    摘要: A piston assembly including a piston body pivotally connected to a connecting rod by a wrist pin. The wrist pin includes a sealed cavity therein partially filled with a heat transfer medium. The heat transfer medium may be composed of a fusible alloy. The sealed cavity may be comprised of discrete compartments. The wrist pin may be integrated with the connecting rod and share a conjoined sealed cavity therewith so that heat transfer medium can draw heat effectively away from the piston body.

    摘要: A wet-style cylinder liner (16) for a diesel engine is provided with a surface texture (28) to combat the effects of cavitation-induced erosion. The surface texture (28) can be formed as a coating (30) of manganese phosphate applied about the outer surface (26) of the cylinder liner (16) within the coolant flow passage (20) of the engine. The manganese phosphate is applied in such a manner that a crystalline structure of 2–8 μm average grain size, blocky in nature, clearly faceted, with no cauliflower-like formations and a discernable channel network surrounding the crystals is formed. This crystalline structure works with the natural adhesion and surface tension effects within the liquid coolant to create a stagnant fluid layer about the outer surface (26) of the cylinder liner (16). The stagnant fluid layer functions like a self-healing armor plate. When rapid flexing of the cylinder liner (16) produces cavitation bubbles, these bubbles are held at a distance from the outer surface (26) by the stagnant fluid layer. As the bubbles implode, their kinetic energy is dissipated within the stagnant fluid layer instead of directly upon the outer surface (26) of the cylinder liner (16). The manganese phosphate coating (30) acts as a labyrinth to anchor water molecules, or the engine coolant, and thus promote formation of the stagnant fluid layer.

    摘要: A piston has a pair of diametrically opposite skirt portions with convex outer surfaces. Each skirt portion has opposite side edges extending substantially parallel to a central axis of the piston to a free end. The skirt portions each have a recessed slot extending radially into the convex outer surface to a recessed surface. The recessed surface extends fully across the convex outer surface to the side edges and separates an upper band section of the convex outer surface from a lower band section of the convex outer surface.

    摘要: A process and apparatus utilizing at least one conformable anode (40) in a plating process to apply a plating to an article (10). A wire or other material suitable for an anode is shaped to conform to the approximate shape of a region of the article to be coated. The anode is powered by an electrical power source (44), and the article serves as the cathode. The anode and article are both immersed in a plating bath (38). The article and anode are rotated relative to one another about a central axis (22) of the article. The relative movement between the anode and the article causes a uniform plating (46) to be applied to selected regions of the article that pass the anode. Another anode (50) can be arranged in fixed relation with the article to cause plating to a separate selected region of the article concurrently with the other anode.
