Abstract
Systems and methods are provided for reducing exhaust NOx species using a monolith substrate having a plurality of channels configured with radially varying cell density. An injector injects reductant into the substrate unobstructedly, without use of a mixer. In some embodiments, a twist angle of the channels is based on a distance from an inlet of the substrate and varies exponentially as a function of the distance.
