I know what V-TEC is but exactly how does it work? Does the cam have two sets of lobs on it? Please describe for me. THANKS.

 

Yes, there is a larger set of labes that the carswitches to at a designated RPM. Thats not it though, the ECu switches fuel maps and everything too


One of the main reasons these cars can rev so well. A low cam profile for idle and then switch to a very agressive cam. The best of both worlds.

Is there a certain RPM that the engine makes the changes? For example at 4k does the engine go from economy to high output? Thanks

 

Also is there a way that your VTEC can kick in at different times? My friends civic kicks in earlier than mine... is mine broken?

 

different engines kick in at different times, and yes, its at a certain rpm. but you dont necessarily want it to kick in at too much of a different point. the smaller lobes make more power in the lower rpms than the bigger ones do, and vice versa. so if it switches over too early, you will lose power, and if it changes over too late, same thing. its usually pretty close to where it should be from the factory.

 

Barb, yours isn't broken......your VTEC is only taking it's time so that it can enjoy your driving longer!
