Adjusting electrically actuated valve lift

A method to adjust lift amount of an electrically actuated valve, said electrically actuated valve having a valve actuator comprising an armature, an armature plate having a permanent magnet, and at least a coil, said electrically actuated valve operating in a cylinder of an internal combustion engine, the method comprising:

• moving said armature plate of said electrically actuated valve so that said electrically actuated valve is moved from a closed position to an open position by adjusting current flow to a first coil of said valve actuator;
• and
• adjusting current flow to a second coil of said valve actuator to repel said armature plate from said second coil as said electrically actuated valve moves to said open position.

A method to adjust lift amount of an electrically actuated valve, said electrically actuated valve operated in a cylinder of an internal combustion engine, the method comprising:

• moving said electrically actuated valve open by adjusting current flow to said electrically actuated valve;
• and
• adjusting current flow to said open electrically actuated valve so that forces acting on said electrically actuated valve cause said valve to begin to close immediately after said valve reaches a lift amount.

A method to adjust lift of an electrically actuated valve, said electrically actuated valve having a valve actuator comprising an armature, an armature plate having a permanent magnet, and at least a coil, said electrically actuated valve operating in a cylinder of an internal combustion engine, the method comprising:

• moving said armature plate of said electrically actuated valve so that said electrically actuated valve is moved from a closed position to an open position by controlling current flow to a first coil of said valve actuator;
• adjusting current flow to a second coil of said valve actuator to attract said armature plate to said second coil, and so that forces acting on said armature cause said valve to begin to close immediately after said valve reaches a lift amount.

A method to adjust lift amount of an electrically actuated valve, said electrically actuated valve operating in a cylinder of an internal combustion engine, the method comprising:

• opening and closing said electrically actuated valve by adjusting current flow to an opening coil and a closing coil of said electrically actuated valve, said electrically actuated valve opened a valve lift amount, during a cycle of said cylinder;
• and
• varying said valve lift amount in response to a signal during a subsequent cycle of said cylinder.

A computer readable storage medium having stored data representing instructions executable by a computer to control an electrically actuated valve in a cylinder of an internal combustion engine of a vehicle, said storage medium comprising:

• instructions for operating said electrically actuated valve at a first valve opening lift amount, by adjusting current flowing to a valve opening coil, at a first engine operating condition;
• and
• instructions for operating said electrically actuated valve at a second valve opening lift amount, by adjusting current flowing to said valve opening coil, at a second engine operating condition.
