iVTEC How it Works -EricTheCarGuy

iVTEC How it Works is a long standing requested video. Back with I did the video on the VTEC explanation I was asked about doing a video on iVTEC which is slightly different than VTEC. First you need to understand the basic operation of the cam shaft, once you have that, and you know a little about how that cam shaft effects performance, you can then begin to understand how iVTEC works. In essence, as far as the Honda system is concerned, it varies the cam 'timing' to optimize performance and fuel economy. Many companies employ similar systems to this but they may perform the operation differently. This video focuses on the Honda iVTEC system.

That said, you may notice that the VTEC system on this K series is a little different in that instead of having a cam with a higher lift and duration, it switches between 1 and 2 valves on the intake side. So when VTEC engages on this engine it actually activates another valve in the cylinder instead of changing lift and duration. It still alters cam timing via the iVTEC system however. Once again, to optimize power output and fuel economy.

Either way, I hope this video helps with your understanding of camshafts, cam timing, lift, duration, VTEC, and iVTEC systems.

Thanks for watching.
