  • Patent number: 8393146
    Abstract: An exhaust emission control device is provided which is compact in size and has favorable dispersibility of exhaust gas from a muffling structure 2 to an oxidation catalyst 3. The muffling structure 2 arranged upstream of the oxidation catalyst in a direction D of gas flow has a dispersion plate 6 for dividing the interior of the casing 5 into dispersion chambers 7a and 7b upstream and downstream in the direction D of gas flow, respectively, and an inner pipe 8 inserted from outside of and into the chamber 7a and with a tip end fixed to the dispersion plate 6 and circumferentially formed with pores 9a, 9b, 9c and 9d having diameters gradually reduced in the order in the direction D of gas flow from upstream to downstream. The dispersion plate 6 facing the dispersion chambers 7a and 7b is formed with a plurality of radially-outward-larger-diametered and radially-inward-smaller-diametered pores 14, 15 and 16.

  • Patent number: 8327630
    Abstract: An exhaust system including an exhaust emission control device with a post treatment unit (e.g., a selective reduction catalyst) for depuration of exhaust gas flowing therethrough is disclosed. The exhaust system includes a layout that introduces the exhaust gas into the post-treatment unit through a turnabout. An introductory part encircles an inlet end of the post-treatment unit and receives the exhaust gas through an exhaust inlet port from a direction substantially perpendicular to an axis of the selective reduction catalyst. The introduction part is formed with a first depression cambered away from the inlet end of the selective reduction catalyst and approaching toward the inlet end of the selective reduction catalyst as the first depression extends away from the exhaust inlet port and toward an introduction direction of the exhaust gas, thereby promoting uniformity of the exhaust gas flow entering the post-treatment unit.

  • Publication number: 20110214416
    Abstract: An object of the invention is to make it possible to introduce exhaust gas 3 into a post-treatment unit such as selective reduction catalyst 6 through turnabout, with distribution of flow of the exhaust gas 3 being uniformized. Disclosed is an exhaust emission control device with a selective reduction catalyst 6 (post-treatment unit) for depuration of the exhaust gas 3 through passing therethrough being arranged in an exhaust system, a layout being applied which introduces the exhaust gas 3 into the selective reduction catalyst 6 through turnabout. An introductory part 14 is provided which encircles an inlet end of the selective reduction catalyst 6 and guides the exhaust gas 3 through the exhaust inlet port 13 from a direction substantially perpendicular to an axis of the selective reduction catalyst 6.

  • Patent number: 7345766
    Abstract: A measuring chamber for photo-acoustical sensors for the continuous measurement of radiation-absorbing substances, in particular of radiation-absorbing particles, in gaseous samples includes at least one entry and at least one exit for the samples, a tube section with microphone that allows for the flow-through of the sample in longitudinal direction, and at least one entry and exit point for a laser beam that is aligned with the tube section, and whereby these entry and exit points are both arranged at a distance from the measuring tube by at least one chamber with a cross-sectional area that is expanded relative to the tube section.
