Abstract
A unique solution to measure NOx emissions is achieved less expensively and with much greater sensitivity than commercially available NOx sensors. A sensor's active materials are modified and operational algorithms are used to concurrently measure single ppm levels of NOx and NH3 with response times of one second or less. A combined NOx/NH3 sensor to have much finer control of an SCR system, thereby reducing NOx emissions and ammonia slip in a closed-loop device, all at lower cost than the current state-of-the-art solutions.
