摘要： Systems and methods are provided for a cylinder block having one or more bulkheads. The bulkheads provide a dual-wall structure that may enhance the stiffness of the cylinder block in bending and torsion. The bulkheads may also provide an oil drain to allow oil to directly drain through a hollow core of the bulkhead. An overflow outlet may be formed in an inner wall of a bulkhead. In some implementations, a cylinder block with bulkheads may increase an oil capacity of an engine.

摘要： The present invention is an internal combustion engine composed of a plurality of cylinders arranged into banks. Located near the mid-point of each bank of cylinders is a section formed with passages that are configured to provide distribution and recovery of cooling and lubrication fluids. This section is located such that the path of these fluids begins and ends at a mid-point so as to provide a shortened path across each half of the bank of cylinders within which the section is located.

摘要： A housing for an internal combustion engine is provided with a bore, which is formed by at least two bore sections at a distance from each other. The bore may be a bearing tunnel in a crankcase or a cylinder head of the internal combustion engine. A rotating, machining tool is provided to machine the bore. The tool is introduced into the bore by axial displacement and the bore is used as a counter-bearing for the tool for radially supporting the tool. The counter-bearing is in one piece with the housing.
