Abstract

A packaging system for enclosing an aftertreatment module associated with an engine is described. The packaging system includes a housing structure configured to enclose the aftertreatment module therein, the housing structure being coupled to an exhaust conduit of the engine. The housing structure includes a base portion and a plurality of side portions extending from the base portion. The base portion and the plurality of side portions define a chamber for receiving the aftertreatment module therein. Further, the packaging system includes a equipment rack configured to receive one or more components of the accessory system. The equipment rack includes a top end and a bottom end, the top end being distal from the bottom end and configured to couple with the base portion of the housing structure. The bottom end of the equipment rack is supported on a floor.

First claim

What is claimed is:

1. A packaging system for enclosing an aftertreatment module and an accessory system associated with an engine, the packaging system comprising:
a housing structure configured to enclose the after treatment module therein, the housing structure coupled to an exhaust conduit of the engine, the housing structure comprising:
a base portion; and
a plurality of side portions extending from the base portion, wherein the base portion and the plurality of side portions are together configured to define a chamber to receive the aftertreatment module therein; and

an equipment rack configured to receive one or more components of the accessory system, the equipment rack comprising:
a bottom end supported on a floor; and
a top end distal from the bottom end, the top end configured to couple with the base portion of the housing structure, wherein the equipment rack comprises a plurality of connecting members, wherein the plurality of connecting members are coupled together to define a space therein to accommodate the one or more components of the accessory system, wherein the plurality of connecting members comprises:
a first set of horizontal connecting members;
a second set of horizontal connecting members spaced apart from the first set of horizontal connecting members; and
a plurality of cross members connected between the first and second sets of horizontal connecting members,
wherein the first and second sets of horizontal connecting members and the plurality of cross members are together configured to define the space.

2. The packaging system of claim 1 , wherein the housing structure comprising:
an inlet port configured to couple with the exhaust conduit of the engine to receive exhaust gas therethrough and communicate with the aftertreatment module; and
an outlet port configured to discharge the exhaust gas from the aftertreatment module.

3. The packaging system of claim 2 , wherein the housing structure comprising:
a first duct defined adjacent to a top end thereof; and
a second duct defined adjacent to the top end spaced apart from the first duct,
wherein the outlet port is defined in a top portion extending between the first duct and the second duct.

4. The packaging system of claim 1 , wherein the plurality of side portions comprises:
a pair of first side portions extending from a first end and a second end of the base portion; and
a pair of second side portions extending between the pair of first side portions,
wherein the pair of first and second side portions are together configured to define the chamber.

5. The packaging system of claim 1 , wherein the housing structure comprising an opening for accessing the aftertreatment module therethrough.

6. The packaging system of claim 1 , wherein the equipment rack comprises a plurality of leg members extending from the second set of horizontal connecting members, the plurality of leg members are configured to be in contact with the floor.

7. The packaging system of claim 1 , wherein the first set of horizontal connecting members is coupled with the base portion of the housing structure.

8. An engine for a marine vessel comprising:
an exhaust conduit disposed parallel to a longitudinal axis of the engine, the exhaust conduit configured to receive exhaust gas from the engine therethrough; and
a packaging system for enclosing an aftertreatment module and an accessory system associated with the engine, the packaging system comprising:
a housing structure configured to enclose the aftertreatment module therein, the housing structure coupled to the exhaust conduit of the engine, the housing structure comprising:
a base portion; and
a plurality of side portions extending from the base portion, wherein the base portion and the plurality of side portions are together configured to define a chamber to receive the aftertreatment module therein; and

an equipment rack configured to receive one or more components of the accessory system, the equipment rack comprising:
a bottom end supported on a floor; and
a top end distal from the bottom end, the top end configured to couple with the base portion of the housing structure, wherein the equipment rack comprises a plurality of connecting members, wherein the plurality of connecting members are coupled together to define a space therein to accommodate the one or more components of the accessory system, wherein the plurality of connecting members comprises:
a first set of horizontal connecting members;
a second set of horizontal connecting members spaced apart from the first set of horizontal connecting members; and
a plurality of cross members connected between the first set of horizontal connecting members and the second sets of horizontal connecting members,
wherein the first set of horizontal connecting members, the second sets of horizontal connecting members, and the plurality of cross members are together configured to define the space.

9. The engine of claim 8 , wherein the housing structure comprising:
an inlet port configured to couple with the exhaust conduit of the engine to receive exhaust gas therethrough and communicate with the aftertreatment module; and
an outlet port configured to discharge the exhaust gas from the aftertreatment module.

10. The engine of claim 9 , wherein the housing structure comprising:
a first duct defined adjacent to a top end of the housing structure thereof; and
a second duct defined adjacent to the top end and spaced apart from the first duct,
wherein the outlet port is defined in a top portion extending between the first duct and the second duct.

11. The engine of claim 8 , wherein the plurality of side portions comprises:
a pair of first side portions extending from a first end and a second end of the base portion; and
a pair of second side portions extending between the pair of first side portions,
wherein the pair of first side portions and the pair of second side portions are together configured to define the chamber.

12. The engine of claim 11 , wherein the housing structure comprising an opening for accessing the aftertreatment module therethrough.

13. The engine of claim 8 , wherein the equipment rack comprises a plurality of leg members extending from the second set of horizontal connecting members, the plurality of leg members are configured to be in contact with the floor.

14. The engine of claim 8 , wherein the first set of horizontal connecting members is coupled with the base portion of the housing structure.

15. A packaging system for enclosing an aftertreatment module and an accessory system associated with an engine, the packaging system comprising:
a housing structure configured to enclose the aftertreatment module therein, the housing structure coupled to an exhaust conduit of the engine, the housing structure comprising:
a base portion; and
a plurality of side portions extending from the base portion, wherein the base portion and the plurality of side portions are together configured to define a chamber to receive the aftertreatment module therein;
