    摘要： A particulate trap for use with a diesel engine is high in particulate trapping capacity and regenerating capacity and low in pressure drop, and yet is compact and inexpensive. This trap has a filter element made up of a plurality of tapered filter members formed from a fabric of heat-resistant metal fibers. The filter members have different diameters from each other and are nested concentrically one inside the other so that the adjacent filter members are positioned inversely. Each filter member is connected at its large-diameter end to the small-diameter end of the immediately outer filter member to alternately close the exhaust inlet and outlet ends of the gaps between the adjacent filter members. The filter element thus formed is mounted in a metal case provided in an exhaust line and used as a particulate trap. With this arrangement, it is possible to increase the particulate trapping area of the filter and the exhaust inlet openings without increasing the size of the entire trap. Such a trap is less likely to suffer pressure drop and is highly durable.

    摘要： An exhaust-gas purifying apparatus according to the present invention comprises an exhaust-gas filter for trapping particulates in exhaust gas from an engine, and a heating device located on the upper-course side of the filter, with respect to the flowing direction of the exhaust gas, the heating device including one or more conductive-ceramic heater elements, capable of heating and burning the particulates caught by the filter, and a heater case for holding the heater elements in position, so that the caught particulates are heated and burned by the heater elements when the flow resistance of the exhaust gas, flowing through the filter, is increased by the caught particulates, whereby the flow resistance is reduced. The heater element includes a fixed electrode portion, immovably fixed to the heater case, and a slidable electrode portion held slidably. An electrode member, fixed to the heater case, is brazed to the fixed electrode portion, and the heater element is bonded to the electrode member, so as to be clamped from both sides by solidified molten solder. The slidable electrode portion is supported by the heater case, for sliding motion in the direction of thermal deformation, so that the working life of the heater element is prolonged.
