Abstract
An aftertreatment system () includes a decomposition chamber (), a reductant pump (), a first dosing module (), a second dosing module (), and a controller (). The first dosing module () is coupled to the decomposition chamber () and configured to receive reductant from the reductant pump (). The second dosing module () is coupled to the decomposition chamber () and configured to receive reductant from the reductant pump () independent of the first dosing module (). The controller () is communicatively coupled to the first dosing module () and the second dosing module (). The controller () is configured to independently control a first volumetric flow rate of reductant provided from the first dosing module () into the decomposition chamber () and a second volumetric flow rate of reductant provided from the second dosing module () into the decomposition chamber ().
