Development of the Variable Valve Timing and Lift (VTEC) Engine for the Honda NSX 910008
The Honda variable valve timing and lift electronic control system (VTEC) is incorporated in the engine of the NSX sports car that is scheduled for sales in Europe this year.
In the process of advancement of Honda's engine technology, VTEC was developed for much higher output and higher efficiency.
This is actually the first system in the world that can simultaneously switch the timing and lift of the intake and exhaust valves. This system has made improvements in maximum output at high rpm, and also improved the low rpm range, such as idling stability and starting capability.
