Adblue Explained
November 12, 2018

It’s no secret that diesel engines produce a range of harmful air pollutants that can cause breathing and respiratory problems in vulnerable people. Nitrogen Oxide and Nitrogen Dioxide are the two most problematic emissions associated with diesel vehicles as they contribute to smog and acid rain.

Yet despite the ban on new petrol and diesel cars due to come into force in 2040, the industry has for some time been taking steps to tackle the issues surrounding diesel emissions. One of the ways it does this is with AdBlue, which you increasingly see stacked up on petrol station forecourts.


What is AdBlue?

AdBlue is formulated to work with Selective Catalytic Reduction (SCR) technology. SCR is designed to remove the most polluting oxides from diesel exhaust emissions and it uses AdBlue to achieve that.

AdBlue is essentially liquid urea. It is made up of 67.5 per cent ionised water and 32.5 per cent urea. When it gets hot, when the engine heats up, it releases ammonia which acts as the catalyst for a chemical reaction that converts Nitrogen Oxide into water and nitrogen – two completely harmless substances.

These are then expelled as exhaust gases, mitigating the damage done to the environment by diesel vehicles.


What Vehicles Use AdBlue?

AdBlue has traditionally been used in agricultural vehicles, lorries, buses and coaches which have been using SCR technology since the mid-2000s. However, the Euro VI emissions regulations, which were introduced in 2014/15, have driven a huge increase in the use of SCR technology in passenger cars. This is because Euro VI regs demanded Nitrogen Oxide emissions be cut by 56 per cent compared to Euro V.

This is a massive target and the only way most diesel cars of 1.6 litre and above will achieve it is via the use of AdBlue. So now, most are built with an AdBlue tank.
