  • Model based calibration of inferential sensing
    Patent number: 8700546
    Abstract: An inferential sensor module is incorporated into an engine simulation model. One or more parameters for the inferential sensor module are calibrated using one or more of engine measurement data and the engine simulation model. The calibration is performed such that a difference between an inferred signal predicted by the inferential sensor module and a signal measured on an engine is minimized. The inferential sensor module and the one or more calibrated parameters are loaded into an engine control unit in order to predict inferred variables.
    Type: Grant
    Filed: December 20, 2011
    Date of Patent: April 15, 2014
    Assignee: Honeywell International Inc.

  • Measurement of NO and NOfor control of selective catalytic reduction
    Patent number: 7613561
    Abstract: A selective catalytic reduction system includes a catalyst, a device to measure an amount of nitrogen oxide (NO), a device to measure an amount of nitrogen dioxide (NO2), a device to add an ammonia source, and a control unit to calculate the amount of ammonia source to add as a function of a ratio of an amount of nitrogen oxide and an amount of nitrogen dioxide or an absolute amount of nitrogen oxide and an absolute amount of nitrogen dioxide.
