Internal combustion engine fuel system with inverse model control of fuel supply pump

U.S. Patent Number: 5379741

Abstract: A feedforward control system for an electrically operated fuel injection pump for an internal combustion engine includes a controller for determining required fuel pressure and flow rate to be delivered by the pump and for using the determined fuel pressure and flow rate to determine a variable operating voltage for the pump. The variable operating voltage may be delivered as a pulsewidth modulated voltage, with the system being used to operate the pump in an open loop fashion.
