V-TEC

Variable valve Timing and Electronic lift Control. This engine design uses two sets of cams, one for low RPMs and one for high RPMs. When in higher RPMS, the longer lobs are used to open the intake for longer, as it is known that at higher RPMs a better engine response is given, but at lower RPMs it is counter productive, thus the other lower RPM set. The high RPM set is engaged by the computer system, in effect changing the valve timing on the fly.
