- It is offered to dose out a cyclic portion of fuel by change ofduration of the first period of feeding that is reached by regulation of the moment of landing of the delivery valve. The mathematical model of fuel feed system with the steered delivery valve is developed. Numerical and experimental methods defined cyclic fuel delivery at change of the moment of closing of the delivery valve. Within the limits of studying of the feeder of fuel in skilled system, redistribution of a cyclic portion of fuel between the periods of a cycle and quantity of the fuel compressed in separate cavities of a delivery high-pressure pipe was defined. The important feature of the feeder - earlier landing of the delivery valve, than nozzle valve closing is found out. It absence of repeated lifting of a nozzle valve ("secondary injections") speaks all investigated high-speed and loading modes. The offered method of dosing out of fuel feed allows eliminating an essential lack of a traditional fuel system where feeding and dosing out processes are combined. The paper explains the absence of the repeated rise of the injector needle at all calculated regimes. A wave of pressure generated at setting the valve comes to the injector before the fuel feed is over. This excludes additional fuel injections even at high initial pressure in the force main in principle.
