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.

Abstract:

An air intake system for an internal combustion engine is described, and includes a vapor capture element disposed in an interior portion of an air intake system. The vapor capture element includes a flexible Metal Organic Framework (MOF) material, wherein the flexible MOF material is reversibly controllable to a first state and to a second state in response to a control stimulus. The flexible MOF material is configured to adsorb hydrocarbon vapor when controlled to the first state and configured to desorb the hydrocarbon vapor when controlled to the second state.
