Zusammenfassung: | According to one aspect of the present disclosure, a method of controlling a common rail fuel system of an engine system is provided. The common rail fuel system includes a fuel pump, a fuel rail, a plurality of fuel injectors, and a pressure-responsive relief valve fluidly coupled to the fuel rail. The method comprises identifying a pressure condition of the fuel rail indicative of the pressure-responsive relief valve being in an open and latched condition, the identification being based on detecting a rise and reduction in rail pressure within a threshold time period. The method further comprises terminating flow from the fuel pump, while the common rail fuel system is operating, to unlatch and close the pressure-responsive relief valve. |
