ABSTRACT:
An arrangement of dual element alternate flow exhaust cleaner and burner device for diesel engines is disclosed which provides trapping of particulates in the engine exhaust gases by their passage through either of the two elements. Collected particulates of carbon and other combustibles in the other nonactive element are electively incinerated by excess air or oxygen containing gas heated by a suitable burner or heater device. The incinerated products from the inactive element are redirected into the exhaust stream to pass through the active element for the cleansing of particulates remaining from the burnoff process before discharge.
