What Does DEF Fluid Stand For?

Diesel Emission Fluid, or more commonly called DEF fluid, is a type of fluid that goes by two names:

  • Diesel exhaust fluid
  • Diesel emission fluid

In short, this is a fluid that is a non-hazardous solution of 32.5% urea and 67.5% de-ionized water. DEF is sprayed into the exhaust stream of the diesel vehicle and breaks down any dangerous NOx emissions into harmless water and nitrogen. It is important to understand that DEF is not a fuel additive and does not come into contact with diesel. It is stored in a separate tank. It is important to note that DEF fluid freezes at 12°F. If it is to be used, it needs to be melted or thawed to function properly. PTC heaters are one way to thaw out the fluid.

DEF Fluid Applications 

Diesel exhaust fluid makes using a diesel-run vehicle safer and cleaner for the environment. This is most notably due to Selective Catalytic Reduction (SRC) technology, which uses a catalyst system to break down dangerous NOx emissions by diesel engines into nitrogen and water. DEF and SRC work hand-in-hand to provide you with the reliable results you are looking for with your vehicle.
