    Abstract: A reinforcing insert for an engine block formed of a lightweight 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 lightweight 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 lightweight 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 from 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.
