    摘要: In a light alloy piston for use in diesel engines for an indirect fuel injection, a body of fibrous material is embedded in the cast piston head and is formed with a shallow combustion recess. In order to improve the conduction of heat outside the portion formed with the combustion recess, the body of fibrous material has a larger height on the side that is formed with the combustion recess than in the remaining portion of the piston head.

    摘要: In a light alloy piston for internal combustion engines, a fibrous insert body is embedded in the cast material adjacent to each of the bosses defining the piston pin bores. In order to minimize the costs of manufacturing such piston, the fibrous body extends only above the horizontal plane which includes the piston pin axis between that plane and the piston head and on both sides of the plane which includes the piston pin axis and the piston axis extends over not more than the load-carrying length of the boss defining the piston pin bore.

    摘要: A piston pin with a bore extending through it. To save weight and to optimize the shape of the pin with respect to accommodating stress, the diameter of the bore is increased to 75 to 90% of the outside diameter of the piston pin and reinforcing ribs are positioned in the bore in the vicinity of the inner edge of each hub.

    摘要: In a piston head of a multiple component piston for internal combustion engines, the piston floor continues radially outwards into the ring section which is provided with the piston ring grooves, the supports which carry the hubs are arranged at a distance from the inner face of the ring section and the piston pin which bears the piston shaft can be mounted in the bores of the piston pin boss. An improved manufacture of the piston head is ensured by connecting the ring section with the piston floor via a weld, solder, friction or positive locking joint.

    摘要: A piston rod for pistons of reciprocating piston machines is I-shaped in cross-section. In order to effect a reduction in weight that flange of the piston rod which is nearer to the connecting rod and is enbraced as by claws by the forked and hook-shaped end portion of the connecting rod has a smaller width than the flange which is nearer to the piston head.

    摘要: An arc welding process is used for form wear-resistant surfaces at least in the uppermost ring groove of aluminum alloy pistons for internal combustion engines. To reduce the manufacturing costs and to avoid an increase of the weight of the piston, the piston blank is formed by machining with a groove in at least one region to be provided with a ring groove having wear-resistant surfaces. During a rotation of the piston blank about its longitudinal axis said groove is entirely filled by arc welding with a filler material which comprises a silicon-containing aluminum alloy. The molten pool is solidified as quickly as possible by an adequate cooling. The ring groove is subsequently formed by machining.
