Abstract
The current publication considers the benefits of placing a SCR system upstream of the DOC. This will enable rapid light-off of the upstream system. The tradeoff between engine out NOx levels, exhaust temperature, and dosing levels between upstream and downstream SCR will be compared with respect to achieving below 0.05 g/hp-hr NOx over the composite FTP and RMC. NOx conversion efficiency will also be compared with respect to N2O formation and NH3 slip.
