1. 1. Model Predictive Urea Dosing Control Strategy for Heavy-Duty Diesel Vehicles

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Mathias Schmekel; [2023]
   Keywords : Model predictive control; Selective catalytic reduction; Nitrogen oxides; Modell-prediktiv reglering; Selektiv katalytisk reduktion; Kväveoxider;

   Abstract : Stricter requirements on the reduction of Nitrogen Oxides (NOx) in the emissions of heavy-duty diesel vehicles drives development for more efficient aftertreatment systems. An ammonia covered catalyst is one of the most successful technologies in reducing NOx by converting it into the harmless byproducts water and nitrogen. READ MORE

3. 2. Ammonia Dosing Control Strategy for heavy duty automotive SCR

   University essay from KTH/Fordonsdynamik

   Author : Rakshith Ramachandra; [2014]
   Keywords : ;

   Abstract : Selective Catalytic Reduction (SCR) has proven to be the frontrunner for the removal of nitrogen oxides (NOX) from exhaust gas. EURO VI emission regulations present a challenge from the control point of view, so as to achieve high NOX conversion while keeping the ammonia slip under control. READ MORE

4. 3. Modeling and Simulation of Urea Dosing System

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Zaki Ahmed; [2013]
   Keywords : Modeling; Simulation; Urea; Dosing;

   Abstract : To protect our health and environment from pollution, among others regulatory agencies in the European Union (EU) and legislation from the U.S. Environmental Protection Agency (EPA) has required that pollutants produced by diesel engines - such as nitrogen oxides (NOx), hydrocarbons (HC) and particulate matter (PM) - be reduced.
