Patent number: 9739223Abstract: Methods and systems are provided for an emission control device for an engine system including a gasoline particulate filter (GPF) and bypass passage for the GPF. In one example, the system may include a converging cone to direct exhaust flow through a central bypass passage, housing a valve, which originates upstream of the GPF and eventually passes through the center of it (thereby bypassing the GPF). In another example exhaust flow may travel through outer passages, coupled between the converging cone and GPF and spaced around the central bypass passage, to travel to the GPF.Type: GrantFiled: November 18, 2015Date of Patent: August 22, 2017Assignee: Ford Global Technologies, LLCInventors: James David Pakko, Mark Kreger, Jimmy Theis

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: 9194311Abstract: Methods and systems are provided for heating a catalyst during engine cold-start conditions. One example embodiment uses positive valve overlap to drive a boosted blow-through airflow through the cylinders of an engine. Fuel is injected with the blow-through airflow during the valve overlap, and also injected into engine cylinders outside the valve overlap. The catalyst is heated by the resulting exothermic reaction of the blow-through airflow with the combustion products and the injected fuel in the exhaust manifold.Type: GrantFiled: September 11, 2012Date of Patent: November 24, 2015Assignee: Ford Global Technologies, LLCInventors: Michael Daniel Shane, James David Pakko, Paul M. Laing

Patent number: 5974790Abstract: A method for restoring exhaust purifying capability of a sulfur contaminated catalytic converter of an internal combustion engine. Catalytic converter efficiency is measured with a first exhaust gas oxygen sensor positioned upstream of the catalytic converter and a second exhaust gas oxygen sensor positioned downstream of the catalytic converter. When catalytic converter efficiency falls below a desired level, catalytic converter temperature is elevated and the engine is operated to produce a rich exhaust gas mixture to reduce the sulfur contamination. Then, to further reduce the sulfur contamination, the engine is operated to produce a lean exhaust mixture.Type: GrantFiled: March 5, 1998Date of Patent: November 2, 1999Assignee: Ford Global Technologies, Inc.Inventors: Andrew Anthony Adamczyk, Arthur E Kolasa, James David Pakko
