Abstract
A reactant delivery system for engine exhaust gas treatment may include a tank in which a reactant is received, a pumping device, a pressure relief device, and a reactant distribution device. The pumping device may have an inlet disposed within the interior of the tank to receive the reactant, and an outlet through which the reactant is discharged. The pressure relief device may have an inlet in fluid communication with the outlet of the pumping device, a primary outlet to discharge the reactant under pressure to a downstream location, and a bypass outlet through which at least some of the reactant discharged from the pumping device is selectively discharged. And the reactant distribution device may be in fluid communication with the bypass outlet of the pressure relief device and have a plurality of outlets to distribute the reactant to at least two different locations within the tank.
