FIELD: engines and pumps.
SUBSTANCE: invention can be used in internal combustion engines. The method of control of pressure of the fuel guide distributor (3) of the fuel system is offered which contains the fuel pump (1), at least, one injector (4) and the fuel guide distributor (3), connecting the injector (4) with the pump (1) containing the following stages: - establishing the relation ratio between the pressure of the fuel guide distributor (3) and efficiency (η) of the pump (1), - estimate of speed of fuel removal from the fuel guide distributor (3) for fuel on the basis of, at least, speed (Qinj) of fuel injection, - estimates of desirable speed of the pump (1) supply on the basis of the speed of fuel removal and efficiency (η) and - the pump (1) control for work with desirable speed of input flow. The controller for implementation of the method and the machine-readable data media are also offered.
EFFECT: maintaining of necessary pressure of fuel supply to nozzles providing optimum characteristics of fuel injection under various operating conditions.
