    Abstract: A method of high pressure die casting in iron alloy reinforcements for main bearing scantlings in an aluminum alloy engine block for an internal combustion engine. Prior to casting, reinforcements (1) having bores (6) for main bearing screws are placed in a die cavity (21), so that cores for main bearing screws protrude into the bores in each reinforcement on one side of the reinforcement. Then the reinforcements are fixed in the die cavity by placing a cylinder liner core (25) against a surface (27) of the reinforcement on the opposite side of the reinforcement.

    Abstract: A sintered powder metal (P/M) component has an integrally formed tapered boss surrounding its bolt hole which extends into counterbores in a component to which it is assembled and produces plastic conformance between the boss and the counterbore when the boss is seated in the counterbore. The P/M component can then be removed from the other component and reassembled to it, with the boss fitting perfectly back into the bore with the plastically deformed surfaces fitting back together precisely to determine the relative positioning of the two components. The boss is tapered, a moat may surround it, and the boss may be provided with axial splines and/or be oblong in the axial direction. Bosses such as these may be applied to two components in general, at least one of which is powder metal, such as a main bearing cap, a sensor ring for measuring the timing of an internal combustion engine and a connecting rod bearing cap. Such bosses may also be applied to a casting insert in which the boss is crushed when the die is closed so as to seal off the surrounded hole during casting.

    Abstract: For a machine housing with a split bearing arrangement, particularly journal bearing in piston machines, with a bearing cover clampably arranged via corresponding profiles on a bearing block, it is proposed that a bearing cover having a profile in its clamping face and acting as the tool electrode be used to produce by an electrical discharge machining process a corresponding profile in the clamping face of the bearing block of the machine housing serving as the workpiece electrode in order to achieve an advantageous formation of the profile. After the electrical discharge machining process, the bearing cover is mounted to the bearing block.

    Abstract: A reinforcing insert for an engine block formed of an engine block material is provided which is positioned in the bearing saddle area of the block for increasing the strength and stiffness of the bearing saddle area to ensure a secure connection of the main bearing cap throughout engine operation thereby ensuring proper crankshaft support and operation. The reinforcing insert is formed of a material having a higher modulus of elasticity than a modulus of elasticity of the engine block material. The insert includes a lower transverse surface for positioning at a lowermost position in the engine block, an upper surface positioned farthest from the crankshaft, a first and second linear side surfaces for positioning on opposite sides of the crankshaft. The linear sides extend from the lower surface along respective planes in nonparallel relation to each other. The linear sides may extend either in a converging or a diverging manner from the lower surface. Alternatively, the insert may include two cylindrical inserts positioned in bores formed in the block on opposite sides of the crankshaft. These insert designs provide strengthening and stiffening of the block over an optimum area while permitting secure attachment of a main bearing cap to the block.

    Abstract: A method of making a cast dual-metal monoblock, by (i) casting an iron-based insert to define walls for one or more chambers or passages for each of combustion, piston reciprocation, gaseous induction and gaseous exhaust; (ii) forming a sand core wrapping directly about said insert to cover such insert except for the extremities of the walls defining the passages for gaseous induction and exhaust and the chamber for piston reciprocation, such extremities being remote form the walls defining the combustion chamber; and (iii) die casting an aluminum-based metal jacket about the assembly of said insert and core wrapping to complete the dual-metal monoblock. Advantageously, in step (ii), there is further included the formation of a top sand core assembly for defining one or more oil and/or valve train passages or chambers, the top sand core assembly being stationed to rest on the insert during casting of the jacket.
