Abstract: 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.

Abstract: A system for removing matter from a filtering device includes a flow receiving device having a plurality of blocking portions. Each of the plurality of blocking portions is configured to substantially block a flow directed by a corresponding at least one of a plurality of filter passages of the filtering device. The system further includes a positioning assembly configured to assist in positioning the flow receiving device within the filtering device and relative to a filter media of the filtering device.

Abstract: An on-vehicle service system for removing matter from a filtering device of a single filtering device exhaust system includes a controllable filter bypass line fluidly connecting a first orifice of the filtering device of the single filtering device exhaust system to a second orifice of the filtering device. The service system also includes a receptacle fluidly connected to the filtering device and configured to collect at least a portion of the matter removed by the on-vehicle service system when a fluid is provided through a portion of the filter bypass line into the filtering device.

Abstract: According to an exemplary embodiment of the present disclosure, a method of detecting matter within a filtering device includes measuring a metric indicative of a first quantity of matter within the filtering device and removing a portion of the matter from the filtering device. The method also includes measuring a metric indicative of a second quantity of matter remaining within the filtering device.

Abstract: According to an exemplary embodiment of the present disclosure, a method of loading a filtering device includes measuring a metric indicative of an initial loading of the filtering device and desirably positioning a quantity of matter proximate the filtering device. The method also includes applying a negative pressure to the filtering device such that at least a portion of the quantity of matter is drawn into the filtering device. The method further includes measuring a metric indicative of a final loading of the filtering device.

Abstract: According to an exemplary embodiment of the present disclosure, a system for removing matter from a filtering device of a work machine includes a gas pressurization assembly. An element of the gas pressurization assembly is removably attachable to a first orifice of the filtering device without removing the filtering device from a work machine to which the filtering device is connected. The system also includes a heat source fluidly connected to the gas pressurization assembly.

Abstract: A system for removing matter from a filtering device includes a gas pressurization assembly. An element of the gas pressurization assembly is removably connectable to the filtering device and has a surface defining a plurality of orifices. The plurality of orifices is positioned on the surface to direct a flow beyond at least one blocking apparatus of the filtering device. The system further includes a matter collection assembly removably connectable to the filtering device.

Abstract: According to an exemplary embodiment of the present disclosure, a system for removing matter from a filtering device includes a gas pressurization assembly. An element of the assembly is removably attachable to a first orifice of the filtering device. The system also includes a vacuum source fluidly connected to a second orifice of the filtering device.
