VVT-i, or Variable Valve Timing with intelligence, is an automobile variable valve timing technology developed by Toyota. The Toyota VVT-i system replaces the Toyota VVT offered starting in 1991 on the 5-valve per cylinder 4A-GE engine. The VVT system is a 2-stage hydraulically controlled cam phasing system.
shortening the valve duration on lower RPMs or when engine requires less power, and; increasing the valve time to let more fuel in when more power is required. Typically, as aforementioned, only the intake valves have variable timing, but in a dual VVT-i system, both the intake and exhaust valves have variable timing. The variable timing on ...

VVT-i, or Variable Valve Timing with intelligence, is an automobile variable valve timing technology developed by Toyota, similar to the i-VTEC technology by Honda. The Toyota VVT-i system replaces the Toyota VVT offered starting in 1991 on the 4A-GE 20-Valve engine.
Dual VVT-i. Similar to VVT-i, Dual VVT-i adds in control of the exhaust camshaft to the VVT-i's control of intake valves. This is found in the latest-generation V6 engines, starting with the 2GRFE in the 2005 Avalon in the U.S. It is now the most common VVT system in use by Toyota, appearing in most of the LR, UR, GR, AR and ZR engine families.
