Abstract

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.
