Editing VTEC (section)

=== Differences from other VTECs ===
Honda's advanced VTEC technology departs greatly from its previous incarnations by no longer relying on switching between two sets of lobes on a given [[camshaft]]. It instead uses a single [[Cam (mechanism)|cam lobe]] per valve, and two rocker arms per valve whereby the second rocker arm has a movable pivot point, thereby providing the varying cam lift. Advanced VTEC motors still use the now standard oil pressure controlled variable cam gear angle mechanism. With these two technologies combined Honda has developed an infinitely variable valve timing and lift system ("VVTL"). Previous versions of VTEC included only staged VVTL i.e. High-Low. With the introduction of i-VTEC the systems gained infinitely variable valve timing but still only staged lift i.e. High-Low. The "infinitely variable" portion of the A-VTEC is what makes it stand out as a serious evolutionary step in the world of VTEC.<ref>{{cite web |url=http://www.vtec.net/news/news-item?news_item_id=659664 |title = Temple of VTEC Rumors and News - A-VTEC Details Break Cover at USPTO; TOV Analyzes}}</ref>
