Abstract
In one embodiment, an exhaust treatment device comprises: a housing, a substrate disposed within the housing, and a mat wrapped around the substrate in a helical configuration, wherein the mat has a length that is greater than or equal to about three times the mat width and is disposed between the substrate and the housing. In another embodiment, a method for producing an exhaust treatment device comprises winding a mat around a substrate in a helical configuration to form a substrate/mat sub-assembly and disposing said substrate/mat sub-assembly in a housing. The mat has a length that is greater than or equal to about three times the mat width and is disposed between the substrate and the housing.
Claims12
An exhaust treatment device, comprising:
- a housing,
- a substrate disposed within said housing;
- and,
- a first mat wrapped around said substrate in a helical configuration, wherein said mat has a length that is greater than or equal to about three times the mat width and is disposed between the substrate and the housing.
A method for producing an exhaust treatment device, comprising:
- winding a mat around a substrate in a helical configuration to form a substrate/mat sub-assembly, wherein said mat has a length that is greater than or equal to about three times the mat width and is disposed between the substrate and the housing;
- and,
- disposing said substrate/mat sub-assembly in a housing.
An exhaust treatment device, comprising:
- a housing,
- a substrate disposed within said housing;
- and,
- a layered mat disposed between the substrate and the housing, wherein the layered mat is wrapped around said substrate greater than or equal to two revolutions.
A method for producing an exhaust treatment device, comprising:
- wrapping a mat around a substrate greater than or equal to two revolutions to form a substrate/layered mat sub-assembly;
- and,
- disposing said substrate/layered mat sub-assembly into a housing.
