A (CVVT) system optimizes intake valve timing by controlling intake valve open and close timing. The CVVT system improves fuel efficiency and reduces NOx emissions at all levels of engine speed, vehicle speed, and engine load by EGR effect because of valve over-lap optimization. The CVVT modifies the combustion chamber, intake manifold, camshaft and ignition system form the basic control system.

The following schematic depicts the (CVVT) Wiring Diagram.
