RISAn NOx Sensor-Based Direct Algebraic Approach-Newton Observer for Urea Selective Catalytic Reduction System State Estimations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: NOx sensor-based state estimations for urea-based selective catalytic reduction (SCR) systems have attracted much attention in the past several years because of their significant importance in achieving high NOx conversion ...
Estimation of Ammonia Storage Nonuniformity for Urea-Based Selective Catalytic Reduction Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Ammonia storage nonuniformity has a significant impact on the emission reduction performance of urea-based selective catalytic reduction (SCR) systems. In this paper, a unique SCR platform with two catalysts in a parallel ...
Experimental Study and Model Predictive Control of a Lean-Burn Gasoline Engine Coupled With a Passive Selective Catalytic Reduction System
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: Lean-burn gasoline engines have demonstrated 10–20% engine efficiency gain over stoichiometric engines and are widely considered as a promising technology for meeting the 54.5 miles-per-gallon (mpg) corporate average fuel ...
