Beschreibung
Zusammenfassung:	A variable compression ratio (VCR) internal combustion engine having a compression stroke and an expansion stroke includes an engine block defining a cylinder and a cylinder head mounted to the engine block and defining at least a part of a combustion chamber. The VCR engine also includes a reciprocating piston arranged inside the cylinder and configured to compress a mixture of air and fuel and receive a combustion force, wherein the compression stroke of the piston defines a compression ratio of the engine. The VCR engine additionally includes a six-bar linkage mechanism configured to operatively connect the piston to the engine block, articulate on seven distinct parallel axes, decouple the compression stroke from the expansion stroke, and continuously and selectively vary the compression stroke of the piston and the compression ratio of the engine.
