A urea SCR system was combined with a DPF system to reduce NO x and PM in a four litters turbocharged with intercooler diesel engine. Significant reductions in NO x were observed at low exhaust gas temperatures by increasing NH 3 adsorption quantity in the SCR catalyst. NH 3 adsorption control logic was developed for transient operation based on the NH 3 adsorption characteristics. 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 NH 3 adsorption control in the JE05 Mode.
