Abstract: A catalyst supported on a substrate includes a heater embedded in a sub-region of the substrate to heat a local region of the catalyst. The amount of ammonia stored on the catalyst may be determined and controlled through conductivity measurements in the locally heated portion of the system described.

Abstract: Various systems and methods are described for controlling an engine in a vehicle in response to an equilibrium value of an exhaust gas constituent generated from an exhaust gas sensor. One example method comprises during engine fueling below a threshold amount where at least one intake valve and one exhaust valve of the engine are operating: generating an equilibrium value of an exhaust gas constituent reading of the exhaust gas sensor, the equilibrium value based on a trajectory of the exhaust gas constituent reading, and under selected engine combusting conditions, adjusting the sensor signal based on the equilibrium value.

Abstract: A method is disclosed for operating an electrochemical gas sensor with a measuring electrode pair and a pumping electrode pair. The method includes obtaining a measurement of the interfering species at a location spatially adjacent to a measuring electrode of the measuring electrode pair; and adjusting one or more of an operation or an output processing of the electrochemical gas sensor based on the measurement of the interfering species. In this manner, the measurement of the interfering species may be used to adjust the removal rates of the interfering species and/or to adjust an offset of an analyte measurement to compensate for the presence of the interfering species.

Abstract: A system, comprising of a catalyst supported on a substrate positioned in an engine exhaust, a heater embedded in a sub-region of the substrate to heat a local region of the catalyst, and an electrode coupled in the local sub-region of the substrate of the catalyst. The catalyst reduces NOx emissions by reacting it with a reductant such as ammonia. The amount of ammonia stored on the catalyst may be determined and controlled through conductivity measurements in the locally heated portion of the system described.
