Abstract: A system for removing matter from a filtering device is disclosed. The system may have a reactive propellant located downstream of the filtering device. The reactive propellant may be configured to generate an impact wave.

Abstract: A system for treating exhaust gas from an engine is disclosed. The system may include a housing with a first longitudinal axis, an inlet port, and an outlet port. The housing may define a first flow path. A fluid treatment element may be arranged in the flow path. The system may also include a conduit defining a second longitudinal axis and forming a second flow path. The conduit may have first and second tubular portions generally aligned with the second longitudinal axis. The first tubular portion may have a first cross-section, and the second tubular portion may have a second cross-section. An inner diameter of the second cross-section may be less than an inner diameter of the first cross-section. The centerpoint of the first inner diameter may be offset from the centerpoint of the second inner diameter in a direction generally parallel to the first longitudinal axis.

Abstract: A system for treating exhaust gas from an engine is disclosed. The system may include a housing having an inlet port and an outlet port and defining a flow path therebetween. A fluid treatment element may be arranged in the flow path and configured to treat exhaust gas. A conduit may be fluidly connected with at least one of the housing ports and may have first and second tubular portions. The first portion may have a first cross-section with an inner diameter, and the second portion may have a generally elongated second cross-section with an inner width and an inner length. The inner length of the second cross-section of the conduit may be smaller than the inner diameter of the first cross-section of the conduit, and the inner width of the second cross-section of the conduit may be greater than the inner diameter of the first cross-section of the conduit.

The conduit is fluidly connected with at least one of the inlet port and the outlet port and includes a first port having a first axis and a second port having a second axis substantially perpendicular to the first axis. The first port has a first cross-section with an inner diameter. The second port has a second cross-section with an inner width and an inner length. The inner length of the second cross-section is smaller than the inner diameter of the first cross-section, and the inner width of the second cross-section is greater than the inner diameter of the first cross-section.
