ABSTRACT:
A variable compression ratio rotating engine comprises a containing cylinder forming variable volume chambers, defined by the cylinder inner wall and piston side walls, the cross-section of which has substantially the shape of a circle sector. During the operation of the engine, the pistons are rotated with an uneven circular motion, by a mechanism including a crank, having an eccentric axis with respect to that of the containing cylinder, and small coupling rods coupling the arms of the crank and the end portions of small shafts passing through the pistons, the compression ratio being changed by means of a further mechanism able of changing the eccentricity value of the crank axis with respect to the cylinder axis.
