FIELD: mechanical engineering; frame or crankcase of engines of machines or apparatuses; frames which serve as bases of piston engines or machines for placing crankshaft. SUBSTANCE: method comes to connecting two-stroke internal combustion engine and connecting rod-and-crank mechanism into common unit in one guide base tube by means of flexible coupling in form of spring, axial attachment of internal combustion engine for turning on end face of engine tube and fastening of crankshaft on one frame by means of bearings, delivery of compressed air into friction zone through hole in connecting rod. EFFECT: simplified design of frame, increased speed of rotation. 2 dwg
