摘要: Controlling a gaseous fuel internal combustion engine includes receiving a signal indicative of a desired state of an operating parameter of the engine dependent upon a fueling rate, and tracking the desired state via adjusting a pressure drop from a gaseous fuel common rail to an intake conduit such that the fueling rate is adjusted toward a fueling accordant with the desired state. The control further includes limiting an error in the tracking via executing the adjustment of the pressure drop responsive to a fluid pressure disturbance within the intake conduit.
