Patent number: 11015539Abstract: Methods and systems are provided for identifying when an exhaust valve of an engine cylinder is not functioning as desired while the engine is being operated to raise a temperature of an exhaust system emissions control device, and in turn taking mitigating action. Thus, in one example a method comprises adjusting an amount of fuel that is provided to each of a plurality of cylinders of an engine during an exhaust stroke of the engine in response to an indication of degraded combustion stemming from a cylinder of the engine. In this way, the engine may continue to be operated to raise the temperature of the exhaust system emissions control device, while mitigating the issue of the degraded combustion.Type: GrantFiled: September 30, 2019Date of Patent: May 25, 2021Assignee: Ford Global Technologies, LLCInventors: Brien Lloyd Fulton, Frank M. Korpics, Aaron John Oakley, Kirk Andrew Parrish, Sanket Anil Gujarathi, Nicholas Sovis, Dayton Brenner, Joseph Goode, Nicholas John Vella

Patent number: 9441524Abstract: Various systems and methods are described for an engine system with an exhaust gas treatment system including a particulate filter. In one example method, accumulated hydrocarbons are removed from the exhaust gas treatment system by increasing an exhaust gas temperature to a first temperature responsive to a particulate filter regeneration request during extended cold idle operation. After a predetermined duration, the exhaust gas temperature is increased to a second, higher temperature to regenerate the particulate filter.Type: GrantFiled: April 10, 2015Date of Patent: September 13, 2016Assignee: Ford Global Technologies, LLCInventors: Shikui Kevin Chen, Kirk Andrew Parrish, Joseph Goode, Jeffrey Malcolm Travis, Norman Hiam Opolsky

Patent number: 8607549Abstract: In one approach a method for operating an engine including a DPF is provided. The method includes adjusting a post fuel injection amount based on a rate of change of engine torque during DPF regeneration. As one example, the adjusting includes reducing the amount when the rate of change is positive, and increasing the amount when the rate of change is negative. Furthermore, the method may also include delivering exhaust gas to a turbocharger turbine, to an oxidation catalyst, and then a DPF, the adjusting of the post fuel injection further based on thermal inertia of the turbocharger.Type: GrantFiled: January 21, 2010Date of Patent: December 17, 2013Assignee: Ford Global Technologies, LLCInventors: Jian Kong, Kevin Chen, Kirk Andrew Parrish, Jeff Malcolm Travis, Christopher Oberski, Michiel J.

Patent number: 8539824Abstract: Methods for monitoring and detecting undesired exotherms which may occur in an exhaust aftertreatment system coupled to a lean burning combustion engine are described. In one particular approach, an undesired exotherm may be indicated based on an expected oxygen depletion along a length of an exhaust aftertreatment system in the direction of exhaust gas flow of exhaust gas. For example, during DPF regeneration, a certain amount of oxygen is expected to be utilized for removing soot. If less oxygen is actually found in the exhaust downstream of the exhaust system, then an undesired exotherm may be present, as unintended reductant may be present in the exhaust and reacting exothermically with oxygen. Various mitigation actions may then be initiated in response to the indication of an undesired exotherm.Type: GrantFiled: March 29, 2013Date of Patent: September 24, 2013Assignee: Ford Global Technologies, LLCInventors: Michiel J.

Publication number: 20120023910Abstract: Systems and methods for controlling regeneration of a diesel particulate filter in a vehicle engine exhaust include detecting a distance of an object from the exhaust and controlling a regeneration event if the distance is less than a threshold value. The system and method may include a particulate filter disposed in the exhaust of the vehicle and a proximity sensor disposed adjacent an exhaust opening and positioned to detect presence of an object near the opening. A controller in communication with the proximity sensor is adapted for controlling regeneration of the particulate filter in response to the proximity sensor detecting the object near the opening.Type: ApplicationFiled: September 16, 2011Publication date: February 2, 2012Applicant: FORD GLOBAL TECHNOLOGIES, LLCInventors: Kirk Andrew Parrish, Norman Hiam Opolsky, Jeffrey Malcolm Travis, Joseph Goode, Scott Christopher Williams, Kevin Chen, Ryan Harrier
