Nissan Motor Company, has what is called Nissan Ecology Orientated Variable
Valve Lift and Timing. The Neo VVL engine was developed by Nissan around
1997. It saw limited release on some models. This in essence is a system
similar to the Honda VTEC valve lift system, but is also has variable valve
timing. This means that on a given rotational range, the engine will change
the lift and timing, on the intake and Exhaust cam independently. The NEO VVL engine
has a camshaft with two different cam lobe profiles. When one cam profile
is no longer needed or after 5000 RPM, the lift profile changes, and allows
the engine to keep putting out power all the way to the redline. Neo VVL
engines can generally rev to around 8200 RPM in stock form. This in effect
has the best of both worlds, a great idle response and high RPM power.
The Neo VVL engine changes the cam profiles independently. The Intake cam
changes first, and then the Exhaust
camshaft thereafter. Other manufactures, like Honda's V-Tec and Toyota's
VVTi switch both cams together. The end result is greater power generation
on the smooth side.
The Nissan Neo VVL uses two separate camshaft profiles. One profile works
best at low RPMs, while the other is meant for higher engine revolutions.
It also uses 3 activation stages. The low and high RPM profiles, are
effected by means of a ...

Road Race Nissan Sentra B13 SR20VE First tests @ Ponce Solo Uno
This is my first time on a road course and still very much to learn since I
come from a Drag Racing Background only...but the car is running good a few
more adjustments and changes and it should run very well and I will keep
practicing until I get better. so this is just a start much more to come so
stay tuned... :)
