摘要： An engine block assembly and method manufacturing an engine block assembly and related components. A casted engine block assembly includes a cylinder block portion. The cylinder block portion includes a plurality of cylinder block openings disposed therein, a cylinder block flange portion positioned at a top of the cylinder block portion and a cylinder block crankcase portion disposed at a base of the cylinder block. The cylinder block flange portion is configured for coupling the cylinder block to a cylinder head. The cylinder block portion includes a plurality of cylinder block walls extending between the cylinder block flange portion and the cylinder block crankcase portion and positioned about the plurality of cylinder block openings. The cylinder block walls house a plurality of internal channels. The plurality of cylinder block walls are void of enclosed openings extending through at least one of the cylinder block walls in the plurality of cylinder block walls.

摘要： An engine block, an engine sub-assembly, and method for providing and manufacturing an engine block. The engine block includes a plurality of cylinder barrels positioned in the engine block, at least one oil jacket channel formed in the engine block, and an oil inlet port positioned in a peripheral wall of the engine block and connected to the at least one oil jacket channel. The at least one oil jacket channel includes a plurality of curved channel sections. Each curved channel section in the plurality of curved channel sections extends about at least a portion of a circumferential portion of a respective cylinder barrel in the plurality of cylinder barrels. The at least one oil jacket channel extends between adjacent cylinder barrels of the plurality of cylinder barrels in the engine block.
