What is the Function of AdBlue in Diesel Engines?

Model: (Various brands) Various
Part: AdBlue warning light

Video tutorial

AdBlue, combined with EGR technology, transforms nitrogen oxides emitted by diesel engines into non-polluting components. In this video, see how it works in practice: AdBlue is injected into the exhaust line upstream of the catalyst.

Through heat, urea decomposes into ammonia, and through a chemical reaction in the catalyst, ammonia combined with nitrogen oxides in the exhaust gases converts into nitrogen N2, a harmless gas, and water vapour, which is the main component of the air we breathe.

Adding AdBlue is therefore a winning choice for better air quality.
