Abstract:
A diesel exhaust fluid (DEF) delivery system and method for operating same. The method includes controlling a pump to operate at an idle speed to pressurize a pressure line. The method includes controlling a backflow dosing module (BFDM) valve to open to allow an amount of the DEF to flow into a fluid storage tank through a backflow line. The method includes determining a dosing request, a first dosing actuation request for the first dosing valve and a second dosing actuation request for the second dosing valve based on the dosing request. The method includes, when a sum of the first and second dosing actuation requests is less than 100%, controlling the BFDM valve to close when either of the first and second dosing valves is open; and controlling the BFDM valve to open when the first dosing valve is closed and the second dosing valve is closed.

Claim (Index 4):
The system of  claim 1 , wherein the electronic controller is configured to, when the sum of the first and second dosing actuation requests is greater than or equal to 100%,\n receive the system pressure from the pressure sensor; control the backflow dosing module valve to close; determine a pressure disturbance based on the dosing request; determine a pump control request based on the system pressure and an operating pressure; determine a feed forward control value based on the pressure disturbance; generate an adjusted control request based on the pump control request and the feed forward control value; control the first and second dosing valves to open and close based on the first and second dosing valve actuation requests; and control the pump based on the adjusted control request.
