Abstract:
An exhaust aftertreatment system configured to reduce nitrous oxide (N2O) formation includes a first selective catalytic reduction (SCR) catalyst. The first SCR catalyst is configured for low N2O formation and low ammonia (NH3) storage capacity. A second SCR catalyst is positioned downstream of the first SCR catalyst. The second SCR catalyst is configured for high NH3 storage capacity.
