Abstract: A hollow poppet valve (10) is provided with an additional flange shape cavity (S1a), in addition to an ordinary valve head cavity (S1) formed in the valve head (14) of the valve (10) in communication with a valve stem cavity (S2) formed in a valve stem (12). A coolant (19) is loaded in the cavities to facilitate dissipation of heat out of the valve. This flange shape cavity (S1a) extends radially outwardly round a bottom portion of the valve head cavity (S1), extending close to a valve seat, thereby significantly facilitating heat transfer between the coolant (19) and the valve seat of the valve, yet, since the flange shape cavity (S1a) does not influences the thickness of other regions of the valve, it does not degrade durability of the valve.

Abstract: A valve for use in an internal combustion engine is disclosed. The valve includes a stem friction welded to a head portion. The head portion is cast from a single crystal metal using a casting process that creates little or no grain boundaries. The single crystal metal can be a nickel based superalloys such as CMSX-4, CMSX 3, Rene N5, and Rene N6. By having little or no grain boundaries, defects that occur in other types of casting material, such as large numbers of grain boundaries can be minimized. This allows the head portion and particularly the combustion face to withstand an operating temperature in the combustion chamber in excess of 850° C.

Abstract: 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.

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: For reducing the NOx-emission of a large sized two stroke diesel engine having at least one combustion room (3), a reciprocating piston (4) and an exhaust opening (12) controlled by an exhaust valve (13) at each work cyclus a small volume of burnt gas is retained in the combustion room (3) and so added to the fresh air for the next combustion. For achieving this retention of burnt gas the underside of the valve disc (15) off the exhaust valve (13) is provided with a shallow concave face (17) building a basin-like collection room, whose depth is within a range of 2-10% of the outer diameter of the valve disc (15).
