  • Reductant material deposit reduction in exhaust aftertreatment systems
    Patent number: 9341097
    Abstract: In one non-limiting embodiment, an apparatus for treating exhaust includes a reductant injector, an aftertreatment component including a NOx reduction catalyst, and a pathway for directing exhaust to the aftertreatment component. The pathway includes a constriction zone within which is positioned a mixing member. The constriction zone begins downstream of the reductant injector and upstream from the aftertreatment component. However, other embodiments, forms and applications are also envisioned.
    Type: Grant

    Date of Patent: May 17, 2016
    Assignee: Cummins Inc.
    Inventors: Mark Bays, Ian A. Package, Upendra Deshmukh, Douglas Mitchell, Jason Drost, Mihai Chiruta, Joseph Brault
  • System, method, and apparatus for determining aftertreatment fluid quality
    Patent number: 8863504
    Abstract: A method includes determining a first NOx conversion efficiency (?) value and determining that a diesel exhaust fluid (DEF) level has increased a threshold amount. Further, the method includes determining a second NOx conversion ? value and comparing the first NOx conversion ? value and the second NOx conversion ? value, determining a NOx conversion ? change in response to comparing, and determining a DEF quality indicator in response to the NOx conversion ? change.

  • System and method for providing cooling protection for an engine
    Patent number: 7509208
    Abstract: A method and system for controlling the temperature of an engine system is disclosed. The method and system comprise measuring a coolant temperature of the engine system; measuring noise factors of the engine system; and controlling components of the engine system to provide for an optimal operation of the engine based upon the measured temperature and measured noise factors. Accordingly, a system and method in accordance with the present invention combines measuring noise factors such as coolant pressure or coolant concentration and the temperature and then adjusting the threshold values for factors such as fan on temperature and engine protection derate. In so doing the coolant temperature can be controlled within an acceptable range of values.
