How does VVTi technology work?

Analyzing Driving Conditions

VVTi technology relies on an electronic control unit that monitors driving conditions such as vehicle speed, engine RPM, and the amount of air entering the engine.

Adjusting Valve Timing

Based on the data collected by the control unit, the timing of the valve openings and closings is adjusted to achieve optimal performance.

• At low speeds, the valve timing is adjusted to reduce fuel consumption.

• At high speeds, the timing is adjusted to increase the amount of air entering the engine and improve horsepower.
