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.
