A crankshaft system for internal combustion engines built for record rotational or racing speeds and power because of a pure sinus piston motion, low friction and small size. The system is based on hypocycloid movement, but with small diameter of (eccentric) circular cam driving one- or double-sided piston. The circular cam performs flat motion: uniform rotation in its own plane plus a straight-line sinusoidal reciprocal movement. It substitutes a connecting rad and drives the piston directly. A piston skirt and wrist pin are absent, the piston itself may be double-sided (boxer), in one piece, and light. Self compensating mechanism maintains high precision of sinus piston motion over the life of the system, compensating for wear and thermal dilation. Full balancing even of one-cylinder engine may be achieved. An engine 90° V2 is inherently fully balanced. Intrinsic lack of forces acting on cylinder walls means high mechanical efficiency - cylinders are subjected only to the piston's rings friction. This makes the system easy to cool, or allows for more power. Very suitable for all supercharged engines and Direct Injection Diesel. Suitable for one-cylinder engines, V2 (especially 90°), V, boxer, X, star or in -line.
