of piston located in hydraulic chamber. Injector is provided with connecting passage for communicating the hydraulic chamber with fuel-feed passage of injector; fuel jet is located in fuel-feed passage. Gasket made from heat-, oil- and gasoline-resistant rubber is laid on lower cone of shut-off member. Sprayer orifices are made in form of taper convergent nozzles.
EFFECT: improved characteristics of fuel injection process; improved starting properties of diesel engine; increased power; enhanced economical and ecological parameters.
