CX DEF – Diesel Exhaust Fluid
To meet new emission norms, vehicle manufacturers have largely turned to a process known as Selective Catalytic Reduction involving the injection of Diesel Exhaust Fluid (DEF) into existing gas circulatory systems which assists in the breakdown of harmful NOx.
The use of CX DEF is simple. Just pour directly into the tank (usually next to the fuel filler, in the boot, or under the bonnet) with a funnel. Follow any instructions given in your OEM handbook or on the pack to know your tank size. 5 litres should be enough to make sure your car will restart if you’ve run out completely.
Chemtex CX DEF is based on SCR (Selective Catalyst Reduction), a post treatment technology that treats exhaust gases downstream of the engine. Composed of 32.5% pure urea, a small quantity of CX DEF is injected into the exhaust upstream of a catalyst, where it vaporizes and decomposes to form ammonia and carbon dioxide. The ammonia is the desired product which in conjunction to the SCR catalyst, converts the NOx emissions into harmless nitrogen (N) and water (H2O).
Note: DEF is not injected into the engine as a fuel additive. It is added to the catalyst system in the car’s exhaust system.
