Diesel Exhaust Fluid
What Is DEF?
Diesel Exhaust Fluid - DEF - is a urea-based chemical reactant designed specifically for use in SCR systems to reduce NOx emissions.
How DEF Works
Selective Catalytic Reduction (SCR) is an exhaust after treatment system that injects a small amount of a chemical called Diesel Exhaust Fluid (DEF) into the exhaust. DEF is mixed with exhaust in the presence of a catalyst turning NOx (oxides of nitrogen – a harmful pollutant that contributes to smog and acid rain) into harmless nitrogen and water vapor.
