Abstract
An apparatus for changing the compression in a cylinder of a piston engine is provided that includes an eccentric for eccentrically mounting the one end of the piston rod to the piston, an eccentric swing component secured to the eccentric, and a linkage assembly for controlling the swing movement of the eccentric swing component to effect a corresponding change in the compression in the cylinder. The linkage assembly includes a position coupling for guiding the eccentric swing component to swing through a predetermined swing movement during stroke movement of the piston. A guide assembly guides the eccentric swing component or the position coupling along a predetermined path during its respective movement during a piston stroke.
