DEF (Diesel Exhaust fluid)

DEF (Diesel Exhaust Fluid) is one of the key elements of the SCR (Selective Catalytic Reduction) process. It is a nontoxic solution of 67.5% purified water and 32.5% urea. When injected into hot exhaust as a fine mist and passed over a catalyst, DEF helps convert NOx (nitrogen oxide) into nitrogen gas and water vapor—two clean and harmless components of the air we breathe.

DEF is stable, colorless and odorless, and meets accepted international standards for purity and composition.

Facts & Figures about DEF

  • DEF is a clear, non-toxic, non-flammable, and non-hazardous organic compound.
  • To achieve the nitrogen oxide (NOX) levels required by the EPA 2010 standard, most engine manufacturers are utilizing Selective Catalytic Reduction (SCR) systems that require the addition of DEF.
  • DEF can be stored at temperatures of between 12°F (-11°C) and 86°F (30°C) for a maximum of 12 months.
  • Consumption rates vary but are usually around 5% of diesel fuel consumed. It can be expected that 5 litres of DEF fluid will be used for every 100 litres of diesel fuel.
