    摘要: A system and a method for monitoring operation of an exhaust gas treatment system using an exhaust gas sensor in accordance with an exemplary embodiment is provided. The exhaust gas treatment system has an exhaust pipe configured to receive exhaust gases. The exhaust gas treatment system has an SCR catalyst coupled to the exhaust pipe. The exhaust gas treatment system has a urea delivery system configured to delivery urea upstream of the SCR catalyst. The exhaust gas sensor has an ammonia sensing electrode communicating with exhaust gases downstream of the SCR catalyst. The method includes generating a first output signal utilizing the ammonia sensing electrode, the first output signal being indicative of a first ammonia level. The method further includes generating a second output signal to induce the urea delivery system to deliver a predetermined flow rate of urea upstream of the SCR catalyst. The second output signal is based on the first output signal. The method further includes calculating a first ammonia level range utilizing at least a first engine operating parameter. Finally, the method includes generating a third output signal when the first ammonia level is outside the first ammonia level range. The third output signal indicates at least one of the urea delivery system having degraded operational performance, the SCR catalyst having degraded operational performance, and the exhaust gas sensor having degraded operational performance.

    摘要: In a fuel cell system, a reformer supplies reformate to a fuel cell stack. A portion of the reformate flow is diverted for analysis by a hydrocarbon analysis system. Residual hydrocarbons in the reformate may damage the anodes of the fuel cell stack. Although incompletely-reformed reformate may include a variety of hydrocarbon compounds, the invention simply measures methane as an indicator of the overall performance level of the reformer. A currently preferred embodiment includes a catalytic combustion methane sensor. Combustion air and reformate are delivered in a fixed ratio to the sensor via positive displacement pumps. The system can provide alarm means or optionally a shut-off means to protect a fuel cell stack from elevated levels of hydrocarbons in the reformate stream.

    摘要: A gas sensor system includes an ammonia-sensing cell for generating a signal upon exposure to an unknown gas comprising ammonia, an A/F cell for generating a signal upon exposure to hydrocarbons in the gas, a heater in thermal communication with the cells and a housing in which the cells and the heater are mounted. The housing permits an unknown gas to flow therethrough for contact with the cells, and there is a sensor control circuit in communication with the cells. The sensor control circuit is configured to utilize the signals from the cells to generate an ammonia concentration signal indicating the concentration of ammonia in the unknown gas. Ammonia may be sensed in an unknown gas by heating such cells to selected working temperatures, exposing them to an unknown gas, obtaining signals from the cells, and using the cell signals to determine the ammonia content.
