A.V.E.C it's a French acronym for "Air + Vortex = Economiseur Carburant" in english : "Air + Vortex = Fuel Saver"

The ratio is 1 by 1 ; that is to say the velocity of the input air become a rotational velocity of output air.

This module is placed on the air collector on engine (gasoline or diesel). He should be without electronic injection or turbocharger.

The air vortex enable a better combustion, faster penetration in cylinders by valves and faster degassing, so you have more torque and effectiveness.

You can reach between 10 and 25% fuel saving.
