ABSTRACT:
A device for changing compression of an internal combustion engine, wherein the internal combustion engine has a cylinder, a piston reciprocating in the cylinder, a crankshaft having a crank, and a connecting rod having a first end connected to the crank and a second end connected to the piston, includes an eccentric bushing resting with an inner cylindrical surface on the crank and with an eccentric outer cylindrical surface at the connecting rod so that by rotating the eccentric bushing relative to the connecting rod an effective length of the connecting rod is changed. The eccentric bushing has a least two locking recesses. A locking member is connected to the connecting rod and moveable in different directions into one or the other of the at least two locking recesses for locking the eccentric bushing in a first and second rotational position. In a first rotational position the effective length of the connecting rod is at a maximum and in a second rotational position the effective length of the connecting rod is at a minimum.
