A filter assembly useful in collecting the particulate matter from a diesel engine onto surfaces on which the combustion vapors are condensed, and thereafter exposing the exhaust stream to catalytic reaction, is defined by a split cavity in which a row of kinematic filter discs is received. The filter discs are stacked in the assembly in a progressively finer opening size, each filter disc making an intimate contact with the assembly housing for cooling. In this manner condensation onto the discs is promoted to provide a liquid bed on which the particulate matter is trapped. The exhaust flow then passes through a coiled, corrugated catalyst surface for further reaction. A set of spring loaded bypass conduits is provided to allow diesel operation at such times when the filter plates and the catalytic coiled surface are clogged. The filter plates and the coiled catalyst strip can then be periodically removed and cleaned, for continued operation.

[ We claim:] [1.]1. A filter assembly conformed for attachment to the exhaust pipe of a diesel powerplant, comprising:a housing defined by a first and second shell hinged to each other along a respective edge to cooperatively form a generally cylindrical cavity;a plurality of first arcuate retainer brackets formed in the interior of said first housing shell;a plurality of second arcuate retainer brackets formed in the interior of said second housing shell, each in an opposed axial spacing relative a corresponding one of said first arcuate retainer;a first set of kinematic filter plates received in the common interior of said first and second shells in retained engagement between corresponding ones of said first and second arcuate brackets;a second set of kinematic filter plates received in the common interior of said first and second shells in retained engagement between corresponding others of said first and second arcuate brackets, said second filter plates including perforations smaller than said first filter plates;a strip of corrugated material coated on the exterior with a catalyst bearing coating wound into a coil with the corrugations overlying each other to form passages therebetween, received between further ones of said first and second retainer brackets to align said passages generally along the longitudinal axis of said housing; andattachment means for releasably securing said first and second shells to each other.
