摘要： The invention concerns a method which consists in producing a fibrous structure by layering fibrous texture strata and mutually linking the strata by needle-bonding, such that the layered fibre strata extend substantially in orthogonal first (X) and second (Y) directions, the strata being mutually linked by fibres displaced in a third direction (Z) relative to the strata by the needle-bonding, and a piston preform is cut out in the needle-bonded structure such that one of the first and second directions (X, Y) is parallel to the generators of the preform surface corresponding to the piston lateral cylindrical surface. The preform is densified at least partially by the material constituting the composite material matrix and the piston is machined in the densified preform.

摘要： A carbon composite structure, for example, an automotive engine piston, is made by preparing a matrix comprised essentially of a mixture of non crystalline particulate soluble in an organic solvent and a binder that has a liquid phase. The non crystalline particulate also contains residual carbon hydrogen bonding. An uncured structured is formed by combining the matrix mixture, for example, carbon fibers such as graphite dispersed in the mixture and/or graphite cloth imbedded in the mixture. The uncured structure is cured by pyrolyzing it in an inert atmosphere such as argon. Advantagesoulsy, the graphite reinforcement material is whiskered prior to combining it with the matrix mixture by a method involving passing a gaseous metal suboxide over the graphite surface.
摘要翻译：通过制备基本上由可溶于有机溶剂的非结晶颗粒和具有液相的粘合剂的混合物组成的基质来制备碳复合结构，例如汽车发动机活塞。非结晶颗粒也含有残留的碳氢键。通过组合基质混合物，例如分散在混合物中的碳纤维（例如石墨）和/或嵌入混合物中的石墨布形成未固化的结构。未固化的结构通过在诸如氩气的惰性气氛中热解而固化。优点在于，通过使气态金属低氧化物在石墨表面上通过的方法，将石墨增强材料与基质混合物混合之前，进行研磨。

摘要： A piston (1) for a two-stroke crosshead engine has a number of ring grooves (2-4) for piston rings. At at least some of the rings the piston has pressure relief passages the axes of which avoid hitting the piston ring (14) at extension through the outlet openings (20). The total cross-sectional area expressed in mm of the pressure relief passages associated with the individual piston ring is in the interval from D /68000 to D /10000, D being the cylinder diameter expressed in mm.

摘要： Austenitic cast iron with mainly vermicular and/or nodular graphite is useful as a reinforcing material intermetallically bound to the aluminium base material of the pistons of an internal combustion engine. This material provides improved binding solidity with the adjacent aluminium base material of which the piston is made. The reinforcing material can be composed of different layers.

摘要： A piston assembly comprising a piston head, and a connecting rod one end of which is secured to the piston head so as to be pivoted relative to the piston head about a predetermined axis. The end of the connecting rod supports a cross-member opposite ends of which are received in respective recesses defined in the piston head. The recesses define arcuate bearing surfaces which are contacted by corresponding arcuate bearing surfaces defined by the cross-member. The piston head is formed from at least two components and each recess is defined by a respective one of the components. The components are permanently secured together after insertion of the cross-member into the recesses such that subsequent separation of the piston head and connecting rod is prevented. The piston assembly may support helical sealing rings.

摘要： Un pistón con alojamientos externos se conecta con al menos dos cigüeñales acoplados, transformando el movimiento reciprocante lineal del pistón en movimiento rotatorio de los cigüeñales. Una camisa de cilindro con la cabeza del pistón forma la cámara de combustión. El espacio interior del pistón con su contraparte estática forma una cámara de admisión-respiro adicional. En la contraparte estática, se pueden ubicar válvulas de ingreso y salida. A partir del movimiento reciprocante del pistón, la cámara de admisión-respiro proporcionará gases de admisión a la cámara de combustión empleando una lumbrera de transferencia. Antes de la lumbrera de transferencia, se puede disponer de una válvula de control para regular el volumen de gases de admisión que entran en la cámara de combustión. Los gases de admisión-respiro no utilizados para la combustión pueden mezclarse con los gases de escape de combustión. La longitud de las conexiones en configuración inversa, proporciona un tiempo adicional a la compresión en su máximo ratio; mejorando el tiempo de la etapa de evaporación y combustión.
