An independently developed retrofit selective catalytic reduction (SCR) system was implemented onto a Euro 5 light duty vehicle, in order to comply with the Euro 6 nitrogen oxides (NOx) limit...
develop control-oriented SCR models. Several SCR models for the purposes of controller designs have be proposed recently, e.g., [10–13]. The following sub-section introduces the basic approaches of developing SCR control-oriented models and the main assumptions made for such control-oriented models. 14.2.2 Main SCR Reactions The SCR NO
10 sty 2024 · SCR systems represent a convergence of chemistry and engineering, providing a pathway to cleaner air and a healthier environment. The following will help to outline and define what SCR means, the system’s role in emissions reductions, and how it works to mitigate pollutants.
