What is the meaning of VVT-i?

Variable Valve Timing-intelligent
Tokyo―TOYOTA MOTOR CORPORATION announced today the development of its new “Variable Valve Timing-intelligent” (VVT-i) technology, which increases performance and fuel economy. Engine development today necessitates both better fuel economy and advanced vehicle performance.

How does Toyota VVT-I engine work?

The system works by using a variable-speed head for the camshaft. This increases or decreases the speed of the camshaft in relation to the engine’s drive timing. That, in turn, changes the duration of the valve lifting to control intake and exhaust.
