Nissan Ecology Orientated Varable Valve Lift and Timing (commonly known as VVL) is an automobilevariable valve timing technology developed by Nissan. VVL varies the timing, duration, and lift of valves by using hydraulic pressure switch between two different sets of camshaftlobes. It functions similarly to Honda's VTEC system.
