An automotive reciprocating engine design is disclosed preferably including an extruded cylinder bore block with cylinder bores and a surrounding coolant passage extending from a top flat surface to a bottom flat surface; a cast, closed bottom, open top crankcase with vertical walls having flat upper surfaces; and a stamped metal mid-plate interposed in sealing relationship between the bottom surface of the cylinder block and the flat top surfaces of the crankcase. The crankcase contains bearing supports for a crankshaft and the mid-plate contains holes for connecting rods attached to pistons in the cylinder bores. The design facilitates low cost manufacture of strong, light weight components and easier assembly of the engine, and permits flexible manufacture of a family of engines with different displacements by substitution of a cylinder block of different length or of different bore diameter.

An engine block mold package includes a barrel crankcase core having a plurality of barrels on each of which a respective cylinder bore liner is disposed. Each cylinder bore liner includes an inside diameter that is tapered along at least a portion of its length to match a draft angle present on the barrels to permit removal of the barrel crankcase core from a core box in which it is formed.

Crankshaft bearing cap presenting on one of its faces a semi-cylindrical notch, formed by powder metallurgy with an iron powder blend molded by compaction and sintering, and partially infiltrated with Cu, being the area adjacent to the area around the notch, the one with highest Cu content. A method for manufacturing main bearing caps by infiltration of Cu including the steps of placing the molded cap so that the axis of the semi-cylindrical notch extends in a horizontal direction and the notch cavity is in the upwards position. Placing high Cu content tablets on the upper face of the cap and on the cylindrical arch and sintering of the cap and Cu tablets system.

An improved cutting tooth configuration in which, unlike the conventional, straight line tool pattern with its constant tool rise, each tooth is incrementally advanced relative to the prior tooth by an amount that progressively decreases. This accounts for the variations in reaction force on the cutting teeth caused by workpiece deflections, so that the net thickness of material removed by each cutting tooth remains relatively constant. Instability and variation in the cutting force are thereby avoided, and tool wear is decreased.

An engine cylinder block assembly for a V-type engine wherein inner walls of the cylinder banks define a relatively oil free valley which is closed by a rigid valley cover to provide additional stiffness to the inside walls of the blocks, thereby stiffening the block against vibration and bending. The valley cover also includes sealed pockets for enclosing knock sensors mounted upon upwardly extending bosses in the bottom of the valley to both protect the knock sensors and permit their removal without requiring removal of the valley cover from the engine cylinder block. Oil entrainment due to pulsing air flows between crank chambers of the engine are reduced by providing openings in the valley floor between the front and rear crank chambers of the engine while the adjacent inner crank chambers are separated from direct connection with the valley.

The disclosure reveals a computer vision technique to measure flank and crater wear of a single point cutting tool. This direct tool wear measurement method uses a microscope mounted camera to acquire an image of the tool. Special lighting of a face of the tool shows contrast of the wear region in the image. The image analysis is based on an interactive procedure utilizing a general purpose image processing system. A computer program calculates ten parameters to characterize flank and crater wear.
