  • Methods and systems for prediction of sensor response time
    Patent number: 10488315
    Abstract: Methods and systems are provided for predicting response time of a particulate matter (PM) sensor and resetting the PM sensor upon completion of response time prediction, independent of actual or predicted soot load on PM sensor. Soot accumulation data collected during steady state vehicle operation may be fitted with a time-based polynomial function and sensor output and regeneration schedule may be estimated from the curve fit even if the overall signal is noisy.
    Type: Grant
    Filed: February 12, 2016
    Date of Patent: November 26, 2019

  • Method for evaluating degradation of a particulate matter sensor after an engine start
    Patent number: 8959979
    Abstract: A system for improving operation of an engine having a particulate matter sensor is presented. The system may be used to improve engine operation during cold starts especially under conditions where water vapor or entrained water droplets are present in vehicle exhaust gases. In one embodiment, particulate sensor degradation is indicated in response to an output of said particulate matter sensor staying below a threshold as engine temperature increases past the dewpoint temperature.

  • System and method for monitoring reductant quality
    Patent number: 8769935
    Abstract: A method of operating an internal combustion engine having a reductant delivery and storage system in an emission control system, comprising of correlating a change in a monitored operating condition with a refill event to determine whether a reductant-diluting substance has been added to the reductant storage system; and limiting vehicle operation based on the correlation.

  • System for an engine having a particulate matter sensor
    Patent number: 8707678
    Abstract: A system for improving operation of an engine having a particulate matter sensor is presented. The system may be used to improve engine operation during cold starts especially under conditions where water vapor or entrained water droplets are present in vehicle exhaust gases. In one embodiment, an engine controller that activates a heater of an exhaust gas sensor after an output of a particulate matter sensor exceeds a threshold value after an engine is started.
