Nissan VVEL - Variable Valve Event and Lift (VQ37VHR)

Just thought I'd post up some new Nissan technology in the Nissan section since there is never any action in here.

A rocker arm and two types of links close the intake-valves by transferring the rotational movement of a drive shaft with an eccentric cam to the output cam.

The movement of the output cam can be varied by rotating the control shaft within the DC motor and changing the fulcrums of the links. This makes a continuous adjustment of the valve lift amount possible.

While conventional engines control air intake using a throttle valve, VVEL-equipped engines do this directly at the intake valves, continuously controlling their valve events and lifts. C-VTC and VVEL together control the valve phases and its valve events and lifts, allowing free-control of the valve timing and lift. This results in more efficient airflow through the cylinder and significantly improves responsiveness, optimizing the balance between power and environmental performance.

Badass indeed. There is an article on Freshalloy about the new G35 coupe that will be using this engine. I remember reading that possibly some of the turbo technology from the new GTR may trickle down eventually into the G35.

impressive technology, do you have larger versions of the pics?

Nope sorry that's the best I got...
