  • Variable geometry intake system for an internal combustion engine
    Patent number: 5740778
    Abstract: An intake system for a multicylinder internal combustion engine includes a manifold having inlet runners for conducting charge air into the cylinders of an engine, and at least one secondary throttle valve situated within at least one of the inlet runners. An electrically driven motor positions the secondary throttle valve, with the motor being operated by a controller, which senses engine operating parameters including the temperature of an electrically driven motor which powers the secondary throttle valve.

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