Abstract: An internal-combustion engine comprised of a cylinder with at least one piston which is moving to and fro in it, and a piston rod (6), which transforms the piston's movement to rotary motion in a crank shaft (9), and including equipment for a forcible stabilization of the piston axle. Each small end of the piston rods has an additional part (6g) at its right side, to produce an additional torsional moment with the aid of inertial forces. This part is characterized by its optimized form; the piston rod's big end (6f) includes the additional parts (6m), (6n), also at its right side; In this way, the force vectors and the torsional moment of the motor are optimized due to the effect of the inertial forces and the mass of the entire piston rod may be used to increase the inertial forces, which results in a considerable improvement of the economic and ecological properties of internal-combustion engines and other piston engines.
