2.7 biturbo

["Julio C Negron" <elprofe@isla.net>]

hi!
let's talk about camshaft control or variable timing valve on this Audi
biturbo.

The camshaft timing has been modified compared to the 2.8-litre V6 to meet
the demands of turbocharging technology....
Variable valve timing with an adjustment angle of 22º is here for the first
time in TURBOCHARGED ENGINES!!


Activation of the variable valve timing is dependent on engine load and
speed...
with this setting a 10% (approx.) is achieved at the bottom and top ends of
the engine speed range....
