An emissions control substrate for treating exhaust from an engine including a plurality of hexagonal cells extending between a first end and a second end of the substrate. Wash coats are at an interior of the hexagonal cells. At an inner region of the 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. At an outer region of the 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.

Emissions control substrate

A vehicle includes an engine, a fueling system, an exhaust assembly, and a controller. The fueling system controls fuel to the engine. The exhaust assembly releases combustion gas from the engine and includes at least one sensor and a catalytic converter. The controller is configured to control the engine, the fueling system and the exhaust assembly. The controller evaluates engine state and an output from the at least one sensor and commands a fueling strategy to control an oxygen storage capacity of the catalytic converter based on the engine state and output from the at least one sensor.
