Method and system for operating a fuel vapor capture system of an air intake system of an internal combustion engine

An air intake system for an internal combustion engine, comprising:

• a fuel vapor capture system disposed in an interior portion of the air intake system, the fuel vapor capture system including a Metal Organic Framework (MOF) material, the MOF material configured to adsorb and desorb hydrocarbon fuel vapor;
• a controllable device integrated into the fuel vapor capture system;
• a controller, operatively connected to the controllable device;
• the controller including an instruction set, the instruction set being executable to:
• activate the controllable device in response to a command to actively purge the fuel vapor capture system,
• determine an intake air purge flowrate and a total purge mass based upon the intake air purge flowrate, and
• deactivate the controllable device when the total purge mass is greater than a purge mass threshold.

A method for operating an on-vehicle fuel vapor capture system arranged in an air intake system of an internal combustion engine, the fuel vapor capture system arranged to capture fuel vapors from the internal combustion engine, wherein the fuel vapor capture system is composed of a flexible Metal Organic Framework (MOF) material that is coupled to a controllable device, the method comprising:

• monitoring operation of the internal combustion engine;
• activating the controllable device and determining an activation parameter for the controllable device;
• determining an intake air purge flowrate and a total purge mass based upon the intake air purge flowrate;
• and
• deactivating the controllable device when the total purge mass is greater than a threshold.
