Abstract

A dosing module includes an inlet manifold, an outlet manifold, a first branch, and a second branch. The inlet manifold is configured to selectively receive reductant from a pump. The outlet manifold is configured to selectively provide the reductant to a nozzle. The first branch is coupled to the inlet manifold and the outlet manifold. The first branch is configured to selectively provide the reductant from the inlet manifold to the outlet manifold. The first branch includes a first flow restrictor configured to restrict the reductant as the reductant is provided to the outlet manifold. The second branch is coupled to the inlet manifold and the outlet manifold. The second branch is configured to selectively provide the reductant from the inlet manifold to the outlet manifold separately from the first branch. The second branch includes a second flow restrictor that is configured to restrict the reductant.
