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.

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 controlling an engine is provided. At least one operating parameter of the engine is sensed. The engine is operated in a first mode in response to the sensed operating parameter being at one of a predetermined first set of conditions. In the first mode, a cam assembly moves an intake valve from a first position when a piston starts an intake stroke and the cam assembly returns the intake valve to the first position when the piston completes the intake stroke. The engine is operated in a second mode in response to the sensed operating parameter being at one of a predetermined second set of conditions. In the second mode, the cam assembly moves the intake valve from the first position when the piston starts an intake stroke and an actuator prevents the intake valve from returning to the first position in response to the cam assembly.

摘要： A method of controlling a variable valve actuation system is provided. A cam assembly is operated to move an intake valve between a first position where the intake valve blocks a flow of fluid and a second position where the intake valve allows a flow of fluid. At least one operating parameter of the engine is sensed. A valve actuation period is determined based on the at least one operating parameter. A valve actuator is engaged with the intake valve to prevent the intake valve from returning to the first position in response to operation of the cam assembly. The valve actuator is released to allow the intake valve to return to the first position at the end of the determined valve actuation period.

摘要： A method of controlling an engine during an engine startup or shutdown condition includes operating a valve to open a port of a combustion chamber to allow fluid to flow between the combustion chamber and the port for at least one entire engine cycle. The method also includes preventing combustion of fuel during a combustion stroke of the at least one engine cycle. The engine cycle occurs during the engine startup or shutdown condition.
