Roof-mounted muffler for system for generating electric power

1. An exhaust system for an electric power generation system comprising a housing configured to contain at least a portion of the electric power generation system, the housing defining a roof, the exhaust system comprising:

a muffler configured to suppress noise associated with operation of an engine associated with the electric power generation system,

wherein the muffler is configured to be mounted in the roof of the housing and includes an exit at the roof of the housing,

wherein the muffler is configured to form an outside surface of the roof,

wherein the exhaust system includes a conduit configured to provide flow communication between the engine and the muffler such that exhaust exits via the roof, and

wherein removal of the engine from the housing is facilitated by removal of the muffler from the roof, such that the engine can be lifted out of the housing.

2. The exhaust system of claim 1 , wherein the muffler defines an upper periphery, and a flange extends at least partially around the upper periphery of the muffler, and wherein the flange is configured to be operably coupled to a portion of the housing, such that the muffler is mounted in the roof of the housing.

3. The exhaust system of claim 1 , wherein the muffler defines a generally rectangular shape.

4. The exhaust system of claim 1 , further including at least one riser operably coupled to the muffler and configured to provide flow communication between the engine and the muffler.

5. The exhaust system of claim 1 , further including at least one extension operably coupled to the muffler and configured to provide flow communication from the muffler to an opening in the roof of the housing.

6. The exhaust system of claim 1 , wherein the muffler defines two opposing sides, and at least one of the opposing side defines an aperture configured to receive a dowel pin for maintaining a longitudinal position of the muffler with respect to the housing and permitting at least one of expansion and contraction of the muffler.

7. A trailer for at least partially containing an electric power generation system, the electric power generation system comprising an engine and an exhaust system comprising a conduit providing flow communication with a muffler, the trailer comprising:

a housing comprising

two opposing side walls; and

a roof extending between the side walls,

wherein the roof defines an opening configured to receive the muffler, with the muffler forming an outside surface of the roof,

wherein the housing is configured to contain the engine,

wherein the housing is configured such that the exhaust system extends between the engine and the roof, such that exhaust from the engine exits from the roof via the muffler, and

wherein the opening in the roof is configured to permit removal of the engine from the housing when the muffler is not received in the opening.

8. The housing of claim 7 , wherein the opening is a generally rectangular-shaped opening.

9. A system for generating electric power, the system comprising:

an engine configured to output mechanical power, the engine including an exhaust system including a muffler configured to suppress noise associated with operation of the engine;

an electric machine configured to convert mechanical power into electric power, the electric machine being operably coupled to the engine; and

a housing containing the engine and the electric machine, the housing including at least one wall and a roof,

wherein the roof defines an opening,

wherein the muffler is mounted in the opening in the roof and forms an outside surface of the roof,

wherein the exhaust system includes a conduit that extends between the engine and the muffler to provide flow communication between the engine and muffler such that exhaust from the engine exits from the roof via the muffler, and

wherein the opening in the roof is configured to permit removal of the engine when the muffler is not received in the opening.

10. The system of claim 9 , wherein the muffler defines an upper periphery, and further includes a flange extending at least partially around the upper periphery of the muffler, and wherein the muffler is operably coupled to the housing via the flange.

11. The system of claim 9 , wherein the muffler defines a generally rectangular shape.

12. The system of claim 9 , further including a cooling system configured to cool at least one of the engine and the electric machine.

13. The system of claim 9 , wherein the opening in the roof is configured to permit removal of the electric machine when the muffler is not received in the opening.

14. A method of removing an engine from a housing of an electric power generation system, wherein the electric power generation system comprises an engine contained in the housing and an exhaust system, and the housing includes a roof, wherein the exhaust system includes a conduit that extends between the engine and the roof of the housing, the method comprising:

removing a muffler mounted in an opening defined in the roof of the housing, the muffler forming an outside surface of the roof; and

lifting the engine out of the housing via the opening in the roof.
