FIELD: engines and pumps. ^ SUBSTANCE: invention is related to the field of machine building, namely, to piston internal combustion engines. Substance of invention consists in the fact that every engine cylinder is equipped by its screw ball mechanism that converts rectilinear reciprocal movements of pistons into shaft rotary motion. In screw ball mechanism all kinematic pairs are equipped with rolling bodies, i.e. frictional torque of rolling pairs is minimum. ^ EFFECT: higher reliability of engine, simplification of its design, higher efficiency factor. ^ 3 cl, 11 dwg, 2 tbl |
