Description
AdBlue is a DEF (Diesel Exhaust Fluid) which assists in reducing the harmful nitrogen-oxide emissions that are produced by diesel engines.
The introduction of this clever chemical is to aid car manufacturers in combating the ever-stricter emission targets such as Euro 6.
This was phased in from 2015 to help limit the impact on the environment and human health.
A colourless, non-toxic liquid, AdBlue is fundamentally made up of a water and urea.
In this instance, the urea is a remarkably pure, and of a much higher grade than that commonly found in glue, fertilisers or cosmetics.
The water that is used is de-mineralised, which is cleaner than what comes out of a regular tap.
