Horizontal muffler for an agricultural vehicle
View Patent ↗A horizontal muffler for an agricultural vehicle is provided. One agricultural vehicle includes an exhaust system having a muffler configured to direct exhaust out of an engine and to reduce a noise of the exhaust. The agricultural vehicle also includes a steering wheel configured to control steering of the agricultural vehicle. The muffler is disposed forward of the steering wheel relative to a direction of travel of the agricultural vehicle. Moreover, the muffler extends in a substantially horizontal direction such that a flow of the exhaust through the muffler is substantially parallel to a ground surface.
1. An agricultural vehicle comprising:
a body housing an engine;
an exhaust system having a muffler configured to direct exhaust out of the engine and to reduce a noise of the exhaust; and
a steering wheel configured to control steering of the agricultural vehicle;
wherein the muffler is disposed forward of the steering wheel relative to a direction of travel of the agricultural vehicle and is positioned outside of and adjacent to the body of the agricultural vehicle, and wherein the muffler extends in a substantially horizontal direction such that a flow of the exhaust through the muffler is substantially parallel to a ground surface; and
wherein the agricultural vehicle also comprises a plurality of front wheels and a plurality of rear wheels each configured to facilitate movement of the agricultural vehicle, and a fender extending around at least a portion of one of the front wheels, at least a portion of the muffler mounted directly over the fender.
2. The agricultural vehicle of claim 1 , wherein the muffler comprises a selective catalytic reduction (SCR) unit configured to reduce emissions of the exhaust.
3. The agricultural vehicle of claim 1 , wherein the muffler comprises an exhaust inlet and an exhaust outlet, and wherein the exhaust outlet is disposed farther from the steering wheel than the exhaust inlet along the horizontal direction.
4. The agricultural vehicle of claim 1 , comprising a cabin containing the steering wheel, wherein the muffler is positioned to be at least partially visible from within the cabin.
5. The agricultural vehicle of claim 1 , wherein the muffler extends toward a horizontal plane at an angle greater than zero and less than 20 degrees.
6. The agricultural vehicle of claim 1 , comprising a cabin containing the steering wheel, wherein the muffler is positioned to not be visible from within the cabin.
7. The agricultural vehicle of claim 1 , wherein the exhaust system comprises a heat shield configured to cover at least a portion of the muffler, the heat shield including a rear cover to block contact with a rear end of the muffler.
8. An agricultural vehicle comprising:
a body housing an engine;
an exhaust system having a muffler configured to direct exhaust out of the engine and to reduce a noise of the exhaust; and
a steering wheel configured to control steering of the agricultural vehicle;
wherein the muffler is disposed forward of the steering wheel relative to a direction of travel of the agricultural vehicle and is positioned outside of and adjacent to the body of the agricultural vehicle, and wherein the muffler extends in a substantially horizontal direction such that a flow of the exhaust through the muffler is substantially parallel to a ground surface, and
wherein the muffler extends longitudinally in a direction substantially parallel to the direction of travel of the agricultural vehicle such that the flow of the exhaust through the muffler is generally toward a front end of the agricultural vehicle.
9. The agricultural vehicle of claim 8 , wherein the muffler comprises a selective catalytic reduction (SCR) unit configured to reduce emissions of the exhaust.
10. The agricultural vehicle of claim 8 , wherein the muffler comprises an exhaust inlet and an exhaust outlet, and wherein the exhaust outlet is disposed farther from the steering wheel than the exhaust inlet along the horizontal direction.
11. The agricultural vehicle of claim 8 , comprising a cabin containing the steering wheel, wherein the muffler is positioned to be at least partially visible from within the cabin.
12. The agricultural vehicle of claim 8 , wherein the muffler extends toward a horizontal plane at an angle greater than zero and less than 20 degrees.
13. The agricultural vehicle of claim 8 , comprising a cabin containing the steering wheel, wherein the muffler is positioned to not be visible from within the cabin.
14. The agricultural vehicle of claim 8 , wherein the exhaust system comprises a heat shield configured to cover at least a portion of the muffler, the heat shield including a rear cover to block contact with a rear end of the muffler.
15. An agricultural vehicle comprising:
an exhaust system having a muffler configured to direct exhaust out of an engine and to reduce a noise of the exhaust; and
a steering wheel configured to control steering of the agricultural vehicle;
wherein the muffler is disposed forward of the steering wheel relative to a direction of travel of the agricultural vehicle, and wherein the muffler extends longitudinally in a direction substantially parallel to the direction of travel of the agricultural vehicle, such that a flow of the exhaust through the muffler is substantially parallel to a ground surface; and
wherein the agricultural vehicle also comprises a fender extending around at least a portion of a front wheel of the agricultural vehicle, at least a portion of the muffler mounted directly over the fender.
16. The agricultural vehicle of claim 15 , wherein the muffler comprises a selective catalytic reduction (SCR) unit configured to reduce emissions of the exhaust.
17. The agricultural vehicle of claim 15 , comprising a plurality of front wheels and a plurality of rear wheels each configured to facilitate movement of the agricultural vehicle.
18. The agricultural vehicle of claim 17 , wherein the muffler is disposed over one of the plurality of front wheels.
19. The agricultural vehicle of claim 15 , wherein the exhaust system comprises a heat shield configured to cover at least a portion of the muffler.
20. The agricultural vehicle of claim 19 , wherein the heat shield includes a rear cover to block contact with a rear end of the muffler.
21. The agricultural vehicle of claim 15 , further comprising a body housing the engine, wherein the muffler is positioned adjacent to the body of agricultural vehicle.
22. The agricultural vehicle of claim 15 , wherein the muffler extends toward a horizontal plane at an angle greater than zero and less than 20 degrees.
23. The agricultural vehicle of claim 15 , wherein the flow of the exhaust through the muffler is generally toward a front end of the agricultural vehicle.
