Ever-tightening emissions requirements, teamed with consumers' lust for today's high horsepower numbers, have led to some creative valve timing and lift schemes. Infiniti's G37 will be pack some interesting tech underhood when it debuts at the upcoming New York International Auto Show. There are actually two new developments working in conjunction to give independent control over valve timing and lift. Nissan has dubbed the control technologies Variable Valve Event and Lift and Continuous Valve Timing control, or VVEL and C-VTC, respectively. VVEL uses a clever arrangement of links to actuate the valves, and moves the fulcrum for the links via a seperate shaft actuated by a DC motor. By moving the fulcrum, the valve lift is varied.
