Abstract

A system is provided that includes an exhaust system. The exhaust system includes a first and a second conduit configured to receive an exhaust from an engine having at least two cylinders and configured to operate at a range of less than 600 revolutions per minute. The exhaust system further includes a first chamber configured to receive the exhaust from the first and the second conduits, and a second chamber downstream of the first chamber and fluidly coupled to the first chamber by using a third conduit. The exhaust system additionally includes a third chamber downstream of the second chamber and fluidly coupled to the second chamber by using a fourth and a fifth conduit and an exhaust stack downstream of the third chamber and fluidly coupled to the third chamber.

First claim

What is claimed is:

1. A system, comprising:
an exhaust system, comprising:
a first and a second conduit configured to receive an exhaust from an engine having at least two cylinders;
a first chamber configured to receive the exhaust from the first and the second conduits;
a second chamber downstream of the first chamber and fluidly coupled to the first chamber by using a third conduit;
a third chamber downstream of the second chamber and fluidly coupled to the second chamber by using a fourth and a fifth conduit;
an exhaust stack downstream of the third chamber and fluidly coupled to the third chamber;
an exhaust flow path through the first and second conduits, the first chamber, the third conduit, the second chamber, the fourth and fifth conduits, the third chamber, and the exhaust stack;
at least one valve coupled to the exhaust flow path; and
a controller communicatively coupled to the at least one valve, wherein the controller is configured to adjust the at least one valve to dynamically tune the exhaust system.

2. The system of claim 1 , wherein the first conduit comprises an inlet to outlet diameter ratio of approximately between 1 to 2.5.

3. The system of claim 1 , wherein the first conduit, the second conduit, or both, are directly angled with respect to side walls of the first chamber at an angle of between 30 to 60 degrees.

4. The system of claim 1 , wherein the third conduit is disposed approximately concentrically with respect to the first and the second chambers.

5. The system of claim 4 , wherein the third conduit protrudes into the first chamber and into the second chamber at a protrusion ratio of between 1 to 1 and 1 to 5.

6. The system of claim 1 , wherein the fourth and the fifth conduit are disposed side by side and abutting each other.

7. The system of claim 6 , wherein an outside diameter (OD) of each of the fourth and the fifth conduit is approximately half of an inside diameter (ID) of either of the second or the third chambers.

8. The system of claim 1 , wherein the at least one valve comprises a valve disposed inside the exhaust stack.

9. The system of claim 1 , wherein the at least one valve comprises a first valve disposed inside of the first conduit and a second valve disposed inside of the second conduit.

10. An exhaust system, comprising:
a compartment;
a first and second plate disposed inside the compartment and defining a first, a second, and a third partition of the compartment disposed sequentially one after another in a downstream direction along an axis of the compartment;
a first and a second conduit fluidly coupled to the first partition and configured to receive an exhaust from an engine having at least two cylinders, wherein the first and second conduits are acutely angled in the downstream direction relative to side walls of the compartment, wherein the second partition is disposed downstream of the first partition and is fluidly coupled to the first partition with a third conduit, and the third partition is disposed downstream of the second partition and is fluidly coupled to the second partition with a fourth conduit.

11. The system of claim 10 , comprising a first exhaust pipe having a first inlet fluidly coupled to the engine and a first outlet fluidly coupled to the first conduit; and a second exhaust pipe having a second inlet fluidly coupled to the engine and a second outlet fluidly coupled to the second conduit, wherein both the first and the second exhaust pipes are disposed at an angle of approximately between 15 to 60 degrees with respect to the first compartment.

12. The system of claim 10 , wherein the first plate is disposed at approximately between half a length of the compartment ±20%.

13. The system of claim 10 , wherein the second plate is disposed at approximately between ¾ of a length of the compartment ±20%.

14. The system of claim 10 , wherein the third conduit comprises a perforated pipe.

15. The system of claim 10 , wherein the third conduit protrudes into the first partition and into the second partition at a protrusion ratio of between 1 to 1 and 1 to 5.

16. The system of claim 10 , comprising:
an exhaust flow path through the first and second conduits, the first partition, the third conduit, the second partition, the fourth conduit, and the third partition;
at least one valve coupled to the exhaust flow path; and
a controller communicatively coupled to the at least one valve, wherein the controller is configured to adjust the at least one valve to dynamically tune the exhaust system.

17. A system, comprising:
an exhaust system, comprising:
a first conduit configured to receive an exhaust from an engine;
a first chamber configured to receive the exhaust from the first conduit;
a second chamber downstream of the first chamber and fluidly coupled to the first chamber with a second conduit;
a third chamber downstream of the second chamber and fluidly coupled to the second chamber with a third conduit; and
an exhaust outlet downstream of the third chamber and fluidly coupled to the third chamber;

an exhaust flow path through the first conduit, the first chamber, the second conduit, the second chamber, the third conduit, the third chamber, and the exhaust outlet;
at least one valve coupled to the exhaust flow path; and
a controller communicatively coupled to the at least one valve, wherein the controller is configured to adjust the at least one valve to dynamically tune the exhaust system.

18. The system of claim 17 , comprising the engine, wherein the engine is configured to operate at a range of between 100 and 1000 revolutions per minute.

19. The system of claim 17 , wherein the first conduit comprises an inlet to outlet diameter ratio of approximately between 1 to 2.5.

20. The system of claim 17 , wherein the at least one valve comprises at least one upstream valve disposed upstream of the second chamber and at least one downstream valve disposed downstream of the second chamber.

21. The system of claim 1 , wherein the exhaust system comprises at least one sensor configured to measure an operational parameter, and the controller is configured to adjust the at least one valve based on feedback from the at least one sensor to dynamically tune the exhaust system.

22. The system of claim 16 , comprising at least one sensor configured to measure an operational parameter, and the controller is configured to adjust the at least one valve based on feedback from the at least one sensor to dynamically tune the exhaust system.

23. The system of claim 17 , wherein the exhaust system comprises at least one sensor configured to measure an operational parameter, and the controller is configured to adjust the at least one valve based on feedback from the at least one sensor to dynamically tune the exhaust system.
