Abstract: A composite piston for internal combustion engines is provided. The base structure of the piston is formed from a fiber-reinforced resin material. Covering the head portion of the base structure and integral therewith is a cap portion formed of a nonflammable material such as metal, metal alloys and ceramics. The cap and head portion of the piston have an outer diameter which is less than the outer diameter of the piston body by an amount sufficient to accommodate for the difference in the thermal coefficient of expansion of the material of the cap and the material of the base structure.

Abstract: Ceramic coatings prevent metal to metal contact between double acting pistons and cylinders. Cylinders and pistons operate in true cylindrical form. Ceramic coated cylinders are gradually brought to operating temperatures while temporary cutting pistons shape the coating to a true cylinder at operating temperature. Cylinders are formed true while cold and cylinders and heads are jacketed with high heat flow conductors so that the cylinders and cylinder heads have uniform operating temperature.

Abstract: A piston has a pair of support members extending away from the piston head offset from a piston ring portion, a piston rod being carried on a connecting rod which is clamped between the support members by a bolt. The bolt is loosely received in a bore in the connecting rod, the force between the piston and the piston rod being taken by a frictional force between the connecting rod and the support members to prevent a bending force being applied to the bolt.

Abstract: A production line for mechanically assembling pistons into cylinders of an internal combustion engine block and for automatically mounting the split bearing for each piston connecting rod to the crankshaft of the engine. At one end of the line, the engine block is laid on end with the piston cylinders extending horizontally. A magazine with a generally cylindrical sleeve in alignment with each cylinder bore in the engine is supplied with pistons complete with connecting rods. The connecting rods are positioned facing the top of the engine block. A split bearing end cap for each piston is placed in suitable holders on the sides of the magazine. At one station of the line, a ram automatically pushes one or two pistons into the engine block. A nesting receiver is positioned to receive the end of a connecting rod and guide the bearing end of the rod onto the crankshaft. Thereafter the bottom split bearing end cap is carried to the crankshaft for connection to the top end cap of the connecting rod. This procedure is repeated, as necessary, to fit the remaining pistons into the engine cylinders.

Abstract: A one piece piston connected to a connecting rod, for high speed four-stroke cycle internal combustion engines, in which the piston top has a centrally arranged spherical combustion chamber with a constricted opening while the piston is made of cast iron, preferably of tough cast iron, or spheroidal cast iron, or malleable cast iron, and while the piston skirt below the piston ring grooves has two flattened surfaces located opposite to each other and perpendicular to the axis of the piston bolt and parallel to the piston axis. The flat surfaces are located approximately along the same plane as the outer wall of the spherical combustion chamber while bearings for the piston bolt extend at least approximately from flat surface to flat surface and while the connecting rod is firmly shrunk onto the piston bolt.
