  • Electromechanical engine valve actuator system with reduced armature impact
    Patent number: 6701876
    Abstract: An electromechanical engine valve actuation system 10 is provided including a control element 16, a first actuator 18, a second actuator 20, an armature element 26 and a motion detector 32. The control element 16 controls the first actuator 18 and the second actuator 20 in response to the motion detector 32 in order to reduce the impact of the armature element 26.
    Type: Grant
    Filed: September 27, 2001
    Date of Patent: March 9, 2004
    Assignee: Visteon Global Technologies, Inc.
    Inventor: Xiang Youqing
  • ELECTROMECHANICAL ENGINE VALVE ACTUATOR SYSTEM WITH LOSS COMPENSATION CONTROLLER
    Publication number: 20030056741
    Abstract: An electromechanical engine valve actuation system 10 is provided including a loss compensation controller 16, a first actuator 18, a second actuator 20, an armature element 26 and a motion detector 32. The loss compensation controller 16 calculates the mechanical losses of the armature element and controls the first actuator 18 and the second actuator 20 in response to the mechanical losses in order to reduce the impact of the armature element 26.
