Abstract: A four-stroke internal combustion engine including variable compression ratio comprises a crankcase including a crankshaft having a crankpin and being supported by the crankcase and rotatable with respect thereto about a crankshaft axis, a connecting rod including a big end and a small end, a crank member being rotatably mounted on the crankpin, and comprising at least a bearing portion which is eccentrically disposed with respect to the crankpin, a crank member drive system for rotating the crank member at a rotation frequency with respect to the crankcase which is half of that of the crankshaft, and a control system for operating the engine with repetitive cycles, wherein the compression ratio in the compression stroke is changed. The control system is configured to interrupt the repetitive cycles by rotating the crankshaft an additional single revolution between two successive combustion strokes for switching between a high and low compression ratio.

Abstract: An engine comprises a crankcase and a crankshaft. The crankshaft has a central main portion, a crankpin and a crankshaft web. A crank member is rotatably and eccentrically mounted on the crankpin. An external crank member gear meshes with an external drive shaft gear. A driven portion of the drive shaft is located at a side of the crankshaft web which is opposite to its side where the crankpin is located and is drivably coupled via a first transmission to an intermediate member which is rotatably mounted to the crankshaft. The intermediate member is drivably coupled to a control shaft portion of a control shaft via a second transmission which control shaft portion is located at axial distance of the driven portion of the drive shaft and the control shaft is rotatable at a fixed rotational position with respect to the crankcase under operating conditions at fixed compression ratio.

Abstract: A heat engine includes a system for varying the compression ratio of the engine. The compression ratio varying system comprises: at least one eccentric part rotatably mounted on a crank pin. The eccentric part has an eccentric outer face that co-operates with one end of a rod, as well as at least one ring gear. A device for controlling the angular position of the eccentric part, includes an actuating pinion mounted on an actuating shaft. The control device also comprises at least one stepped intermediate pinion having at least first and second steps each formed by a pinion, the pinion of the first step meshing with the actuating pinion and the pinion of the second step meshing with the gear of the eccentric part.

Abstract: A four-stroke internal combustion engine with variable compression ratio, comprises a crankcase, a crankshaft, a connecting rod having a big end and a small end. A piston is rotatably connected to the small end. A crank member rotatably mounted on the crankpin has a bearing portion which is eccentrically disposed with respect to the crankpin, wherein the bearing portion has an outer circumferential wall including a location of maximum eccentricity (P) which bears the big end of the connecting rod such that the connecting rod is rotatably mounted on the bearing portion of the crank member via the big end. Under operating conditions at or close to top dead center of the piston the angle between the connecting rod plane and the piston plane changes from a pre-angle before top dead center to a post-angle after top dead center.
