SCR: Selective Catalytic Reduction (SCR) refers to the use of a reducing agent (such as NH3, liquid ammonia, urea) to "selectively" react with NOx in the flue gas under the action of a catalyst to produce non-toxic and non-polluting N2 and H2O.

The main pollutants emitted by diesel engines are HC (odor), CO, PM (black smoke), and NOx. HC causes odor and irritates the eyes, mouth, nose, throat, and respiratory tract. It is also toxic and carcinogenic. CO affects the respiratory system, hinders oxygen absorption, causes headaches, and can be fatal at high concentrations.
