    摘要: Disclosed is a counterflow type filter trap system for filtering particulate matters from engine exhaust gases. A controller for receiving and sending information signals, is included. A metal fiber filter for capturing particulate matters included in the engine exhaust gases is provided. A back pressure sensor for sensing pressure difference between the inlet and the outlet of the metal fiber filter, is formed. A compressed air supplying portion is formed for injecting a compressed air in the opposite direction to the flow of the exhaust gases to separate the captured particulate matters from the metal fiber filter. A particulate matters collecting box for collecting the separated particulate matters and a guiding valve for guiding the separated particulate matters are provided. The life of the filter is lengthened and the apparatus has a simple structure. The filtering efficiency of the exhausted fumes is very high.

    摘要: The invention concerns a device for reducing the amount of soot particles discharged from the exhaust gas system of an internal combustion engine. Owing to the addition of an additive to the fuel, the ignition temperature of the soot particles during afterburning is reduced to between approximately 300 and 350.degree. C., so dropping far below the normal operating temperature of the unit. Consequently the regeneration process of the filter in the unit starts comparatively early. An essential component of the present invention is the so-called deep-bed filter which is composted of a plurality of rolled-up tubes of special ceramic thread and a heat-resistant resilient steel wire. The special production method and special construction of the ceramic stack according to the invention guarantee a satisfactory useful life of the soot filter which withstands vibrations and mechanical stresses.

    摘要: The device according to the present invention provides a relevant and, in some cases, total reduction of nitrogen oxide, carbon monoxide and particles of the unburnt gases of the exhaust which, before getting out of the silencer, are led between to electrodes kept at a high electrostastic potential difference, by means of a Van De Graaf generator or similar, so as to deviate the present and/or induced ions onto apposite containers, which may be replaced and regenerated after a determined working time.

    摘要: A particulate trap for diesel engine use which is less likely to vibrate or deform under exhaust pressures achieves goods results in particulate trapping properties, pressure drop, durability and regenerating properties. This trap has a filter element having a plurality of flat or cylindrical filters of three-dimensionally reticulated porous member. Longitudinally extending exhaust incoming and outgoing spaces are defined alternately between the adjacent filters by alternately closing the inlet and outlet ends of the spaces between the adjacent filters. Gas permeable reinforcing members are inserted in the exhaust outgoing spaces to prevent the filter from being deformed due to the difference between the pressure upstream and downstream of each filter produced when exhausts pass through the filters. Similar gas permeable reinforcing members may also be inserted in the exhaust incoming spaces or at both ends of the filter element to more positively prevent vibration of the filters.

    摘要: An exhaust gas purification filter comprising a metal porous body obtained by packing and fixing metal fibers having a mean fiber diameter of 5 to 40 .mu.m or heat resistant ceramic fibers having a mean fiber diameter of 1 to 40 .mu.m in a dispersed state into pores of a foamed structure porous body made of a heat-resistant metal so that a packing density of the resulting metal porous body is from 5 to 20%. The filter may be in a laminated structure by laminating the foregoing foamed structure porous body filled with or without the metal or ceramic fibers and a fiber structure porous body obtained by fixing metal fibers having a mean diameter of 5 to 40 .mu.m or heat-resistant ceramic fibers having a mean diameter of 1 to 40 .mu.m in a dispersed state so that a packing density is from 5 to 25% are laminated. By using the inventive filter for collecting PM (dry soot, fine particles and SOF) contained in an exhaust gas of a Diesel engine, a pressure loss for the exhaust gas is minimized while high collection efficiency is kept.
