    Abstract: A method of flexibly manufacturing engine blocks by first bonding an extruded tube liner insert (12), of a given thickness (1-15mm), to a fixed configuration block (10), the liner insert having been coated with an anti-friction wear-resistant coating (59) having a controlled standard thickness, and secondly bonding another extruded tube liner insert (15) of a different thickness (again selected from 1-15mm) to another of the fixed configuration blocks, both liner inserts (12,15) having been coated with the same type of anti-friction wear-resistant coating in essentially the same controlled standard thickness. The common sized engine block (10) can have (i) identically shaped circular cylindrical bore walls or (ii) ovoid cylindrical bore walls with the liner insert having an interior surface shape selection varying between circular to ovoid. The block (10) and liner inserts (12,15) may be both made of aluminum. To promote wear-resistant and lubricant qualities, the coating (59) may contain a mixture of hard particles (such as stainless steel, nickel, chromium or vanadium) and solid lubricant particles such as oxides of iron having controlled oxygen, BN, LiF, NaF 2 or a eutectic of LiF/NaF 2 .

    Abstract: Les moteurs diesel actuels comportant des ensembles de pistons en aluminium sont limités à des pressions de chambre de combustion d'approximativement 12.410 kPa (1.800 spi) alors que les efforts de recherche visent à augmenter de telles pressions jusqu'à la plage de 15.170 kPa (2.200 psi). Afin d'atteindre de tels niveaux, le moteur de l'invention est doté d'une ensemble à piston (76) comportant un piston en acier (78) ayant une partie cylindrique supérieure (96) d'un diamètre D et définissant une surface supérieure (98), une paroi tubulaire dépendante (108) ayant une rainure annulaire supérieure (112) à une distance d'élévation minimum TRH en dessous de ladite surface supérieure (98), ainsi qu'une rainure de refroidissement annulaire (132) située en dessous de la surface supérieure (98), et juxtaposée à la rainure annulaire supérieure (112) afin d'en éliminer la chaleur lors du fonctionnement. Ledit piston (78) est de préférence forgé puis usiné à des dimensions commandées avec précision et a un rapport entre TRH et D inférieur à 0,06. De plus, ledit ensemble à piston (76) est de préférence du type articulé et comprend une jupe de piston (80) en aluminium forgé reliée audit piston par un maneton commun (82). La jupe comporte un creux à combustible orienté vers le haut, disposé dans une relation de coopération avec la rainure de refroidissement dudit piston. Une chemise (48) de cylindre à support intermédiaire entoure l'ensemble à piston (76) autour duquel est prévue une rainure à une élévation alignée avec la rainure annulaire supérieure (112) afin de maximiser le refroidissement.

    Abstract: Pistons are described comprising a crown portion (11) which also includes a piston ring belt and gudgeon-­pin bosses (18) and which crown portion comprises a ferrous alloy and a separate articulated skirt portion (12) which also includes gudgeon-pin bores (28,31,44,55) the crown portion and the skirt portion having a common gudgeon-pin wherein at least part of the skirt portion surfaces which co-operate with an associated cylinder or cylinder liner comprise a material selected from the group comprising aluminium alloys, plastics material and coated steel or cast iron. Examples are given of pistons having die-cast aluminium alloy skirts and skirts fabricated from sheet or strip metal.

    Abstract: A sliding device 1 includes a swash plate 3 rotated in association with a rotating shaft 2 and a plurality of semispherical shoes 4 sliding on the swash plate 3. The semispherical shoe 4 is formed of a ferrous material, and the swash plate 3 is manufactured using high-strength brass as a material. On a sliding surface 4A of the shoe 4, a large number of minute annular expandingly projecting parts 7' are formed by laser hardening, and a lubricating oil passage 10' consisting of a reticular concave part is also formed. Thereby, the sliding device 1 having excellent seizure resistance as compared with the conventional sliding device can be provided.
