A combination acoustical muffler and exhaust converter for use with internal combustion engines, comprising an elongated hollow cylinder adapted to be connected to a source of exhaust gas, screen means positioned at a plurality of longitudinally spaced locations within said cylinder for partitioning the cylinder into a plurality of chambers arranged in series flow relation with each other and with respect to the flow of exhaust gas through said cylinder, the screens having a silencing action on said exhaust gas, magnet means in one of said chambers for exerting a magnetic pressure on the gas passing therethrough to serve to separate ferrous particles from the exhaust gas stream, a packing material of mineral material, such as mineral wool, in another of said chambers for condensing moisture in said exhaust gas and for removing hydrocarbon therefrom, and a material such as a ceramic material of an extremely fine porous nature, in still another of said chambers for removing carbon monoxide from said exhaust gas.

A combination acoustical muffler and exhaust converter for use with internal combustion engines, comprising: A. an elongated hollow cylinder having an inlet end to receive exhaust gas, and having an outlet end; B. sets of filtering means positioned at a plurality of longitudinally spaced locations within the cylinder for filtering exhaust gas flowing therethrough and for partitioning the cylinder into a number of chambers arranged in series flow relation with one another, said filtering means being arranged and constructed to have a silencing action on the gas flowing through the cylinder without interfering with substantially straight axial gas flow therethrough, and each such set of filtering means comprising (1) a number of screen discs of different size mesh extending across the interior of the cylinder, (2) and the screen discs of each set of filtering means being arranged in a stack in contiguous relation to one another; C. packing material means in one of said chambers for condensing moisture in the exhaust gas and for removing hydrocarbon therefrom, said packing material means being comprised of fibers all disposed longitudinally of the cylinder; D. and means confined between two adjacent sets of screen discs which define a second one of said chambers, for removing carbon monoxide from the exhaust gas, said last named means extending completely across the interior of the cylinder.
