ABSTRACT:
An automobile type exhaust gas lead filter is particularly applicable to diesel engine smoke reduction. It has a tubular housing with alumina coated metal wire fibers as the filter bed, which is centrally located. There are open spaces forming plenums at the ends of the housing. And, the inlet and outlet pipes have baffles in alignment therewith to prevent direct impingement of exhaust gases on the coated wire. Also, the baffles are spaced from the inside ends of the pipes to minimize pressure drops.
