摘要： Devices and related methods are disclosed that generally involve variable force valve springs for controlling the motion of an engine valve. The force exerted by the valve spring can be adjusted by altering the pressure at which a fluid is supplied to a fluid chamber thereof, by altering the volume of the fluid chamber, and/or by changing the aggregate surface area over which fluid pressure is coupled to the engine valve. Associated fluid control systems are also disclosed herein, as are various methods for adjusting the force of a valve spring based on a variety of engine parameters, such as engine speed, engine load, and/or a combination thereof.

摘要： Devices and related methods are disclosed that generally involve the selective deactivation of one or more engine valves. In one embodiment, a split-cycle internal combustion engine is provided in which a high-speed trigger valve is used to fill and drain a hydraulic tappet that forms part of a lost-motion system of an engine valve. A spool valve can be used to selectively disconnect the tappet from the trigger valve, thereby deactivating the associated engine valve (i.e., preventing the engine valve from opening). The devices and methods disclosed herein also have application in conventional internal combustion engines and can be used with inwardly-opening and/or outwardly-opening valves.

摘要： Valve actuation systems are disclosed herein that allow valve opening timing to be varied using a cam phaser and that allow valve closing timing to be varied using a lost-motion system. In one embodiment, an actuation system is provided that has a locked configuration in which a bearing element is held in place between a cam and a rocker to transmit cam motion to an engine valve. The actuation system also has an unlocked configuration in which the bearing element is permitted to be at least partially ejected from between the cam and rocker, such that cam motion is not transmitted to the engine valve. The actuation system is switched to the unlocked configuration by draining fluid therefrom through a main valve which is piloted by a trigger valve. The actuation system also includes integrated autolash and seating control functionality.

摘要： Methods and apparatus for actuating an engine valve provided between an engine cylinder and an exhaust manifold to provide compression-release engine braking in combination with exhaust gas restriction and brake gas recirculation are disclosed. In a first embodiment of the present invention, the engine valve used to provide brake gas recirculation and compression-release braking may be maintained slightly open between the brake gas recirculation and compression-release events. In another embodiment of the present invention, the cam closing ramp for a main exhaust event may be extended to terminate near the beginning of a brake gas recirculation event to facilitate refilling a hydraulic valve actuation system used to in association with the exhaust valve.
