Abstract: The present disclosure relates to a system for controlling ignition of an air/fuel mixture intake charge directed into an internal combustion engine. The system may have a longitudinally movable inner cylinder liner configured to fit within a cylinder wall portion of an internal combustion engine, and able to receive a piston of the engine therein. A portion of the inner cylinder liner defines an internal volume forming a combustion chamber, and the internal volume controls a compression ratio of the cylinder. The system also has a cylinder head assembly operatively associated with the inner cylinder liner and able to move linearly to cause longitudinal displacement of the inner cylinder liner relative to the cylinder wall portion. This enables the volume of the combustion chamber to be further varied, to thus further vary the compression ratio.

Abstract: The present disclosure relates to a system for controlling ignition of an intake charge directed into an internal combustion engine. The system may have a movable component operably associated with at least one of a piston of the engine or a combustion chamber of the engine. The movable component may be tuned to deflect in response to a predetermined pressure being reached in a cylinder in which the piston is housed. The movable component operates to deflect in response to the predetermined pressure being reached in the cylinder as the piston travels toward top dead center during its compression stroke, to change a compression ratio of the engine.

Abstract: The present disclosure relates to a miniaturized fuel laboratory system that makes use of a housing, a processor housed within the housing, and a fuel inlet port supported from the housing for receiving a quantity of fuel to be used as a fuel test sample. The system may also have at least one fuel sensor housed in the housing in communication with the fuel inlet port for receiving the fuel test sample and carrying out combustion thereof. An electronic component may be housed in the housing, which enables communication with an external remote subsystem. A database may be incorporated which contains at least one of stored fuel characteristics or stored fuel analysis models, accessible by the processor. The processor may use fuel oxidation information generated by the fuel sensor, and at least one of the stored fuel characteristics or stored combustion models, to determine at least one fuel characteristic of the fuel test sample.

Abstract: A method for removing tritium from liquid lithium includes mixing the liquid lithium containing trace amounts of tritium with a molten salt and forming a salt of lithium and tritium. The method also includes separating the liquid lithium from the salt of lithium and tritium and circulating the molten salt in an electrolyzer to form molecular tritium. The method further includes bubbling an inert gas through the electrolyzer to remove the molecular tritium and circulating the argon and removed molecular tritium in a titanium getter to recover the tritium.

Abstract: An internal combustion engine. The engine includes at least one cylinder having a bore diameter, a piston for traveling within each cylinder between a first position and a second position, wherein the distance between the first position and the second position defines a stroke length, and thermal barriers on the surfaces of the combustion chamber near top dead center. In one embodiment, the engine utilizes asymmetric effective compression and expansion strokes. To maximize efficiency of the engine, a ratio of the bore diameter to stroke length of the internal combustion engine comprises a range between 0.5 to 1.0.

Abstract: A Homogeneous Charge Compression Ignition (HCCI) engine system includes an engine that produces exhaust gas. A vaporization means vaporizes fuel for the engine an air induction means provides air for the engine. An exhaust gas recirculation means recirculates the exhaust gas. A blending means blends the vaporized fuel, the exhaust gas, and the air. An induction means inducts the blended vaporized fuel, exhaust gas, and air into the engine. A control means controls the blending of the vaporized fuel, the exhaust gas, and the air and for controls the inducting the blended vaporized fuel, exhaust gas, and air into the engine.

Abstract: A work station, particularly for supporting a computer, having separate front and back tops having separate powered drive arrangements for permitting independently height adjustment. The drive arrangement includes a separate drive motor associated with each top, with the motors being controlled by a controller, such as a microprocessor. The controller is preferably controlled by an operator using a portable keypad control which can be positioned on one of the tops. The controller can be programmed by the operator to permit storage of a number of predetermined height locations each defining distinct heights for both tops.
