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.

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 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： 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 power source may have at least one combustion chamber, a first valve configured to control an airflow between an air source and the at least one combustion chamber and a second valve configured to control an exhaust gas flow between the combustion chamber and an exhaust system. The power source may also have a fuel source configured to supply a fuel to the at least one combustion chamber and a controller operatively connected to the first valve and the second valve. The controller may be configured to determine one or more temperatures and, if the one or more temperatures are below a predetermined threshold, cause the first valve to substantially limit the airflow to the combustion chamber and cause the second valve to substantially limit the exhaust gas flow from the combustion chamber, such that a combustion stroke of one or more combustion cycles is executed with air substantially provided during an intake stroke of a previous combustion cycle.

摘要： An engine valve actuation system may include an actuation assembly having a body, a slidable piston, and first, second, and third chambers defined between the piston and the body. Low pressure and high pressure fluid sources may be included. A first fluid passage may connect the low pressure fluid source to the second chamber. A second fluid passage may connect the high pressure fluid source to the second chamber, and a third fluid passage may connect the high pressure fluid source to the third chamber. A control valve may be connected to the low pressure fluid source, to the high pressure fluid source, and to the first chamber. The control valve may be configured to move between a first position at which the high pressure fluid source is connected to the first chamber, and a second position at which the low pressure fluid source is connected to the first chamber.

摘要： A valve actuation system is provided. The system includes an engine valve moveable between a first position where the engine valve prevents a flow of fluid relative to the engine valve and a second position where the engine valve allows a flow of fluid relative to the engine valve. A first cam is rotated to move the engine valve from the first position to the second position during a first lift period. A second cam is rotated to affect movement of the engine valve between the first position and the second position during a second lift period. A phase shifting device is operatively connected to the second cam and is adapted to adjust the rotational phase of the second cam relative to the first cam, thereby adjusting the relative timing between the first lift period and the second lift period.
