Abstract: A mechanically controllable valve operating mechanism includes a cylinder head, a camshaft, a transmission arrangement mounted to move in the cylinder head via a bearing device. A gas exchange valve has the transmission arrangement act thereon. A valve-lift adjusting device comprises a rotatable adjusting element with an eccentric element having two base points and a peak contour, and at least one further eccentric element. The valve-lift adjusting device acts on the transmission arrangement so that different valve-lift positions are settable. The transmission arrangement is connected to the valve-lift adjusting device and to the camshaft. The at least one further eccentric element of the rotating adjusting element is arranged so that at least two peak contours are provided so that, depending on a rotational angle α of the rotating adjusting element, the eccentric element or the at least one further eccentric element engage with the transmission arrangement.

Abstract: 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.

Abstract: An early intake valve closing (EIVC) and variable valve timing (VVT) assembly and method are provided for an internal combustion engine. The method includes operating an intake valve to open and close an intake port and allow intake gas to enter a cylinder of the internal combustion engine containing a piston, where the timing of the closing of the intake valve occurs at or before bottom dead center (BDC) of the compression stroke of the piston. The method further includes selectively extending duration of the opening of the intake port by an amount that delays closing timing of the intake valve until after BDC of the piston compression stroke. An assembly for EIVC and VVT includes a cylinder head including an intake valve and intake port and a rotatably mounted camshaft including an intake lobe operatively connected to the intake valve to periodically move the valve into the first and second positions. The intake lobe is shaped such that the timing of the closing position occurs at or before BDC of a compression stroke of the piston. The assembly further includes a selectively activatable VVT assembly having an actuator that operatively engages the intake valve before the intake valve reaches the closed position to extend duration of the intake valve opening until after BDC of the piston compression stroke.
