摘要
An exhaust aftertreatment system includes a selective catalytic reduction (SCR) catalyst is disposed in an exhaust gas system of an internal combustion engine. A reductant injector is coupled to the exhaust gas stream at a position upstream of the SCR catalyst. A controller is configured to determine an NH3 slip condition and control operation of the exhaust aftertreatment system in response to the NH3 slip condition to improve deNOx efficiency and reduce NH3 slip.
