    摘要： A system for sampling emission products from an emissions source, for example combustion engines including gasoline, diesel and natural gas engines, for subsequent measurement and analysis of the emission products. The system includes a dilution apparatus, a residence time chamber, a plurality of sampling probes within the residence time chamber, and a plurality of sampling trains connected to the sampling probes to take simultaneous representative emission samples for subsequent analysis. The system has particular use in quantifying chemical and toxic trace species from emissions sources. The results of the analysis can be used to formulate decisions on changes in engine design strategy, and can be used to determine the effectiveness of aftertreatment systems on the emissions source.

    摘要： A filter (10, 10a) includes a housing (12, 12a) extending along an axis (14). and having an inlet (16, 16a) at one axial end (18, 18a) of the housing and having an outlet (20, 20a) at a distally opposite axial end (22, 22a) of the housing. One or more pleated filter elements (44, 44a, 44b, 44c, 44d) in the housing are pleated along a plurality of bend lines (46, 48) extending axially. The filter element has a plurality of wall segments (50) extending in serpentine manner between the bend lines. The wall segments extend axially between upstream ends (52) and downstream ends (54) and define axial flow channels (58, 62) therebetween. The upstream ends of the wall segments are alternately sealed (56) to each other to defme a first set of flow channels (58) having open upstream ends (60), and a second set of flow channels (62) interdigitated with the first set of flow channels and having closed upstream ends (64). The downstream ends of the wall segments are alternately sealed to each other (66) such that the first set of flow channels have closed downstream ends (68), and the second set of flow channels have open downstream ends (70). Fluid to be filtered flows substantially directly axially through the filter element (44) or elements (44a, 44b, 44c, 44d), through the open upstream ends of the first set of flow channels then through the wall segments then through the open downstream ends of the second set of flow channels. A gasket (82, 82a, 82b, 82c) seals the filter element to the housing.

    摘要： Described herein are various embodiments of a reductant decomposition system. According to one representative embodiment, the reductant decomposition system includes an exhaust gas chamber including an inlet and outlet. The system also includes a first exhaust gas distribution component positioned within the chamber and communicable in exhaust gas receiving communication with the outlet. The first exhaust gas distribution component causes swirling exhaust gas flow patterns within the exhaust gas chamber. Additionally, the system includes a second exhaust gas distribution component positioned within the chamber and communicable in exhaust gas providing communication with the inlet. The second exhaust gas distribution component includes features that cause a swirling exhaust gas flow pattern within a space defined by the second exhaust gas distribution component. Further, the system includes a reductant injector coupled to the exhaust gas chamber. The reductant injector is communicable in reductant injecting communication with exhaust gas within the chamber.
