Exhaust system for a work vehicle
An exhaust system for a work vehicle includes a mixer that includes a nozzle configured to receive a first exhaust flow along a lateral axis through a plurality of openings in a peripheral wall of the nozzle. The nozzle also receives a diesel exhaust fluid along a longitudinal axis through a longitudinal inlet. Further, the nozzle is configured to mix the first exhaust flow and the diesel exhaust fluid to form an exhaust solution. In addition, the mixer includes a conduit configured to receive the exhaust solution along the longitudinal axis. Moreover, the conduit has an opening configured to receive a portion of the nozzle, and the conduit is configured to receive a second exhaust flow through a gap formed between the nozzle and the conduit at the opening, and the opening is positioned downstream of the plurality of openings.
1. An exhaust system for a work vehicle comprising:
a mixer comprising:
a conduit configured to receive an exhaust solution including an exhaust and a diesel exhaust fluid along a longitudinal axis, wherein the conduit has a first opening configured to receive a first exhaust flow, and wherein a nozzle is disposed within the first opening, and the nozzle forms an annular opening configured to receive the first exhaust flow; and
a flow disruptor positioned downstream from the first opening, wherein the flow disruptor is configured to disrupt the flow of the exhaust solution;
wherein the nozzle is configured to receive a second exhaust flow through a plurality of slats and the diesel exhaust fluid along the longitudinal axis, and the plurality of slats are upstream of the flow disruptor.
2. The exhaust system of claim 1 , wherein each of the plurality of slats extends at least 30 degrees along a peripheral wall of the nozzle.
3. The exhaust system of claim 1 , wherein the mixer comprises another nozzle having a second opening configured to spray the diesel exhaust fluid downstream of at least a portion of the plurality of slats.
4. The exhaust system of claim 1 , wherein the nozzle has a converging section having a non-circular cross-section.
5. The exhaust system of claim 4 , wherein the converging section of the nozzle has a star-shaped cross-section.
6. The exhaust system of claim 1 , wherein the flow disruptor comprises a plurality of baffles extending from a top portion of the flow disruptor.
7. The exhaust system of claim 6 , wherein the plurality of baffles extend from the top portion to form a corresponding plurality of rows.
8. An exhaust system for a work vehicle comprising:
a mixer comprising:
a first nozzle configured to spray a diesel exhaust fluid through a longitudinal inlet;
a second nozzle coupled to the first nozzle, wherein the second nozzle is configured to receive a first exhaust flow along a lateral axis through a plurality of slats in a peripheral wall of the second nozzle and to receive the diesel exhaust fluid along a longitudinal axis through the longitudinal inlet, and the second nozzle is configured to mix the first exhaust flow and the diesel exhaust fluid to form an exhaust solution;
a conduit configured to receive the exhaust solution along the longitudinal axis, wherein the conduit has an opening configured to receive a portion of the second nozzle, the conduit is configured to receive a second exhaust flow through a gap formed between the second nozzle and the conduit at the opening, and the opening is positioned downstream of the plurality of openings; and
a flow disruptor downstream from the opening, wherein the flow disruptor is configured to disrupt the flow of the exhaust solution.
9. The exhaust system of claim 8 , wherein the first nozzle and the second nozzle are coupled via a slip joint.
10. The exhaust system of claim 8 , wherein the second nozzle has a converging section having a non-circular cross-section.
11. The exhaust system of claim 10 , wherein the converging section of the second nozzle has a star-shaped cross-section.
