Variable valve timing

In internal combustion engines, variable valve timing , also known as Variable valve actuation , is a generalized term used to describe any mechanism or method that can alter the shape or timing of a valve lift event within an internal combustion engine...

 technology developed by Nissan. N-VCT was first introduced in 1987 on the VG30DE and VG20DET engine. N-VCT varies the timing of the valves by rotating the cam shaft(s); valve lift and duration are NOT altered. The system is implemented with an electric solenoid which is controlled by the cars ECU. Some Nissan engines only have N-VCT on the inlet cam (such as the RB25DE/DET) while others have it on both the inlet and exhaust cams.
