  • Delay based feed forward strategy to control pressure in a diesel exhaust fluid delivery system
    Patent number: 10724414
    Abstract: A system for regulating pressure in a diesel exhaust fluid delivery system. The system includes a first dosing valve, a pump, a hydraulic line, and an electronic processor. The electronic processor is configured to determine a dosing demand, determine a time delay between the first dosing valve opening and the pump activating, and determine a first threshold time and a second threshold time based on the time delay. The electronic processor is also configured to activate a timer. When the timer reaches the first threshold time, the electronic processor is configured to freeze the dosing demand and activate the pump based on the dosing demand. When the timer reaches the second threshold time, the electronic processor is configured to open the first dosing valve and release the freeze on the dosing demand.
