What is AdBlue ?
- Biodegradable, soluble in water and colourless, AdBlue® crystallises at -11°C and decomposes into ammonia from 80°C.
- AdBlue® is classified as a non-hazardous product.
- AdBlue® is used by Diesel vehicles equipped with SCR technology.
- AdBlue® must be stored indoor, protected from any directlight, and properlysealed.
SCR: SELECTIVE CATALYTIC REDUCTION
It is the name of the exhaust gases treatment technology which converts (inside a catalyst) the nitrogen oxides (NO) into water steam and nitrogen with the use of AdBlue®.
What is the use of AdBlue® ?AdBlue®
AdBlue® is used to reduce NO emissions
- AdBlue® is used byDiesel vehicles equipped with SCR technology.
- AdBlue® enables vehicles to satisfy the new standards of car manufacturers who have improved their exhaust systems to comply with the EURO 6 norm.
- AdBlue® is stored in an auxiliary tank separated from the Diesel tank.
First Heavy - Duty Trucks, Then Passenger Cars!
- AdBlue® is also used by heavy-duty trucks.
- Every new heavy-duty truck produced from October 2006 is equipped with the SCR technology, and also uses AdBlue®.
How does it work?Work
WHAT HAPPENS INSIDE THE ENGINE
Inside Diesel engines, NO (nitrogen oxides) are produced by the reaction of oxygen and nitrogen at the high temperatures caused by combustion.
WHAT HAPPENS INSIDE THE SCR
When NO react with the ammonia inside the catalyst, the harmful NO molecules are transformed into harmless nitrogen (N) and into water (HO).
WHAT HAPPENS INSIDE THE EXHAUST SYSTEM
AdBlue® is injected into the exhaust pipe, located before the SCR catalyst and after the engine. When heated inside the exhaust pipe, AdBlue® decomposes into ammonia (NH) and into carbondioxide (CO).
