Abstract
The concepts described herein provide for a system, apparatus and/or method for fuel vapor capture on-vehicle for evaporative emission control. This includes a device for capturing fuel vapor on-vehicle that includes a canister device having a first port that is fluidly coupled to a head space portion of a fuel tank. The canister device defines a chamber that is fluidly coupled in series between the first port and a second port. A first Metal Organic Framework (MOF) material is disposed in the chamber to adsorb fuel vapor constituents.
