    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: Disclosed is an engine that comprises an engine block, and the engine block comprises a cylinder. The engine further comprises a cylinder head mounted to the engine block, and the cylinder head comprises an intake valve seat and a shroud. Further yet, the engine comprises a combustion chamber formed at least partially by the cylinder and the cylinder head. The intake valve is configured to travel between a fully closed position seated against the intake valve seat and an opened position displaced from the intake valve seat, thus allowing intake flow through the intake valve seat into the combustion chamber. The shroud only partially surrounds a periphery of the valve and extends along at least a portion of the travel of the intake valve so as to restrict intake flow along only a portion of the intake valve.

    Abstract: Disclosed is a valve seat lubrication oil coating device. More specifically, an oil pan is filled with lubrication oil and configured so that a valve seat partially soaks therein. An oil tank is equipped with a hydraulic pump, and an oil pan oil supplier supplies oil to the oil pan via the hydraulic pump from the oil tank. Additionally, a coating oil supplier coats an outer circumferential surface of a portion of the valve seat, which is not being soaked in the oil, with the oil from the oil tank.

    Abstract: A heat transferring engine valve for an internal combustion engine to increase the combustion efficiency and fuel economy of the engine. The heat transferring valve includes a valve head and a heat transferring member situated at the combustion surface of the valve head and extending toward the combustion chamber. The heat transferring member absorbs heat of combustion during the power stroke of an engine cycle and releases the heat into the combustion chamber during the compression stroke of a succeeding engine cycle, thereby raising the temperature of fuel at the start of combustion. A method for increasing the efficiency of combustion in an internal combustion engine by incorporating at least one heat transferring valve into the engine.
