Emissions Control Substrate

An emissions control substrate for treating exhaust from an engine, the emissions control substrate comprising:

• a first end and a second end opposite the first end;
• a plurality of sidewalls defining a plurality of hexagonal cells extending between the first end and the second end;
• wash coats at interiors of the plurality of hexagonal cells;
• and
• a plurality of channels defined by the wash coats at the interiors of the plurality of hexagonal cells;
• wherein:
• at an inner region of the emissions control substrate through which a longitudinal axis of the emissions control substrate extends, for every group of three adjacent hexagonal cells of the plurality of hexagonal cells:
• two are plugged at the first end and open at the second end, and one is open at the first end and plugged at the second end;
• and
• at an outer region of the emissions control substrate surrounding the inner region, for every group of three adjacent hexagonal cells of the plurality of hexagonal cells:
• one is plugged at the first end and open at the second end, and two are open at the first end and plugged at the second end.
