摘要： A spark-ignition supercharged internal-combustion gasoline engine is equipped with a system for variable actuation of the intake valves including a pressurized fluid chamber set between intake valve and a respective control cam, and an electrically actuated valve, the opening of which vents the pressure chamber so as to cause rapid closing of the valve, as a result of the respective elastic return means, even when the respective cam would tend to keep the valve open. The variable-valve-actuation system is used in combination with control cams of the intake valves shaped in such a way as to generate an intake valve lift profile including a boot portion with substantially constant lift. The boot portion is provided in the final part of the opening cycle of the intake valve, after bottom dead center.

摘要： A camshaft for an internal combustion engine, having a hollow outer shaft and an inner shaft which is concentrically mounted inside the outer shaft to be rotatable about an angle and a multi-part cam element having a first cam section that is mounted on the outer shaft in a rotationally fixed manner and a second cam section that is connected to the inner shaft in a rotationally fixed manner and rotationally mounted on the outer shaft. The two cam sections have different cam contours, the relative movement of the two cam sections in opposite directions allowing the resulting cam contour of the cam element interacting with a cam follower to be changed to adjust the variable valve opening period. The two cam sections have different maximum lifts, the cam top section of the cam section having the smaller maximum lift being substantially formed by an annular sector.

摘要： An engine valve actuation system is provided. The engine valve actuation system includes an intake valve that is moveable between a first position to prevent a flow of fluid and a second position to allow a flow of fluid. A cam assembly is configured to move the intake valve between the first position and the second position. A fluid actuator is configured to selectively prevent the intake valve from moving to the first position. A source of fluid is in fluid communication with the fluid actuator. A directional control valve is configured to control a flow of fluid between the source of fluid and the fluid actuator. A fluid passageway connects the directional control valve with the fluid actuator. An accumulator is in fluid communication with the fluid passageway. A restricted orifice is disposed between the accumulator and the fluid passageway to restrict a flow of fluid between the accumulator and the fluid passageway.

摘要： A valve actuation system is provided. The system has an engine valve moveable between a first position at which the engine valve prevents a flow of fluid relative to the engine valve and a second position at which fluid flows relative to the engine valve. The system also has a first cam adapted to move the engine valve from the first position to the second position during a first lift period in response to a rotation of the first cam. The system has a second cam adapted to move the engine valve from the first position to the second position during a second lift period in response to a rotation of the second cam. The system also has a cam following assembly disposed between the first and second cams and the engine valve. The cam following assembly is adapted to selectively connect one of the first and second cams with the engine valve to thereby move the engine valve through one of the first and second lift periods.
