Apparatus, system, and method for filtration of a dosing fluid in an exhaust aftertreatment system
View Patent ↗An apparatus, system, and method are disclosed for a filter for filtering a dosing fluid in an exhaust aftertreatment system. The filter may comprise a dosing tank configured to contain a dosing fluid, a filter media disposed within the dosing tank, and a support structure supporting the filter media to form a pathway for a flow of dosing fluid. Beneficially, the apparatus, system, and method of the present invention reduce the cost of operation and manufacture of the SCR system.
1. A method for filtering a dosing fluid in an exhaust aftertreatment system, the method comprising:
containing a dosing fluid in a dosing tank, the tank containing a filter media and a pump that are both within the dosing tank;
urging the dosing fluid through the filter media; and
causing the dosing fluid to exit the tank using the pump from within the dosing tank.
2. The method of claim 1 , further comprising heating the dosing fluid within the dosing tank.
3. The method of claim 1 , further comprising pumping the dosing fluid through a recirculation line.
