Abstract: A vehicle system having an internal combustion engine and evaporative emission system including a canister is described, wherein canister includes a chamber having a flexible Metal Organic Framework (MOF) material disposed therein. A controllable device is coupled to the flexible MOF material, and a controller is operatively connected to the controllable device and the purge valve. The controller includes an instruction set that is executable to activate the controllable device and control the purge valve to an open state in response to a command to purge the canister, determine an activation parameter for the controllable device, determine a purge flow, integrate the purge flow to determine a total purge mass, and deactivate the controllable device when the total purge mass is greater than a threshold.

Abstract: Based on a desired average number of activated cylinders per sub-period of a predetermined period including P sub-periods, a cylinder control module selects one of N predetermined cylinder activation/deactivation patterns. The selected cylinder activation/deactivation pattern corresponds to Q activated cylinders per sub-period, Q is an integer between zero and a total number of cylinders of an engine, inclusive, P is an integer greater than one, and the desired average number of active cylinders is a number between zero and the total number of cylinders of the engine. The cylinder control module also determines an adjusted cylinder activation/deactivation pattern based on the selected predetermined cylinder activation/deactivation pattern, generates a desired cylinder activation/deactivation pattern for the predetermined period using the selected predetermined cylinder activation/deactivation pattern during a first number of the P sub-periods and using the adjusted cylinder activation/deactivation pattern during a second number of the P sub-periods.

Abstract: An engine control system for a vehicle includes an exhaust gas recirculation (EGR) rate-estimation module and a control module. The EGR rate-estimation module receives a first signal indicating a first relative humidity of a flow of air and a second signal indicating a second relative humidity of a mixed flow of air and exhaust gas. The EGR rate-estimation module determines an estimated EGR rate based on the first relative humidity and the second relative humidity, wherein the estimated EGR rate corresponds to a flow rate of a flow of exhaust gas to an engine. The control module selectively adjusts an engine operating parameter based on the estimated EGR rate.

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.

Abstract: A fuel vapor control system for a vehicle includes a fuel vapor canister that traps fuel vapor from a fuel tank of the vehicle. A purge valve opens to allow fuel vapor flow to an intake system of an engine and closes to prevent fuel vapor flow to the intake system of the engine. An electrical pump pumps fuel vapor from the fuel vapor canister to the purge valve. A vent valve allows fresh air flow to the vapor canister when the vent valve is open and prevents fresh air flow to the vapor canister when the vent valve is closed. A purge control module controls a speed of the electrical pump, opening of the purge valve, and opening of the vent valve.

Abstract: A fuel vapor system for a vehicle includes a fuel vapor canister that traps fuel vapor from a fuel tank of the vehicle. A purge valve opens to allow fuel vapor flow to an intake system of an engine and closes to prevent fuel vapor flow to the intake system of the engine. An electrical pump pumps fuel vapor from the fuel vapor canister to the purge valve. A diagnostic module (a) selectively diagnoses a fault in the fuel vapor system based on at least one of: (i) a speed of the electrical pump measured using a pump speed sensor; and (ii) a pressure at a location between the electrical pump and the purge valve, and (b) illuminates a malfunction indicator lamp (MIL) within a passenger cabin of the vehicle when the fault is diagnosed.
