Abstract
An emissions control substrate. The emissions control substrate includes a first end in receipt of exhaust from an engine, and a second end from which exhaust exits the substrate. The second end is opposite to the first end. A plurality of channels are defined by sidewalls. The channels are arranged between the first end and the second end to direct exhaust from the engine through the emissions control substrate. The sidewalls at least one of filter and treat exhaust particulates as the exhaust passes through the sidewalls. The plurality of channels include at least one first channel defined by sidewalls that curve inward along lengths thereof from the first end to the second end.
Claims20
An emissions control substrate comprising:
- a first end in receipt of exhaust from an engine, and a second end from which exhaust exits the substrate, the second end is opposite to the first end;
- and
- a plurality of channels defined by sidewalls, the channels arranged between the first end and the second end to direct exhaust from the engine through the emissions control substrate, the sidewalls at least one of filter and treat exhaust particulates as the exhaust passes through the sidewalls;
- wherein the plurality of channels include at least one first channel defined by one or more sidewalls that curve inward along lengths thereof from the first end to the second end.
An emissions control substrate comprising:
- a first end in receipt of exhaust from an engine, and a second end from which exhaust exits the substrate, the second end is opposite to the first end;
- and
- a plurality of channels defined by one or more sidewalls, the channels arranged between the first end and the second end to direct exhaust from the engine through the emissions control substrate, the one or more sidewalls at least one of filter and treat exhaust particulates as the exhaust passes through the sidewalls;
- wherein the one or more sidewalls have a first thickness proximate to the first end and a second thickness proximate to the second, the first thickness is thinner than the second thickness.
An emissions control substrate comprising:
- a first end in receipt of exhaust from an engine, and a second end from which exhaust exits the substrate, the second end is opposite to the first end;
- and
- a plurality of channels defined by one or more sidewalls, the channels arranged between the first end and the second end to direct exhaust from the engine through the emissions control substrate, the one or more sidewalls at least one of filter and treat exhaust particulates as the exhaust passes through the sidewalls;
- and
- a plurality of pores defined by the one or more sidewalls that provide fluid communication between a first channel and neighboring second channels of the plurality of channels so exhaust can flow from the first channel to the neighboring channels through the plurality of pores;
- wherein the one or more sidewalls include a greater density of the plurality of pores proximate to the first end as compared to the second end.
