Abstract
The exhaust gas recirculation system which includes a diverter valve system for selectively directing recirculated gas through an aftercooler includes a self regenerating catalyzed particulate filter which is positioned upstream of the aftercooler of the system to prevent soot from accumulating on the heat exchange surfaces of the aftercooler. Removal of the soot from the exhaust gas increases efficiency and longevity of the aftercooler.
