Abstract: A method is provided for designing and producing fiber-reinforced polymer (FRP) pistons. Pistons made with FRP have a lower mass than prior art metal pistons conferring advantageous engine efficiency and stability. FRP pistons also increase the thermal efficiency of engines by having a lower thermal conductivity, with tighter piston-to-bore clearance, and/increased air-fuel ratio than pistons of metal. The technical parameters of the piston are identified, and a piston body blank is produced. The blank is then machined, a bearing surface for the pin bore is created, the piston blank is optionally coated, is optionally subjected to Heavy Metal Ion Implantation (HMII) treatment and is subjected to sodium silicate impregnation to produce the final pistons.

Abstract: A hinged-vane rotary pump is disclosed. The pump includes a rotor eccentrically disposed within a chamber and having attached thereto at least two vanes movable between a retracted position and an extended position. At least one friction reducer is attached to each vane, wherein the friction reducer contacts the wall of the chamber when its corresponding vane is in the extended position, and also prevents the second end of its corresponding vane from contacting the peripheral wall when the corresponding vane is in the extended position.

Abstract: A sintered powder metal (P/M) component has an integrally formed tapered boss surrounding its bolt hole which extends into counterbores in a component to which it is assembled and produces plastic conformance between the boss and the counterbore when the boss is seated in the counterbore. The P/M component can then be removed from the other component and reassembled to it, with the boss fitting perfectly back into the bore with the plastically deformed surfaces fitting back together precisely to determine the relative positioning of the two components. The boss is tapered, a moat may surround it, and the boss may be provided with axial splines and/or be oblong in the axial direction. Bosses such as these may be applied to two components in general, at least one of which is powder metal, such as a main bearing cap, a sensor ring for measuring the timing of an internal combustion engine and a connecting rod bearing cap. Such bosses may also be applied to a casting insert in which the boss is crushed when the die is closed so as to seal off the surrounded hole during casting.

Abstract: An internal combustion engine comprises an aluminum alloy engine block housing pistons in cylinders and having a lower face including an upper semi-circular bearing surface. A lower bearing support has a lower semi-circular bearing surface to complement the upper semi-circular bearing surface in the engine block to define a crankshaft bore to rotatably support a ferrous crankshaft. The lower bearing support is formed of a single beryllium-aluminum alloy having a coefficient of thermal expansion comparable to the ferrous crankshaft to promote a consistent clearance between the lower bearing support and the crankshaft. Such a beryllium-aluminum alloy may be comprised of approximately 60-65% by weight beryllium and the balance is aluminum.
