A cylinder block is provided. The cylinder block includes a cylinder, two crankshaft supports at a bottom of the cylinder block, a cylinder head engaging surface at a top of the cylinder block, and first and second exterior sidewalls, the first exterior sidewall extending from the cylinder head engaging surface to a first structural frame engaging surface positioned above a centerline of the two crankshaft supports.

METHOD FOR THERMAL CONTROL OF CAST-IN COMPONENTS DURING MANUFACTURING
20170087628 · 2017-03-30 ·

A method for forming a product having cast-in components provides an insulating barrier of solidified sand formed next to the insider diameter of the cast-in component. The center of the solidified sand is hollow. Before pouring the molten metal into the primary runner/riser system that feeds the portion of the mold that will create the actual part, the molten material is poured into the hollow portion of the solidified sand through a separate runner/riser system. This molten metal provides the energy necessary to heat the cast-in part to an acceptable temperature. The temperature can be controlled by the shape, thickness and material of the insulating member. This controlled time/temperature profile enables the creation of a final cast product that demonstrates good quality properties at the cast/insert interface. The method of the disclosed inventive concept has the added benefit of not altering the resulting part itself.

INTERNAL COMBUSTION ENGINE HAVING STRUCTURAL FRAME

A structural frame is provided. The structural frame includes a bottom surface, first and second cylinder block sidewall engaging surfaces, the first and second cylinder block sidewall engaging surfaces positioned above the bottom surface at a height that is above a centerline of a crankshaft support included in a cylinder block when the structural frame is coupled to the cylinder block.

LUBRICATION CIRCUIT AND METHOD OF FORMING

An engine has a cylinder block formed by a block material and defining at least one cylinder. The block defines a lubrication circuit with fluid passages including an inlet passage, a main oil gallery, a crankshaft bearing lubrication passage, and a piston ring lubrication passage. The fluid passages are formed by continuous metal walls in contact with and surrounded by the block material. At least one of the fluid passages is curved. A method of forming a component with an internal pressurized lubrication circuit includes positioning a lost core insert in a tool, with the insert shaped to form a lubrication circuit. The lost core insert has a lost core material generally encapsulated in a continuous metal shell, and at least one curved section. Material is provided into the tool to form a body surrounding the lost core insert thereby forming a component preform.
