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: 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: The concepts described herein provide for a method, apparatus and system to monitor and control a fuel vapor capture system that is disposed in an air intake system of an internal combustion engine for evaporative emission control. This includes an air intake system for an internal combustion engine that includes 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 that is configured to adsorb and desorb hydrocarbon vapor and a controllable device that is integrated into the fuel vapor capture system. In one embodiment, the MOF material is a flexible MOF material.

Abstract: A lubrication system in a machine includes a sump to collect a bulk portion of lubricant and a pump adapted to circulate the lubricant from the sump through a lubricant line to an area of the machine for lubrication. The lubrication system also includes an oil filter disposed along the lubrication line adapted to filer the lubricant flowing through the lubricant line. The lubrication further includes an additive fixture in fluid flow communication with the oil filter adapted to house at least one additive material section and distribute the additive material in a lubrication flow circulation.

Abstract: A lubrication system for a machine includes a sump to collect a bulk portion of a fluid lubricant and a pump adapted to circulate the lubricant from the sump through a lubricant line to a lubrication target area of the machine. The lubrication system also includes a dip stick defining a first end outside of the machine, a second end immersed in the bulk portion of lubricant, and a lubricant level indicator between the first end and the second end. The lubrication system further includes an additive fixture coupled to the second end of the dip stick. The additive fixture includes at least one additive material section adapted to dissolve in the lubricant to distribute an additive chemical in lubricant circulating through the machine.
