Also called variable valve actuation (VVT), variable-cam timing and variable valve timing and lift electronic control (VTEC)

Engines with Variable Valve Timing & Lift Valves control the flow of air and fuel, into the cylinders and exhaust out of them. When and how long the valves open (timing) and how much the valves move (lift) both affect engine efficiency. Control is handled by the ECM and a variety of input sensors and switches that monitor every engine function, allowing the timing to adjust to your driving situation.

Optimum timing and lift settings are different for high and low engine speeds. Traditional designs, however, use fixed timing and lift settings, which are a compromise between the optimum for high and low speeds. VVT&L systems automatically alter timing and lift to the optimum settings for the engine speed.

Small technical advancements such as this, when added to the other small advancements can make a sizable difference in fuel mileage. As the need for fuel conservation increases, expect to see more changes that lead to better fuel economy.
