Piston motion in the conventional mechanism is essentially asymmetrical, with rapid motion occurring at top dead center. That unbalance deteriorates engine vibration in the case of conventional 4-cylinder engines.
With the multilink VCR mechanism, the piston's reciprocal action achieves ideal simple harmonic motion, resolving the unbalance. This enable low vibration property of in-line 4 cylinder engine close to that of V type 6 cylinder engines.
