    Abstract: A sintered powder metal (P/M) component has an integrally formed tapered boss surrounding its bolt hole which extends into counterbores in a component to which it is assembled and produces plastic conformance between the boss and the counterbore when the boss is seated in the counterbore. The P/M component can then be removed from the other component and reassembled to it, with the boss fitting perfectly back into the bore with the plastically deformed surfaces fitting back together precisely to determine the relative positioning of the two components. The boss is tapered, a moat may surround it, and the boss may be provided with axial splines and/or be oblong in the axial direction. Bosses such as these may be applied to two components in general, at least one of which is powder metal, such as a main bearing cap, a sensor ring for measuring the timing of an internal combustion engine and a connecting rod bearing cap. Such bosses may also be applied to a casting insert in which the boss is crushed when the die is closed so as to seal off the surrounded hole during casting.

    Abstract: In order to prevent a damage on a component forming a pressure feed fuel passage and to reduce a fuel injection pump in size and weight, the pressure feed fuel passage having fuel discharge passage, fuel chamber and accommodation hole formed in respective cylinder heads is formed straightly in respective cylinder heads, and has communication port for communicating with fuel pressure chamber and fuel outlet which has an opening at an outer peripheral wall of the cylinder heads. Fuel pressurized in fuel pressure chamber at the cylinder head side is introduced into fuel chamber of cylinder head via fuel passage and fuel lines. Fuel pressurized in both fuel pressure chambers is merged at fuel chamber of cylinder head, and is supplied to a common-rail via fuel passage.

    Abstract: A reinforcing insert for an engine block formed of an engine block material is provided which is positioned in the bearing saddle area of the block for increasing the strength and stiffness of the bearing saddle area to ensure a secure connection of the main bearing cap throughout engine operation thereby ensuring proper crankshaft support and operation. The reinforcing insert is formed of a material having a higher modulus of elasticity than a modulus of elasticity of the engine block material. The insert includes a lower transverse surface for positioning at a lowermost position in the engine block, an upper surface positioned farthest from the crankshaft, a first and second linear side surfaces for positioning on opposite sides of the crankshaft. The linear sides extend from the lower surface along respective planes in nonparallel relation to each other. The linear sides may extend either in a converging or a diverging manner from the lower surface. Alternatively, the insert may include two cylindrical inserts positioned in bores formed in the block on opposite sides of the crankshaft. These insert designs provide strengthening and stiffening of the block over an optimum area while permitting secure attachment of a main bearing cap to the block.

    Abstract: A cylinder head for an internal combustion engine, having an iron lower base part with inlet and exhaust ports and controlling valves therefor and an aluminum upper support for the camshaft and valve tappets. The upper part includes an open lattice work formed by spaced interconnected segments and curved sections extending between spaced bulkheads integral therewith that can be readily fastened to the base part to provide overhead support for the valve tappets. The lattice work has special expansion and contraction joints that connect into the bulkheads which mount the camshaft so that different rates of thermal expansion and contraction occurring between the lattice work and lower base part will cause deflection of the expansion joint and will not adversely effect the operation of the camshaft or the tappets carried by the bulkheads and lattice work.

    Abstract: The present invention discloses a structural oil pan for use with an internal combustion engine having a crankcase with short side walls of the type that generally do not extend below the center line of the crankcase. The oil pan has internal ribs which slidingly receive lower portions of the main bearing caps. The main bearing caps are fixed, relative to the oil pan with bolts passing through openings in the pan to threadingly engage corresponding openings in the bearing caps. Such an oil pan design allow the crankcase side walls, the crankshaft main bearing caps and the oil pan side walls to be structurally joined to resist vibration and noise generation. Weight savings are recognized by the oil pan of the present invention as the need for an engine block having extended side walls and increased weight is supplanted by a light weight, structurally rigid oil pan.
