Patent number: 10287938Abstract: A method for a vehicle comprises responsive to installation of a new exhaust particulate filter, doping fuel with an ash-producing additive, and combusting the doped fuel to produce ash, wherein the ash deposits as an ash coating on the new exhaust particulate filter. In this way, a filtration efficiency of an exhaust particulate filter can be increased quickly as compared to a filter with no deposited ash coating, inexpensively as compared to conventional methods using membranes, and with a lower back pressure drop as compared to conventional methods.Type: GrantFiled: June 15, 2015Date of Patent: May 14, 2019Assignee: Ford Global Technologies, LLCInventors: James Robert Warner, Timothy Brian Chanko, William Charles Ruona, Giovanni Cavataio, Douglas Allen Dobson

Patent number: 9726058Abstract: Systems and methods are described for coordinating the regeneration of a gasoline particulate filter to a time duration when engine output falls below a predetermined load threshold selected to indicate a low power state of the engine. In one particular example, the engine is configured to adjust engine operations to regenerate the particulate filter responsive to engine output falling below a predetermined low power threshold, the regeneration further based on an estimated duration that the output falls continuously below the low power threshold. The system and methods described advantageously allow for either full or partial regeneration events to be performed based on the estimated duration of the engine output below the low power threshold.Type: GrantFiled: January 8, 2015Date of Patent: August 8, 2017Assignee: Ford Global Technologies, LLCInventors: Timothy Brian Chanko, James Robert Warner, Douglas Allen Dobson, Devesh Upadhyay

Patent number: 9650930Abstract: Various methods are provided for operating an emission control device. In one example, a method for an emission control device including a catalyst and a filter comprises passively regenerating the filter, and adjusting, via a controller, a duration of active regeneration of the filter based on an oxygen storage capacity of the emission control device.Type: GrantFiled: January 12, 2015Date of Patent: May 16, 2017Assignee: Ford Global Technologies, LLCInventors: Christine Kay Lambert, Douglas Allen Dobson, James Robert Warner, James David Pakko, Jeffrey Scott Hepburn

Patent number: 9630146Abstract: A particulate filter for use in a vehicle engine exhaust is provided which includes a catalyst containing a mixture of nickel and copper. The catalyst is impregnated into the filter substrate, which is non-reactive with nickel and copper. When used in a vehicle exhaust gas treatment system, the catalyst on the filter improves soot burn-off at low temperatures, provides improved efficiency in reducing CO and NOx emissions over the use of conventional three-way-catalyst washcoats, and provides enhanced oxygen storage capacity (OSC) and water-gas-shift (WGS) functions.Type: GrantFiled: June 3, 2013Date of Patent: April 25, 2017Assignee: Ford Global Technologies, LLCInventors: James Robert Warner, Douglas Allen Dobson, Hungwen Jen, Giovanni Cavataio

Patent number: 9523303Abstract: Methods and systems are provided for determining soot stored in a particulate filter and regenerating the particulate filter. In one example, a method provides for operating oxygen sensors in a way that allows water in exhaust gases to be determined. The water in exhaust gases may be a basis for determining an amount of soot stored in a particulate filter.Type: GrantFiled: January 29, 2015Date of Patent: December 20, 2016Assignee: Ford Global Technologies, LLCInventors: Gopichandra Surnilla, Manish Sharma, James Robert Warner

Patent number: 9339800Abstract: A method for treating engine exhaust. The method includes contacting an NOx exhaust with an upstream catalyst material coated onto a substrate and including copper or iron loaded in a first zeolite at an upstream loading of 0 to 3.5 g/l to convert the NOx exhaust in a first temperature range of 150° C. to 500° C. to a first NOx converted exhaust. The method further includes contacting the first NOx converted exhaust with a downstream catalyst material coated onto the substrate downstream of the upstream catalyst material and including copper or iron loaded in a second zeolite at a downstream loading of 1.5 to 9.5 g/l to convert the first NOx converted exhaust in a second temperature range of 450° C. to 700° C.Type: GrantFiled: July 22, 2015Date of Patent: May 17, 2016Assignee: Ford Global Technologies, LLCInventors: Giovanni Cavataio, Hungwen Jen, James Robert Warner, James W.
