  • Patent number: 8142552
    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.
    Type: Grant
    Filed: June 29, 2007
    Date of Patent: March 27, 2012
    Assignee: Caterpillar Inc.

  • Patent number: 8097055
    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.

  • Patent number: 8092563
    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 housing has an inlet and an outlet port and defines a flow path therebetween. The fluid treatment element is arranged in the flow path. 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.
