    Abstract: A bearing arrangement which assures positive geometrical centering between two separately produced bearing components, preferably in internal combustion engines, includes a first bearing component provided with projections extending beyond a parting surface between the components and a second bearing component of lower hardness than the projections so that the projections displace the material of the second bearing component during assembly of the bearing arrangement.

    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: The crankshaft bearing for an internal combustion engine consists of two bearing sections bolted together, in which an insert made of a ferrometallic material is embedded in a casting made of a light metal alloy. The inserts consist of shaped molded parts with openings and thickenings as well as a semicircular carrier that receives the respective part of the bearing bore. The inserts are traversed by the bearing bolts, which on one side abut the outer bolt surfaces on the casting of one bearing section and are bolted into the casting of the other bearing section.

    Abstract: A bearing insert for being cast into an aluminum alloy engine block is made by a ferrous powder metal sintering process to make a skeleton structure which is permeable to the molten aluminum alloy in the block casting process. The insert is made of a material having a similar composition as the bearing cap so as to equalize machining and thermal expansion properties of the cap and block so as to provide improved roundness of the bearing in the machining operations for forming the bearing support and in operation of the engine.

    Abstract: A cylinder block for an engine is formed of a cylinder block body and a lower block which are cast from aluminum alloy and are fastened together to support therebetween a crankshaft of the engine. The upper half of a bearing portion for supporting the crankshaft is provided in the cylinder block body and the lower half of the bearing portion is formed by a bearing cap cast in the lower block. A method of manufacturing the cylinder block includes the steps of casting the cylinder block body and the lower block with the bearing cap cast in the lower block, fastening together the cylinder block body and the lower block by bolts, performing primary stage finishing of the bearing portion with the cylinder block body and the lower block kept fastened together, releasing the lower block from the cylinder block body after the primary stage finishing of the bearing portion and permitting the lower block to deform under stress produced by shrinkage of aluminum alloy, fastening again the cylinder block body and the lower block together by the bolts, and performing final stage finishing of the bearing portion with the cylinder block body and the lower block kept fastened together.

    Abstract: A crankshaft supporting structure in a multicylinder internal combustion engine has a cylinder block made of a light alloy and including a cylinder housing and a crankcase having a plurality of spaced journal walls. A plurality of spaced bearing caps made of an iron alloy are coupled respectively to the journal walls. A crankshaft is rotatably supported in bearing holes defined by the journal walls and the bearing caps. A bridge made of a light alloy extends across the bearing caps and is coupled to the bearing caps. The bearing caps and the bridge are fastened together to the journal walls by connecting bolts disposed one on each side of the crankshaft. The bridge has a main portion defining a main gallery extending longitudinally therethrough and a plurality of legs coupled to the bearing caps, respectively. The bearing caps and the legs jointly define branch oil passages communicating with the main gallery and the bearing holes. In one embodiment, each of the oil passages has a longitudinal central axis displaced transversely from the central axis of the cylinder housing passing through the center of the crankshaft.
