Pressurized tank vehicular fluid delivery system

摘要

Systems and methods for delivering a vehicular fluid to a component of the vehicle. A reductant delivery system of a selective catalytic reduction system delivers the vehicular fluid to the component of the vehicle. The reductant delivery system includes a compressed air source, a tank in fluid communication with the compressed air source, a dosing module in fluid communication with the tank, and a control module electrically coupled to the compressed air source. The tank may contain a diesel exhaust fluid and the dosing module is in fluid communication with the component that receives the diesel exhaust fluid. The control module regulates an amount of air pressure in the tank to deliver the vehicular fluid to the dosing module. The system omits a vehicular fluid pump such that the compressed air from the compressed air source pressurizes the dosing module with the vehicular fluid.

主权项

1. A system for supplying a fluid in a vehicle, comprising:
a compressed air source; a tank in fluid communication with the compressed air source, the tank configured to contain a vehicular fluid, the tank including an outlet at a bottom of a lower portion of the tank; a dosing module in fluid communication with the tank via the outlet, the dosing module in fluid communication with a component of a vehicle that receives the vehicular fluid; and a controller mechanism coupled to the compressed air source and the dosing module, the controller mechanism configured to:
regulate an amount of air pressure in the tank, andcontrol the dosing of the vehicular fluid using the dosing module, wherein the system does not include a vehicular fluid pump such that compressed air from the compressed air source pressurizes the dosing module with the vehicular fluid.
