エンジン。 An eccentric that is inserted between the large end of the connecting rod of the piston and the crank pin of the crankshaft, and that makes the center line of the crank pin eccentric with respect to the center line of the large end of the connecting rod. a bushing, an internal gear provided integrally with the eccentric bushing, and an internal gear meshing with the internal gear at an inner circumferential portion so as to cause the eccentric bushing to revolve along the inner circumferential portion during rotation of the crankshaft. The crank pin has an engaging part that rotates around the center line of the crank pin, a rotating ring that is attached to a fixed part of the engine body so as to be rotatable by a predetermined angle, and a driving means that rotates the rotating ring. , the eccentric bushing is arranged along the radial direction of the crank pin.
A variable compression ratio engine characterized in that the divided body is assembled integrally with the crank pin.
