Abstract
Improved systems and methods for dosing agent injection adaptation for a selective catalytic reduction (SCR) system of an engine of a vehicle involve an adaptation procedure that is generally divided into distinct phases based upon the requirement to obtain an accurate dosing adaptation. The phases themselves provide the specific functions of catalyst ammonia storage depletion, catalyst ammonia storage and NOx conversion stabilization, and adaptation value factor determination and verification.
