Investigation Of Urea Decomposition And Deposit Formation In Diesel Exhaust After-Treatment System, Anand Alembath
Doctoral Dissertations
“Urea-selective catalytic reduction (SCR) system has proved to be an effective solution to reduce NOx emissions in commercial vehicle (CV) diesel engines. A significant challenge in urea injection is to comprehend its decomposition chemistry that leads to formation of undesired deposits in the exhaust system unit. Due to complex interaction of multi-phase fluid flow and transport processes, significant uncertainty is associated with the identification of interacting factors that control the deposit initiation and its growth. To meet the future ultra-low NOx emissions and to deliver ammonia without deposit formation, there is an imminent need to develop the urea-SCR …

An Experimental Investigation Into The Effect Of Particulate Matter On Nox Reduction In A Scr Catalyst On A Dpf, Saksham Gupta
Dissertations, Master's Theses and Master's Reports
The study of NOx reduction across the SCRF® is presented in this report to understand the inlet and outlet NO, NO2, NH3 species from the SCRF®. The SCRF® is a prototype SCR catalyst on a Diesel Particulate Filter (DPF) that reduces NOx and PM at the downstream location. The SCRF® reduces the packaging volume of the aftertreatment components in order to reduce the cost, volume and weight of the aftertreatment system. A total of 12 experiments were performed on a Cummins ISB 2013 280 hp engine and the aftertreatment system. The …
