Abstract
An exhaust system for an agricultural vehicle is provided that includes a mixer configured to receive a spray of diesel exhaust fluid along a longitudinal axis of the mixer and an exhaust flow along a direction cross-wise to the longitudinal axis of the mixer. Additionally, the mixer is configured to mix the diesel exhaust fluid with the exhaust gas. Furthermore, the mixer is configured to discharge the exhaust gas along the longitudinal axis of the mixer.
Claims19
An exhaust system for an agricultural vehicle comprising:
- a mixer comprising:
- an outer conduit having a plurality of openings configured to receive a flow of exhaust gas along a direction cross-wise to a longitudinal axis of the mixer;
- and
- an inner conduit configured to the receive a spray of diesel exhaust fluid through a distal end of the inner conduit along the longitudinal axis of the mixer;
- wherein the outer conduit is disposed about the inner conduit, and configured to direct the flow of exhaust gas from the openings toward the distal end of the inner conduit to mix the spray of diesel exhaust fluid with the exhaust gas;
- and the inner conduit is configured to discharge the exhaust gas along the longitudinal axis of the mixer.
An exhaust system for an agricultural vehicle comprising:
- a mixer comprising:
- a conduit having a wall and a cone disposed at a distal end of the wall,
- a plurality of openings disposed along the wall and the cone, wherein the plurality of openings is configured to receive a flow of exhaust gas
- wherein the conduit is configured to receive a spray of diesel exhaust fluid longitudinal axis of the mixer, to receive the flow of exhaust gas along a direction cross-wise to the longitudinal axis of the mixer, to mix the diesel exhaust fluid with the exhaust gas, and to discharge the exhaust gas along the longitudinal axis of the mixer.
An exhaust system for an agricultural vehicle comprising:
- a housing configured to receive a flow of exhaust gas;
- a mixer configured to receive a spray of diesel exhaust fluid along a longitudinal axis of the mixer, and to receive the flow of exhaust gas from the housing along a direction cross-wise to the longitudinal axis of the mixer, wherein the mixer comprises:
- a conduit having a flared portion at a distal end;
- a protrusion having an opening, wherein the protrusion is positioned adjacent to the flared portion and extends from an interior of the housing into the flared portion to establish an annular orifice between the protrusion and the flared portion;
- wherein the flared portion is configured to receive the spray of diesel exhaust fluid through the opening, and to receive the flow of exhaust gas through the annular orifice, and the conduit is configured to discharge the exhaust gas along the longitudinal axis of the mixer.
