Continuous Variable Valve Timing Control System (CVVTCS) is an automobile variable valve timing technology developed by Nissan. It is also used in a twin CVTC configuration on engines like the Nissan Juke's MR16DDT engine. CVVTCS is the successor to Nissan's earlier valve timing implementation NVCS.
