Abstract
A reductant impingement device includes a proximal end having an impingement pin with a convex surface; and a distal end having a body concentric with a longitudinal axis of the impingement pin. The distal end includes a first surface and a second surface opposite the first surface. A plurality of inner channels connects the first surface and the second surface, and a plurality of outer channels connects the first surface and the second surface, where the plurality of inner channels are disposed in a circular array at a first radial distance from a longitudinal axis of the impingement pin, and the plurality of outer channels are disposed in a circular array at a second distance from the longitudinal axis of the impingement pin.
