摘要： An aspect of the present disclosure relates to a fluid bearing and a method of adjusting the load carrying capacity of a fluid bearing. The fluid bearing may include a bore defined in the fluid bearing and a rotatable bearing including a rotatable bearing surface. Lubricating fluid in the bore may be contacted with at least a portion of the rotatable bearing surface, wherein an effective bearing surface area is provided where the lubricating fluid contacts the rotatable bearing surface. The effective bearing surface area may be altered by either increasing or reducing the area of the rotatable bearing surface which is contacted by the lubricating fluid.

摘要： A piston for a direct injection engine is provided, the piston having a bowl at an upper end, the bowl forming a portion of a combustion chamber. The bowl includes an inner surface that defines a volume configured to receive a fuel-air mixture, the inner surface of the bowl including a generally concave portion including a flat bottom surrounding a central protruding dome. The relatively flat bottom portion is bounded by two radial concave surface portions which are disposed below two convex separation features for the injected fuel spray. Such surface geometries may reduce soot and improve fuel-air mixing.

摘要： A multizone combustion chamber and method of combustion in a compression-ignited reciprocating engine. The combustion chamber includes a cylinder, a cylinder head located at one end of the cylinder, a piston that reciprocates in the cylinder, an inlet that supplies a gas into the combustion chamber during an induction stroke of the piston, and an injector that supplies a fuel into the combustion chamber. The combustion chamber defines a primary chamber and at least a secondary chamber when the piston is located in a predetermined position near the cylinder head. Combustion is initiated in the primary chamber while preventing combustion from occurring in the secondary chamber. Combustion in the secondary chamber is delayed until after the piston and the cylinder head have been separated and thermodynamic communication between the fuel/gas mass in the primary chamber and the fuel/gas mass in the secondary chamber is possible.

摘要： A removal torque-resistant closure and container assembly is provided with the container having a thread extending around the opening. The closure includes a thread for engaging the container thread. The container includes a projection that extends from the thread root between two adjacent thread crests on the container and that defines an outer edge for temporarily deforming the closure thread during relative rotational movement of the container and closure when the container and closure are screwed together. Upon termination of the screwing action, the container projection edge is engaged with a deformed region of the closure thread so as to resist closure removal by unscrewing.
