Patent number: 8534054Abstract: According to one aspect of the present invention, a liquid reductant tank for supplying liquid reductant to a selective catalytic reduction system is disclosed. The tank includes a tank cavity for holding a liquid reductant and being at least partially defined by one or more side walls; a liquid reductant supply line at least partially situated within the tank cavity and for communicating liquid reductant from the tank cavity to outside of the tank cavity; and a heating element situated at least partially within the liquid reductant supply line and for thawing frozen reductant situated within the supply line during cold start conditions to obtain liquid reductant for use in a selective catalytic reduction system.Type: GrantFiled: February 1, 2011Date of Patent: September 17, 2013Assignee: Ford Global Technologies, LLCInventors: David Cook, Furqan Zafar Shaikh, Michael Levin, David Furedy, Evan Kent Dawson, Daniel Kabat, Jeremy Keller

Patent number: 7938107Abstract: A flow control valve, comprising a flow controlling valve configured to deflect from a generally planar posture to an increasingly nonplanar posture responsive to a relative increase in pressure difference and flow across the valve element; and a support element including a support structure supporting the valve element in its undeflected state; at least a first contact surface recessed from the support structure and configured to engage the valve element only when the valve element is deflected; and a flow passage wherein an effective flow-through volume through the at least one opening and the flow passage decreases as deflection of the valve element increases.Type: GrantFiled: April 30, 2008Date of Patent: May 10, 2011Assignees: Ford Global Technologies, LLC, Massachusetts Institute of TechnologyInventors: David C. Freeman, Alexander H. Slocum, Daniel Kabat

Patent number: 7370645Abstract: A flow control valve is provided. According to one aspect of this disclosure, the flow control valve includes a valve element and a support element. The valve element is configured to deflect responsive to a change in pressure difference across the valve element. The support element cooperates with the valve element to present an effective flow-through area that changes as the valve element deflects. The amount of relative engagement between the valve element and the support element changes as the valve element deflects. External vibration causes the valve element to vibrate to reduce stiction or ice buildup.Type: GrantFiled: May 24, 2005Date of Patent: May 13, 2008Assignee: Ford Global Technologies, LLCInventors: David C. Freeman, Alexander H. Slocum, Daniel Kabat

Publication number: 20070277505Abstract: A system and method for controlling venting of an on-board vehicle emissions treatment substance storage and distribution system that selectively dispenses an emissions treatment substance from a storage tank on the vehicle to an exhaust system of the vehicle include selectively coupling the storage tank to the exhaust system when pressure in the storage tank exceeds a predetermined pressure associated with the exhaust system. The invention may also include selectively coupling the storage tank to atmosphere when a pressure differential between the storage tank and atmosphere exceeds a predetermined pressure differential.Type: ApplicationFiled: May 30, 2006Publication date: December 6, 2007Applicant: FORD GLOBAL TECHNOLOGIES, LLCInventors: Kent Dawson, Furqan Shaikh, Michael Levin, David Cook, Daniel Kabat
