Abstract
An exhaust treatment device for treating an exhaust gas stream combines the functionalities of a catalytic particulate filter and a NOx absorber catalyst into a single integral device and is disposed in an exhaust conduit. By combining the functionalities of the catalytic particulate filter and a NOx absorber catalyst into a single integral device, the exhaust treatment device eliminates the temperature losses inherent to the heat capacity of one catalytic device placed in front of the other.
