Abstract

An emission reduction device which may be removably affixed to an engine's exhaust system. The device comprises a cylindrical carcass with a beveled opening in a diagonal line in its proximal part. A bobbin is affixed in the distal portion of the carcass. A cylindrical-shaped fibrous blanket may be inserted in the carcass and the fibrous blanket may be wrapped in a wire mesh. A second fiber mesh formed into a cone may be removably inserted in the cylindrical-shaped fibrous blanket with the larger diameter of the cone positioned proximally.

Claims (32)

1. A device for reducing emissions comprising:

a carcass defining a distal end and a proximal end, wherein said proximal end is affixed to an exhaust outlet of a combustion engine system;

a capsule affixed to said distal end of said carcass, wherein said capsule has a screen positioned at said capsule's distal end;

a bobbin positioned within said capsule; and

a fibrous blanket that is positioned inside said carcass to remove particles from exhaust gas expelled through said exhaust outlet, wherein said fibrous blanket is removably positioned inside said carcass to enable said fibrous blanket to be removed from said carcass after said fibrous blanket accumulates said particles.

2. The device of claim 1 further including a diaphragm wherein said diaphragm is formed into a cone.

3. The device of claim 1 , wherein said carcass is made of aluminum, steel, aluminized steel, or stainless steel.

4. The device of claim 1 , wherein said bobbin is constructed by wrapping two fabrics of different metal around a central point.

5. The device of claim 1 , wherein said carcass is removably affixed to said exhaust outlet.

6. The device of claim 1 , wherein said fibrous blanket is made of one or more of an aramid, a meta-aramid, a polyamide, a polyphenylene sulfide, a p-phenylene-1,3,4-oxadiazole, polytetraflouroethylene, and basalt.

7. The device of claim 1 , wherein said exhaust gas enters said device subsequent to exiting a muffler, such that said exhaust outlet is downstream in said exhaust system from said muffler.

8. The device of claim 1 , wherein at least some of said exhaust gas is expelled through a portion of said proximal end of said carcass.

9. The device of claim 8 , wherein at least some of said exhaust gas is expelled through said bobbin.

10. The device of claim 1 further comprising a second fibrous blanket affixed to a conductive mesh.

11. The device of claim 10 , wherein said conductive mesh is positioned around the perimeter of said fibrous blanket.

12. The device of claim 1 further including a diaphragm wherein said diaphragm is formed into a cone and said diaphragm is positioned inside said carcass.

13. The device of claim 12 wherein said diaphragm is made of one or more of an aramid, a meta-aramid, a polyamide, a polyphenylene sulfide, a p-phenylene-1,3,4-oxadiazole, polytetraflouroethylene, and basalt.

14. The device of claim 12 wherein said diaphragm is removable affixed to said carcass.

15. A method for reducing emissions comprising:

affixing a proximal end of a carcass to an exhaust outlet of a combustion engine system, wherein a capsule is positioned at a distal end of said carcass with a bobbin positioned within said capsule and a screen positioned at said capsule's distal end, a fibrous blanket is positioned inside said carcass to remove particles from exhaust gas expelled through said exhaust outlet, and said fibrous blanket is removably positioned inside said carcass to enable said fibrous blanket to be removed from said carcass after said fibrous blanket accumulates said particles.

16. The method of claim 15 further including providing a diaphragm wherein said diaphragm is formed into a cone.

17. The method of claim 15 , wherein said carcass is made of aluminum, steel, aluminized steel, or stainless steel.

18. The method of claim 15 , wherein said bobbin is constructed by wrapping two fabrics of different metal around a central point.

19. The method of claim 15 , wherein said carcass is removably affixed to said exhaust outlet.

20. The method of claim 15 , wherein said fibrous blanket is made of one or more of an aramid, a meta-aramid, a polyamide, a polyphenylene sulfide, a p-phenylene-1,3,4-oxadiazole, polytetraflouroethylene, and basalt.

21. The method of claim 15 , wherein affixing said proximal end of said carcass to said exhaust outlet comprises enabling at least some of said exhaust gas to be expelled through a portion of said proximal end of said carcass.

22. The method of claim 21 , wherein affixing said proximal end of said carcass to said exhaust outlet comprises enabling at least some of said exhaust gas to be expelled through said bobbin.

23. The method of claim 15 further comprising providing a second fibrous blanket affixed to a conductive mesh.

24. The method of claim 23 , wherein said conductive mesh is positioned around the perimeter of said fibrous blanket.

25. The method of claim 15 further including positioning inside said carcass a diaphragm wherein said diaphragm is formed into a cone.

26. The method of claim 25 wherein said diaphragm is made of one or more of an aramid, a meta-aramid, a polyamide, a polyphenylene sulfide, a p-phenylene-1,3,4-oxadiazole, polytetraflouroethylene, and basalt.

27. The method of claim 25 wherein said diaphragm is removably affixed to said carcass.
