ABSTRACT:
A smoke filter adapted to receive a stream of hot engine exhaust gas and to remove particulate carbon particles therefrom. The hot exhaust gas stream is passed progressively across catalytic beds which are spaced slightly apart within a closed casing. Each catalytic bed is mounted to an individual support member which is in turn cross braced with tension elements to protect the catalyst material from damage due to shock loading and high localized temperatures experienced within the catalyst bed.
