Abstract:
A method of operating a dual fuel compression ignition engine includes controlling a liquid fuel pressure within the liquid fuel common rail toward a desired liquid fuel pressure, and controlling a gaseous fuel pressure within the gaseous fuel common rail toward a desired gaseous fuel pressure that is less than the desired liquid fuel pressure. The method also includes commanding a change in the liquid fuel pressure to a decreased liquid fuel pressure that is less than both the desired liquid fuel pressure and a current gaseous fuel pressure. The liquid fuel pressure is maintained above the gaseous fuel pressure during a transition of the liquid fuel pressure toward the decreased liquid fuel pressure by executing the pressure control algorithm.
