摘要： The reinforcement plate for a reciprocating engine greatly reduces relative movement of the main bearings of a reciprocating engine, thereby reducing structural fatigue to increase engine durability and longevity. The reinforcement plate also maintains a more precise alignment between the main bearings to reduce friction during operation. The plate comprises a flat, planar steel sheet having opposite sides which fit within the lower skirt of the engine block. A series of lateral ribs or bars extend across the plate and bolt to all of the main bearing caps of the engine, using the stock cap bolts. Crankshaft counterweight and crank throw clearance openings, as well as other clearance areas, are provided in the plate. The reinforcement plate is adapted particularly well for installation in General Motors LS-1 aluminum block engines, but may be configured for installation in a number of different engines as desired.

摘要： A method of forming an assembly is provided. The method includes forming an insert, coating the insert with a bond material and placing the insert within a casting mold or die. The casting mold or die is purged with an inert gas and the casting mold or die is filled with molten metal to encapsulate the insert. The encapsulated insert is diffusion bonded to the molten metal to form a diffusion bonded insert, which is placed within a cavity of a secondary casting mold or die. The secondary casting mold or die is filled with molten metal to form a composite casting assembly. After or during the casting, the composite casting assembly is heat treated. In another method of the present disclosure, the insert includes ferrous alloys, nickel-based alloys, super alloys, and nonferrous alloys.

摘要： A ladder frame for an internal combustion engine includes a first lateral wall and a second lateral wall, crank caps, and first joining portions and second joining portions. Each crank cap includes an arc-shaped center portion, a first lateral portion and a second lateral portion. Each first lateral portion is joined to the first lateral wall via each first joining portion, and each second lateral portion is joined to the second lateral wall via each second joining portion. Each center portion includes a supporting portion that rotatably supports the crankshaft, the center portion including a recess to which the residual portion is joined, on the opposite side to the supporting portion. Respective thicknesses of the first lateral portion and the second lateral portion are the same as that of the center portion. The recess is provided with a projection embedded in the residual portion.

摘要： An assembly, a crankcase, a reciprocating internal combustion engine, and a method for producing a reciprocating internal combustion engine facilitates engine block cleaning after casting, enables current and future residual-soiling standards to be met, and provides a solution to the challenges facing current and future high-performance engines, in particular the load zones head plate and cylinder tube, as well as potential for local improvement to properties in the crankcase in the additional load zones, namely the screw connection connecting the cylinder head and the crankshaft bearing. The assembly includes at least two cylinders and a platelike deck plate connecting them of integral design, wherein the platelike deck plate has a clearance for each cylinder and wherein the assembly can be inserted into or placed upon a crankcase of a reciprocating internal combustion engine, in that at least one coolant guideway is arranged between the cylinders.
