International Classification:

B65D 45/00

US Classification:

220315

Abstract:

A fuel cap for a filler neck on a fuel tank includes a cap body having threads for engaging the filler neck when the fuel cap is installed on the filler neck and a cap handle rotatably mounted on the cap body. A clutch acts between the cap handle and the cap body to permit the cap handle to rotate freely on the cap body when the clutch is disengaged. When the clutch is engaged, rotation of the cap handle will rotate the cap body so that the user can remove the fuel cap from the filler neck to refuel the vehicle. A pressure-sensing diaphragm disengages the clutch when the pressure differential between the fuel vapor pressure and the atmospheric pressure exceeds a predetermined threshold and engages the clutch when the pressure differential between the fuel vapor pressure and the atmospheric pressure is less than the predetermined threshold.

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.

International Classification:

F02M 25/08
B01D 53/04

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.

B01D 46/00
B01J 20/22

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.

Inventors:

- Detroit MI, US
Timothy E. McCarthy - Grand Blanc MI, US

International Classification:

F02D 41/00
F02M 25/08

Abstract:

An exemplary system for monitoring and controlling evaporative emissions for a vehicle includes a first fuel vapor adsorption canister, a second fuel vapor adsorption canister, a first passage from the fuel supply to the first canister, a second passage from the first canister to the canister, the second passage including a first valve selectively actuatable from a first position to a second position, a third passage from the first and second canisters for venting the first and second canisters, a fourth passage connecting the second canister to the third passage, and a controller electrically connected to the first valve. Fuel vapor is routed to the first canister when a first condition is not satisfied and fuel vapor is routed to the second canister when the first condition is satisfied.
