摘要： An engine valve actuation system is provided. The system includes an engine valve moveable between a closed position and an open position. A spring is operatively connected to the engine valve to bias the engine valve towards the closed position. An actuator is operatively connected to the engine valve and is operable to selectively engage the engine valve to prevent the engine valve from returning to the closed position and to release the engine valve to allow the engine valve to return to the closed position. A sensor is configured to provide information related to the operation of the actuator. A controller is configured to transmit a signal to the actuator to engage the engine valve to prevent the engine valve from returning to the closed position and to release the engine valve to the allow the engine valve to return to the closed position. The controller is further configured to receive a signal from said sensor and to identify when the actuator fails to engage the engine valve in response to the transmitted signal or when the actuator fails to release the engine valve.

摘要： A method of calibrating a variable valve actuation system is provided. An engine valve is moved from a first position where the engine valve blocks a flow of fluid to a second position where the engine valve passes a flow of fluid. A valve actuator is actuated to prevent the engine valve from returning to the first position. A signal is transmitted to cause the valve actuator and to allow the engine valve to return to the first position. The return of the engine valve to the first position is determined. A time parameter indicative of an elapsed time between the transmission of the signal and movement of the engine valve to the first position is determined.
