    Abstract: 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.

    Abstract: In expansion-controlled light alloy pistons for internal combustion engines, expansion control elements made of steel are bonded to the carrying portions of the cast skirt on the inside peripheral surface thereof and are embedded in the hubs of the piston pin bosses. To provide for an optimum expansion control action throughout the height of the piston skirt, the expansion control elements are provided on both sides of the plane of oscillation of the connecting rod with an aperture, which is open toward the end of the skirt and has a height amounting to at least 30% of the height of the expansion control elements. Said aperture has a peripheral dimension amounting to more than 10% of the piston diameter. Projections for supporting the expansion control element at its edges defining the aperture protrude into the latter.

    Abstract: In a light alloy piston each of the load-carrying skirt surfaces is divided into a plurality of load-carrying skirt surface portions. In order to ensure that the upper portion of the piston skirt will carry load on a large area even when the engine is warming up, a plurality of depressions extending in the peripheral direction of the piston skirt are formed in the latter between its clearance-defining top and bottom ends.

    Abstract: A composite bearing material for use in the manufacture of crankshaft bearings comprises a steel strip, which is provided on one side, which is to be used disposed on the outside of the bearing, with an elastic layer, and on the other side, which is to be disposed on the inside of the bearing, with a bearing metal layer. In order to effect a sound insulation, in a particularly desirable manner the elastic layer consists of halogen-free polymers.

    Abstract: 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.

    Abstract: A method of manufacturing a steering wheel, in which a coating layer is molded of a synthetic resin, by using a molding die unit, on at least the annular portion of a steering wheel core including a boss. The annular portion is located around the boss and has a groove extending in the circumferential direction thereof. Spokes couple the boss and the annular portion to each other. The method includes a die opening step in which an upper molding die and a lower molding die, which have a gate formed at the separation surfaces of the dies and communicating with the molding cavity of the die unit, are opened from each other. The second step is a core setting step in which the core is set in the cavity so that the outermost part of the groove of the annular portion having walls defining the groove between them is located as the top of the groove, one of the walls, which faces the gate and has a notched part notched to be smaller in height than the other of the walls, faces the gate at the notched part, and the top of the notched part is located below the separation surfaces. Third, a coating layer molding step is carried out in which the dies are closed on each other and the resin is injected into the cavity through the gate so that the coating layer is molded of the resin on the core. Last and a steering wheel takeout step in which the dies are opened from each other and the wheel is taken out from the dies is accomplished.
