The present invention relates, in particular, to a variable compression ratio (VCR) piston machine comprising a crankshaft, at least one connecting rod, which is rotatably mounted on the crankshaft, wherein the connecting rod has a small bearing eye and a large bearing eye, and wherein the connecting rod has a connecting rod shaft, further comprising a compression piston, which is arranged on the connecting rod, preferably a combustion chamber piston which can be adjusted by means, for example, of an eccentric or some other adjusting element and of an adjustment system, preferably an adjustment linkage, wherein the adjustment system is supported by means of at least one support piston, which can be moved in a support cylinder of the connecting rod. A proposal is furthermore made for a method in which an adjustment accomplished by external forces acting on the adjustment system is supplemented or improved by additional adjustment forces.
