Abstract: The present application relates generally to selective catalytic reduction (SCR) exhaust aftertreatment apparatuses, systems and methods. SCR exhaust aftertreatment is an important technology for reducing emissions of oxides of Nitrogen (NOx) from internal combustion engines. Providing effective NOx reduction during a variety of operating conditions including, for example, steady state conditions, transient conditions, low temperature conditions, high temperature conditions, low load conditions, high load conditions and other conditions remains a significant challenge. There is a substantial need for the unique apparatuses, systems and methods disclosed herein.
