Abstract: The invention relates to a new method and system for optimizing the efficiency of an automotive catalytic converter by adjusting the engine air/fuel ratio based on estimates of the actual amount of oxidants stored in the catalyst. The oxidant storage capacity of the catalyst is adjusted by controlling engine spark in response to an estimate of a current amount of oxidants stored in the catalyst and an estimate of the total available oxidant storage capacity of the catalyst. To maintain engine speed in spite of adjustments to the engine spark, the engine air mass is also adjusted.

Abstract: A method for reducing phase noise and distortion in a digitally converted image in which only a selected subset of the video frames that represent the image are displayed. The selected subset is comprised of reference video frames, where a new reference frame is captured for display after determining that a pixel of an inbound video frame exceeds a certain threshold of change as compared to a corresponding pixel of a previously captured reference frame. The pixel comparison is performed by comparing corresponding numerical values representing each of the pixel's color values, red, green, and blue, or by comparing corresponding numerical values representing a composite color value. The threshold determination is performed by comparing the absolute value of the difference between each of the corresponding pixel values to a pre-selected change threshold value.

Abstract: A method for accurately diagnosing deterioration in an emission control system for a lean burn internal combustion engine is presented. The emission control system includes an Active Lean NOx (ALNC) Catalyst and a system for injecting a hydrocarbon-based reductant into the ALNC thereby improving its NOx conversion efficiency. The method teaches calculating a rate of change of exotherm across the ALNC and differentiating between deterioration of the ALNC and deterioration of the reductant injection system based on the magnitude and the sign of the rate of change of the exotherm. Once the diagnosis of deterioration is made, and the deteriorated component is identified, appropriate corrective measures, such as adjusting or discontinuing the reductant injection amount, and setting diagnostic codes, are taken.
