VVT-i (Variable Valve Timing with intelligence) |
 |
Toyota' s award-winning Variable Valve timing with intelligence
(VVT-i) technology utilises a sophisticated computer to vary the
air intake valve timing according to driving conditions and
engine load.
By adjusting the overlap time between the exhaust valve closing
and intake valve opening, the engine characteristics can be
changed to provide instant engine torque across the entire rev
range. This gives the best of both worlds: Powerful acceleration
and superior fuel economy. In addition, more complete fuel burn
at a higher combustion temperatures leads to fewer emissions. |
