What is AdBlue?
AdBlue®, also known as Diesel Exhaust Fluid (DEF), is used in Selective Catalytic Reduction (SCR) systems on diesel engines to reduce nitrogen oxides (NOx).
What is Selective Catalytic Reduction (SCR)?
SCR is an acronym for Selective Catalytic Reduction. SCR is a technology that uses a urea based diesel exhaust fluid (DEF) and a catalytic converter to significantly reduce oxides of nitrogen (NOx) emissions. SCR is being used by almost all OEM manufacturers.
How does an SCR System work?
The purpose of the SCR system is to reduce levels of NOx (oxides of nitrogen emitted from engines) that are harmful to our health and the environment. SCR is the after treatment technology that treats exhaust gas downstream of the engine. Small quantities of diesel exhaust fluid (DEF) are injected into the exhaust upstream of a catalyst, where it vaporizes and decomposes to form ammonia and carbon dioxide. The ammonia (NH3) is the desired product, which in conjunction to the SCR catalyst, converts the NOx to harmless nitrogen (N2) and water (H2O).
What is BlueDEF for?
When used in an SCR system BlueDEF will reduce the levels of NOx emissions of those engines.
What is the composition of BlueDEF?
BlueDEF is a high-purity, 32.5 strength urea solution and deionizer water.
