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: An improved crankcase structure and manufacturing method for engine blocks and the like wherein the crankcase is initially cast or otherwise formed with bearing caps integral therewith. The caps are preferably secured by severable connecting portions unidirectionally longitudinally adjacent their associated bearing receiving portions in the transverse webs of the cylinder block. The complete crankcase is then machined and the bearing caps are separated for subsequent assembly to the crankcase in conventional fashion. The invention reduces the amount of tooling and machining time and equipment required for manufacturing crankcases for engine blocks and the like.

Abstract: A method is disclosed of modifying a conventional internal combustion engine to accept ceramic material. A cast iron extension mamber is metallurgically joined to the cast iron engine block, the extension member having a wall defining a bore opening aligned with and larger than the bore opening of the engine block. The extension member has a height substantially equal to or greater than the axial stroke of the piston. The diameter of the upper portion of the wall, defining the bore opening in the engine block, is enlarged to define an annular shoulder; the shoulder has an outer surface substantially axially aligned with the wall defining the bore opening in the extension member. A cylindrical ceramic liner, such as zirconia or alumina, is attached within the wall of the bore opening of the extension member by use of a high strength metallic sleeve which is fitted along the outer surface of the shoulder. The ceramic liner has an internal surface aligned with the wall of the bore opening in the engine block. A metallic cap (comprised of stainless steel or cast iron) is attached to the top of the piston, the cap carrying a ceramic facing. The cap has an effective height commensurate with the effective height of the extension member. The cap defines a trapped air space between the ceramic facing and piston, and the cap has its side wall aligned with the side wall of the piston.
