Publication number: 20230304430Abstract: Methods and systems are provided for a vehicle. In one example, a method may include acquiring measurements from at least one exhaust emission sensor of the vehicle, the exhaust emission sensor positioned to measure one of NOx, NH3, and O2 levels in exhaust gas of the vehicle. The measurements may be input into a machine learning model trained to output a predicted real-time amount of at least one exhaust gas constituent in the exhaust gas and operations of an emissions aftertreatment system may be assessed and adjusted based on the predicted real-time amount of the at least one exhaust gas constituent.Type: ApplicationFiled: March 25, 2022Publication date: September 28, 2023Inventors: Nathan Kempema, Conner Sharpe, David John Kubinski, Xiao Wu, Mehrdad Shahabi

Patent number: 10605137Abstract: Methods and systems are provided for detecting a missing exhaust catalyst based on water adsorption and related exothermic temperature rise by the catalyst. In one example, a method may include indicating an exhaust catalyst missing in response to an estimated exhaust temperature profile being different from an expected exhaust temperature profile. The estimated exhaust temperature profile may be based on exhaust temperature upstream and downstream of the catalyst.Type: GrantFiled: March 31, 2017Date of Patent: March 31, 2020Assignee: Ford Global Technologies, LLCInventors: Devesh Upadhyay, Michael Brendan Hopka, In Kwang Yoo, David John Kubinski

Patent number: 10364717Abstract: Methods are described for increasing the sensitivity of particulate matter detection in an exhaust system of a vehicle. An example particulate matter sensor assembly comprises a pair of planar interdigitated electrode structures held at a voltage bias with respect to each other. An alternate embodiment may comprise a planar interdigitated electrode pair, and a conducting plate assembly again held at a voltage bias with respect to the planar interdigitated electrode pair. The bias may overlay an additional electric field drive, which improves the capture of soot particles on the sensor assembly surface thereby increasing sensitivity of particulate matter sensors.Type: GrantFiled: September 8, 2017Date of Patent: July 30, 2019Assignee: Ford Global Technologies, LLCInventor: David John Kubinski

Patent number: 10309944Abstract: Particulate matter (PM) sensors and diagnostics performed using the PM sensors are disclosed. The PM sensors and diagnostics may be used in exhaust systems, such as vehicle exhaust systems, to detect soot. In at least one embodiment, an electrostatic particulate matter (PM) sensor is provided including first and second spaced apart electrodes forming a bulk gap therebetween having a bulk distance and a localized gap therebetween having a localized distance less than the bulk distance. A controller may be configured to control a voltage between the electrodes to induce an electrostatic discharge at the localized gap at a lower voltage than at the bulk gap. Various diagnostics may be performed using the disclosed PM sensors, including a wiring/continuity diagnostic, a soot detection plausibility diagnostic, and/or an installation diagnostic.Type: GrantFiled: September 6, 2016Date of Patent: June 4, 2019Assignee: Ford Global Technologies, LLCInventors: Michael Brendan Hopka, David John Kubinski, David Bilby, Michiel J.

Patent number: 10273906Abstract: Methods and systems are provided for controlling exhaust catalyst temperature during an engine cold-start by water injection. In one example, a method may include during the engine cold-start, injecting water into an intake of an engine based on the exhaust catalyst temperature and accumulating water molecules within an exhaust catalyst to generate heat within the exhaust catalyst. In this way, by generating and storing heat within the exhaust catalyst, the exhaust catalyst may be heated up rapidly, thus reducing catalyst light-off time.Type: GrantFiled: April 6, 2017Date of Patent: April 30, 2019Assignee: Ford Global Technologies, LLCInventors: Michael McQuillen, Daniel A. Makled, David John Kubinski, Richard E. Soltis

Patent number: 9745909Abstract: Methods are disclosed for determining an oxidation state of a catalyst using RF signals. The method may include introducing radio-frequency signals into a resonant chamber including a catalyst, modulating an air-fuel ratio of an engine upstream of the catalyst to generate a sequence of uniform pulses and at least one altered pulse that differs from the uniform pulses, and comparing a frequency response of two or more resonant modes of the radio-frequency signals during the sequence to determine an oxidation state of the catalyst. The method may further include adjusting the air-fuel ratio based on the comparing step. Two or more altered pulses may be inserted into the air-fuel ratio sequence. The altered pulse may have a pulse width and/or amplitude that differs from the uniform pulses. The methods may be used to adjust an air-fuel ratio to correct or impart a bias.Type: GrantFiled: October 1, 2015Date of Patent: August 29, 2017Assignee: Ford Global Technologies, LLCInventor: David John Kubinski
