  • Bifilar diesel exhaust filter construction using sintered metal fibers
    Patent number: 6942708
    Abstract: A diesel particulate filter construction, for filtering particulate from a flow of exhaust, includes a first layer of electrically resistive metal filter material in line with the flow of exhaust with particulate therein and a second layer of electrically resistive filter material which is also in line with the flow of exhaust with particulate therein. The layers are pleated cylinders concentrically positioned relative to one another. Current from a power supply is routed through the first layer and the second layer, which are electrically connected in series to one another. The layers are positioned so that exhaust flows through both the layers. Sufficient heat is generated by the flow of current through the layers to generate heat to, in turn, burn off entrapped particulate.
