Abstract: A piston for an internal combustion engine comprising a piston head provided with at least one piston ring groove and a piston body having a piston pin bore, and a compression height of less than 40% of the piston diameter. In order to be able to equalize the influences of thermal expansion as well as possible and to enable a quiet operation of the piston in a cylinder, the invention provides that the largest diameter region of the piston body is arranged in a plane which extends perpendicularly to the body-generating line and which includes the piston pin axis.

Abstract: A cooled multi-component piston is provided in which the hollow annular space in the piston head for the cooling oil is closed off underneath. This is achieved with a sheet-metal ring with a collet which fits in a recess in the piston-ring wall, the sheet metal ring being biased via a retaining clip against the shaft bush.

Abstract: A surface hardened aluminum part having excellent heat resistance and abrasion resistance obtained by forming, on the surface of an aluminum base material, an alloy layer that has a uniform composition and uniform hardness, being free from cracks. An aluminum alloy powder made of aluminum and metals each of which forms an intermetallic compound of high hardness with aluminum is prepared. This aluminum alloy powder is supplied onto the aluminum base material and the aluminum or aluminum alloy contained in the aluminum base material is alloyed with the aluminum alloy powder using a high-density energy heat source to form an alloy layer. The alloy layer thus formed has an intermetallic compound of high hardness uniformly distributed throughout the layer so that the hardness of the alloy layer is uniform and cracking is unlikely to occur.

Abstract: Fastening devices such as washers, seals and drive pins subject to corrosive deterioration of all or select portions thereof wherein all or such select portions are protected from such corrosion and failure by a thin coating or coatings of hard surface material or materials. In a preferred form, the fastening device is coated with a synthetic diamond material formed as a thin layer in situ thereon. In addition to preventing moisture and other corrosive material from penetrating to the base metal, such synthetic diamond material serves to preserve the surface integrity of the fastening device preventing the formation or spread of surface flaws produced during use or during the fabrication of the fastening device.

Abstract: A low-friction piston construction for use in an oil-fed cylinder bore with the piston skirt relieved to define lands that are coated with SFL (graphite, MoS.sub.2, BN, and a special expoxy resin). A method of making such piston construction including provision of asperities on the skirt wall onto which the SFL coating is thermally sprayed and formation of small pockets at the mouth of the asperities to additionally act as oil replenishing reservoirs. A method of using such piston construction in an engine which comprises provisions of a slightly increased gap between the piston and cylinder wall and formation of a transferred SFL coating from the piston to the cylinder wall resulting in two polished microsmooth mating coatings, each attractive to oil films.

Abstract: Present day diesel engines having aluminum piston assemblies are limited to combustion chamber pressures of approximately 12,410 kPa (1,800 psi) whereas the desire is to increase such pressures up to the 15,170 kPa (2,200 psi) range. To reach such levels the instant piston assembly includes a steel piston member having an upper cylindrical portion defining a top surface, a depending tubular wall and an annular cooling recess having one or more machined surfaces of revolution about a central axis. The cooling recess is located beneath the top surface and juxtaposed to the top ring groove for removing heat away therefrom in use. The piston member is preferably forged and subsequently machined to precisely controllable dimensions. Moreover, the piston assembly is preferably of the articulated type and includes a forged aluminum piston skirt connected to the piston member through a common wrist pin.

Abstract: Piston tops (1, 70), specially those provided with combustion chamber (2, 20) and ring zone (3, 30) have their cooling condition sensibly improved in such regions due to a better use of the cooling oil capacity by closing the cooling chamber (5, 50) and the region 2I under the combustion chamber by annular ring members (96, 13) in a resilient material, e.g., a polymeric material or, preferably a spring steel, which clamp under the cooling chamber (5, 50) and the region 2I with dimensional interference respectively with grooves (10, 100), notches (11, 110) and groove 15. Methods for the manufacture of such top portion having a reduced compression height are also described.
