What is DEF?

DEF stands for Diesel Exhaust Fluid. It is a solution of 32.5% automotive grade urea and 67.5% de-ionized water. When it is injected into diesel exhaust, it helps convert polluting NOx into hydrogen and water vapor.
DEF is a key component of Selective Catalytic Reduction technology, developed to meet the strict EPA and CEPA diesel emissions standards in place since January 2010.

The purity of your DEF product is critical as impurities will cause the fluid not to work properly. This means:

  • Your vehicle may not be meeting the emissions standards — you may be liable to fines
  • Your engine may use more fluid than required
  • You may not achieve optimum fuel consumption
  • You may damage your engine components over prolonged use of a compromised product

ABOUT SELECTIVE CATALYTIC REDUCTION (SCR)

The Environmental Protection Agencies in Canada and the US have legislated strict guidelines for decreasing the amount of allowed oxides of nitrogen (NOx) emissions from diesel engines on the road. In order to meet these standards, OEM’s have, for the most part, turned to Selective Catalytic Reduction technology (SCR). SCR requires the use of urea based Diesel Exhaust Fluid (DEF) and a catalytic converter to reduce (NOx) emissions. Measured amounts of DEF are injected into the exhaust from the engine, where it vapourizes and reacts chemically to form ammonia and carbon dioxide. The ammonia (NH3) is the product that changes the NOx to harmless water (H2O) and nitrogen (N2) with the SCR catalyst.

ADDED BENEFITS OF SCR TECHNOLOGY

Not only does SCR achieve the reduced emissions standards, but you can also achieve improved fuel performance by up to 5%. Less heat and fewer contaminants are generated internally, meaning SCR takes better care of your engine components, which is better for your vehicle in the long-term. The environmental benefits of SCR are clear.
