Diesel Exhaust Fluid FAQ
What is Def?
Diesel Exhaust Fluid is a liquid solution made up of urea and de-ionized water. This solution is sprayed into the exhaust system of diesel vehicles and breaks down NOx emissions into water & nitrogen. The system that is responsible for this fluid is called Selective Catalytic Reduction also known as SCR. As of 2010 any diesel vehicle is manufactured with a SCR.
What is Selective Catalytic Reduction?
Also known as SCR, selective catalytic reductions uses a catalyst system in order to reduce the amount of harmful NOx emissions that are produced by diesel engines. SCR systems achieve this by spraying DEF into the exhaust stream. The DEF is then converted into ammonia on a catalyst. The ammonia is what breaks down the harmful emissions into nitrogen and water.
