Claims
- 1. A method for controlling an engine, comprising:transferring electrical energy generated in a stator winding of a first plural phasor motor driving a cylinder valve during closing of said first cylinder valve to a stator winding of a second plural phasor motor driving a second cylinder valve to open said second cylinder valve.
- 2. The method of claim 1 wherein said transferring step includes:generating a current in said stator winding of the first plural phasor motor while de-accelerating said first cylinder valve towards a closed position; and, routing said current to stator winding of the second plural phasor motor to induce said second cylinder valve to move towards an open position.
- 3. The method of claim 1 wherein said first and second cylinder valves communicate with first and second engine cylinders, respectively.
- 4. A method for controlling an engine, comprising:transferring electrical energy generated in a stator winding of a first plural phasor motor, such motor having the rotor thereof coupled to a first cylinder valve, to a stator winding of a second plural phasor motor, such second plural phasor motor having a rotor thereof coupled to a second cylinder valve, such electrical energy being used by the first plural phasor motor prior to the transfer during closing of said first cylinder valve, such transferred energy being used by the second plural phase motor to open said second cylinder valve.
- 5. A method for controlling an engine, comprising;transferring electrical energy generated in a winding of a first plural phasor motor during closing of a first cylinder intake valve driven by the first plural phasor motor to a winding of a second plural phasor motor to open a second intake valve driven by the second plural phasor motor.
- 6. A method for controlling an engine, comprisingrecirculating a current generated in a winding of a first plural phasor motor used to drive a cylinder exhaust valve while de-accelerating said cylinder exhaust valve towards a closed position to a winding of a second plural phasor motor used to drive a cylinder intake valve to open said cylinder intake valve.
- 7. A method for controlling an engine comprising:recirculating a current generated in a winding of a first motor of a plural phasor motor driving a first exhaust valve while de-accelerating said first exhaust valve towards a closed position to a winding of a second plural phasor motor driving a second cylinder exhaust valve to open said second cylinder exhaust valve.
- 8. A method for controlling an engine, comprising:recirculating a current generated in a winding of a first plural phasor motor driving a first cylinder intake valve while de-accelerating said cylinder valve towards a closed position to winding of a second plural phase motor driving a second cylinder intake valve to open said second cylinder intake valve.
- 9. A method for controlling an engine comprising;reversing a flow of current in a winding of a plural phasor motor communicating with a first engine cylinder valve when said first valve is being closed; and, directing said current to a winding of a second plural phasor motor communicating with a second engine cylinder to induce said second valve to move towards an open position.
- 10. The method of claim 9 wherein said step of reversing said flow of current occurs when said first valve is being de-accelerated towards a closed position.
- 11. The method of claim 9 wherein said first valve is a cylinder exhaust valve and said second valve is a cylinder intake valve.
- 12. The method of claim 9 wherein said first valve is a cylinder exhaust valve and said second valve is a cylinder exhaust valve.
- 13. The method of claim 9 wherein said first valve is a cylinder intake valve and said second valve is a cylinder intake valve.
- 14. A method for controlling an engine, comprising:generating a current in the first ball-screw valve assembly communicating with a first engine cylinder while de-accelerating said first valve assembly towards a closed position; and, directing said current to a second ball-screw valve assembly communicating with a second engine cylinder to induce said second valve assembly to move towards an open position.
- 15. A system for controlling valve operation in an engine, comprising:a first control circuit coupled to a winding of a first plural phasor motor coupled to a first valve, said first valve controlling fluid communication with a first engine cylinder; and, a second circuit coupled to a winding of a plural phasor motor coupled to a second valve, said second valve controlling fluid communication with a second engine cylinder, wherein a current generated in the winding of said first motor while de-accelerating said first valve towards a closed position is routed through said winding of said first control circuit to said winding of second control circuit to induce said second valve to move towards an open position.
- 16. The system of claim 15 wherein said first and second motors are coupled to first and second ball-screw valves, respectively.
