A urea SCR system was combined with a DPF system to reduce NO_x and PM in a four liters turbocharged with intercooler diesel engine. Significant reduction in NO_x was observed at low exhaust gas temperatures by increasing NH₃ adsorption quantity in the SCR catalyst. Control logic of the NH₃ adsorption quantity for transient operation was developed based on the NH₃ adsorption characteristics on the SCR catalyst. It has been shown that NO_x can be reduced by 75% at the average SCR inlet gas temperature of 158 deg.C by adopting the NH₃ adsorption quantity control in the JE05 Mode.
