  • Control method of an electronic injection fuel feeding system
    Patent number: 7942133
    Abstract: A control method of an electronic injection fuel feeding system for an internal combustion engine and displaying at least one injector and a non-continuous flow rate fuel pump actuated by a an actuator device; the control method includes the steps of: determining the desired fuel amount which must be injected at each cycle of the internal combustion engine; driving the injector for injecting the desired fuel amount at each cycle of the internal combustion engine; determining an optimal pumping frequency of the actuator device of the fuel pump according to the desired fuel amount which must be injected at each cycle of the internal combustion engine; and actuating the actuator device of the fuel pump at the optimal pumping frequency.
