AdBlue is a non-toxic, non-explosive, non-flammable liquid that’s colourless in appearance. It is an Aqueous Urea Solution used with the Selective Catalytic Reduction system (SCR) to reduce emissions of oxides of nitrogen from the exhaust of diesel vehicles.
The Euro VI emissions regulations mean numbers of SCR-equipped vehicles needing AdBlue are set to rocket.
Euro VI is the latest update to the European emissions standards, which require diesel powered vehicles to reduce their emissions down to a certain level.
Previous releases saw more heavy duty vehicles including trucks, buses, agricultural & plant machinery being affected, but Euro VI now covers passenger cars.
To comply with Euro VI, recent diesel-powered cars use SCR technology to inject microscopic quantities of this liquid into the flow of exhaust gases. When the urea and water solution combines with exhaust emissions, it produces nitrogen and oxygen – harmless gases that occur naturally in the environment – by breaking down mono-nitrogen oxides (gases that can be harmful and are found particularly in the fumes from diesel exhausts).
