    摘要: A system for and process of is provided for calculating SCR conversion efficiency by applying a reference control signal by which a urea dosing module is controlled to an NOx conversion value respectively in absorption and release modes of NH3 according to a loading amount of the NH3 determined from the SCR efficiency map. The system and process may include a process of determining the NOx conversion value according to a loading amount of NH3, a process of detecting the reference control signal of the dosing module injecting the urea solution, and a process of calculating the SCR conversion efficiency based on the determined NOx conversion value and reference control signal of the dosing module.
