Described herein is a control system for controlling the emissions of fuel vapors from a vehicle comprising a first adsorption system and a second adsorption system. The first adsorption system is formed by a canister preferably filled with activated carbons having a grain size greater than 4 mm. The second adsorption system is made up of a tubular housing, which has a ratio between the equivalent diameter D and the axial height H of between 1:2.5 and 1:4.5 and is filled with activated carbons having a grain size greater than 4 mm.
