RISObserver-Based Estimation of Aging Condition for Selective Catalytic Reduction Systems in Vehicle Applications
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents two observers for estimating the aging condition of selective catalytic reduction (SCR) systems in vehicle applications. SCR systems have been widely recognized as one of the leading engine exhaust gas ...
NOx Sensor Ammonia Cross Sensitivity Factor Estimation in Diesel Engine Selective Catalytic Reduction Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Since the NOx sensor is crosssensitive to gaseous ammonia, the reading of NOx sensor may not be accurate when the gaseous ammonia is involved and it is a combination of the actual NOx concentration plus the ammonia ...
