Publication number: 20160356241Abstract: A cylinder for opposed-piston engines includes a liner with a bore and longitudinally displaced intake and exhaust ports near respective ends thereof. An intermediate portion of the liner between the exhaust and intake ports contains a combustion chamber formed when the end surfaces of a pair of pistons disposed in opposition in the bore are in close mutual proximity. A compression sleeve encircles and reinforces the intermediate portion of the liner. An annular grid of pegs disposed between the intermediate portion and the compression sleeve supports the compression sleeve against the liner and defines a turbulent liquid flow path extending across the intermediate portion in a direction that parallels the longitudinal axis of the liner.Type: ApplicationFiled: June 5, 2015Publication date: December 8, 2016Applicant: ACHATES POWER, INC.Inventor: Kevin B.

Publication number: 20160356242Abstract: An engine cylinder bore with a plated bondcoat and a method of coating the surface of an engine cylinder bore. This method includes electroplating a bondcoat to the surface such that a substantial entirety of its inner circumference that corresponds to a piston travel path within the cylinder bore is covered. Cleaning or related pretreatment operations to properly activate the plated surface helps to ensure a durable coupling of a subsequently-applied thermal spray coating. In one preferred form, the cylinder bore is made from an aluminum-based alloy or a magnesium-based alloy that may be roughened prior to applying the bondcoat, while the bondcoat is plated using a titanium-based material such that a relatively thin TiO2 layer is formed on the cylinder bore. In another preferred form, the thermal spray coating is made of an iron-based material.Type: ApplicationFiled: June 8, 2015Publication date: December 8, 2016Inventors: Ronald J. Petrus, Martin S.

Publication number: 20160356243Abstract: The invention provides systems and methods for a network of cogenerations systems. In some cases, each system includes at least one cogeneration plant and at least one host facility, where the systems in the network are under the control of a common control system that optimizes a result for the network as a whole. In some cases, each cogeneration system in the network has an individual profile that is used by the control system for controlling that individual cogeneration system.Type: ApplicationFiled: June 3, 2016Publication date: December 8, 2016Inventors: Brian Mark Curtis, Riyaz Mohammed Shipchandler

Publication number: 20160356245Abstract: A nozzleless hybrid rocket motor includes a fuel element that defines a combustion chamber therewithin, in which combustion of the fuel and an oxidizer occurs. The combustion gases produced by the combustion between the fuel and the oxidizer transition to supersonic flow before leaving the fuel element, eliminating the need for a separate nozzle. The fuel element may be a part of a structural element of a vehicle, for example being a part of a fuselage, wing, fairing, or other part of a space vehicle or an air vehicle, with the fuel element an integral and continuous part of the structural element. Combustion of part of the fuel element may allow vehicle structure to be used to provide thrust, such as for maneuver, consuming part of the structure. The fuel element may be made by an additive manufacturing process.Type: ApplicationFiled: June 3, 2015Publication date: December 8, 2016Inventors: Jeremy C. Danforth, Teresa Perdue, Mark T.

Publication number: 20160356246Abstract: An attachment structure for a solenoid valve which can be stably attached to and removed from a carburetor unit with a single movement and without increasing the number of parts. A rod-like supporting portion is disposed a predetermined distance away from a surface of a carburetor unit and extending in a direction substantially perpendicular to a direction of and installed near an opening in the surface of the carburetor unit. A cylindrical engaging portion extends from a circumferential face of a cylindrical body fitted on the solenoid valve substantially perpendicular to an axial line of the rod-like supporting portion, and forms a groove-like engagement portion which is narrower in diameter than the rod-like supporting portion, whereby the engaging portion, via the groove-like engagement portion, is coupled to and supported by rod-like supporting portion when an insertion portion of the solenoid valve is inserted into the opening.Type: ApplicationFiled: June 2, 2015Publication date: December 8, 2016Inventors: Takumi Nonaka, Hideki Watanabe, Hiroyuki Oka
