Abstract:
A method of operation for an engine including an electrically actuated engine valve in a cylinder head, with at least an actuator coupled to the valve, the method including applying a potential to generate a current indicative of temperature in the actuator at least partially during a substantially non-moving condition of the actuator and adjusting a timing of the application of the potential based on valve location in the cylinder head.
