Abstract
A compressed gaseous fuel system for an internal combustion engine includes an electronic engine controller, a common fuel rail, fuel injectors operatively connected with the common-rail and with the engine controller, and a high pressure gaseous fuel source. A control regulator reduces gas system pressure to a final variable control pressure specified by the engine controller and furnishes the fuel at the control pressure to the common-rail. A fuel pump operatively connected with the control regulator and with the engine controller selectively transfers fuel from the fuel rail to a portion of the fuel system located upstream from the downstream pressure regulator in the event that the pressure within the common-rail exceeds a desired pressure.
