Valvematic on NAV1 performance enhancer VVT-i
Valvematic is not a new system, this technology as a complement VVT-i work in operating the valves. So in Valvematic engines remain VVT-i unit that regulates intake valve opening time and waste.
Valvematic will help to regulate how much optimization of valve opening, of course, adapted to the needs of the machine. Whereas in conventional engines, though the timing is set by VVT-i, while the size of the valve opening is fixed.
Therefore, these two technologies have to work together. Later, the valve opening timing will be governed by the Dual VVT-i, is governed by the size of the valve opening Valvematic. Then, if the valve to the throttle?
The valve will only function as a silencer of the intake. So Valvematic tech machines will be much smoother. Just imagine, even if the throttle is opened, but since the machine only needs less fuel, fuel flow entering certainly set again by opening the valve.
As a result, fuel consumption can be more efficient because the incoming gas flow very accurately to the needs of the machine, plus the exhaust emissions will be much cleaner. So, not only the pursuit of efficient engines, engine output will remain powerful with faster response.
Technology created Valvematic Toyota continued opposition from competitors, Honda. Where, Honda also designed this system as technology AVTEC (Advanced VTEC). Even Honda adds inlet length can be variable in this AVTEC.
