VVL
Encyclopedia : V : VV : VVL : VVL
Nissan Ecology Oriented Variable Valve Lift and Timing (commonly known as VVL) is an automobile variable 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 camshaft lobes. It functions similarly to Honda's VTEC system.
One difference from Honda's VTEC system, is that NEO VVL engages the change of intake and exhaust cams independantly. On the SR20VE the intake camshaft is switched at 5000rpm, and the exhaust at 6500rpm.

Currently, this technology is only available in the Japanese Market. However, many Nissan enthuisiasts import this engine for swap.See also
