The Diesel Exhaust Fluid (AdBlue) That’s Helping The UK Cut Harmful Emissions

Diesel-powered vehicles and equipment account for almost half of all nitrogen oxides (NOx) and more than two thirds of all particulate matter (PM) emissions from US transportation sources.

Further research has revealed that diesel engines are carcinogenic and cause significant health problems and as such, diesels have recently become subject to a lot of negative publicity thanks to the amount of harmful emissions they product.

The government decided that NOx emissions needed to be reduced with the Euro 6 standard, leaving car manufacturers no choice but to overcome another obstacle introduced by legislators. To combat this, they introduced ‘wet’ diesel particulate filters (DPFs) that require AdBlue, which was a relatively cost-effective and simple way to cut the amount of harmful emissions released.

To pass Euro 6 regulations, AdBlue is used in an ever-increasing number of diesel-powered vehicles. In fact,  Heavy Goods Vehicles are required by law to use the additive since 2006 (all Euro IV and Euro V vehicles weighing over 7.5 tonnes) and many new models now also have an AdBlue tank (but this is not required by law yet).

So, unless you drive a Heavy Goods Vehicle above 7.5 tonnes or diesel engine car that’s fitted with Selective Catalytic Reduction (SCR), it’s likely you’ve never heard of it.

What is AdBlue?

AdBlue is officially called AUS32 which stands for Aqueous Urea Solution 32.5%. It contains 32.5% of high purity water and 67.5% of deionised water and is key in helping cut harmful emissions released from diesel exhausts. It goes in a separate tank from the fuel itself as it should never come into contact with it.

Why is AdBlue needed?

The diesel exhaust fluid (DEF) has recently become key in helping cut harmful emissions produced by diesel engines. With the government putting increasing pressure on diesel car manufacturers to do something about the substantial amount of harmful emissions released by exhausts, AdBlue was introduced by the automotive industry to help improve our health and cut down on Nitrogen Oxide.

How does AdBlue work?

Polluting chemicals and compounds, including Nitrogen Oxide and Nitrogen Dioxide are produced when diesel engines burn fuel. These elements build up in the air and produce smog and acid rain. AdBlue works through a process called Selective Catalytic Reduction (SCR) to remove these harmful emissions.

When AdBlue is sprayed into a diesel exhaust, it releases ammonia which is a catalyst to a chemical reaction. This converts dangerous chemicals into Nitrogen, water vapour and CO2 which are unharmful to our lungs and atmosphere. The diesel will never come into contact with AdBlue because it’s stored in a separate container.
