    摘要: A filter internal flaw test apparatus includes a frame with a filter support and at least one pair of transducer supports. A filter is positioned in the test apparatus, and an ultrasound through transmission test and at least one ultrasound pulse echo test are performed on the filter. Data reliability is increased by positioning the pair of transducers in alignment with one another and pushing them toward one another using a force generator with a predetermined uniform force, such as via a regulated pneumatic actuator. A signal generating/receiving device is in communication with the transducers and provides the ability for analyzing the test results to determine whether the filter has an internal flaw, such as a crack or void that would render it unsatisfactory for use as a particulate filter.

    摘要: A particulate filter and a method for reducing pollutants are provided. The particulate filter comprises at least one first piece, said first piece comprising non-linear channels, and at least one second piece adjacent to the at least one first piece. The particulate filter is configured such that either the at least one first piece or the at least one second piece comprise either sintered metal fibers or porous metallic foam. The method comprises the steps of providing a particulate filter, said filter comprising, at least one first piece, said first piece comprising non-linear channels and at least one second piece adjacent to the at least one first piece, catalyzing the particulate filter with a catalyst, passing exhaust stream through the filter, filtering at least some soot from the exhaust stream, and chemically converting at least some NOx from the exhaust stream with the catalyst.
