AdBlue: What does it mean?

A liquid additive for diesel engines that helps convert harmful exhaust emissions into less harmful ones. It is stored in a separate tank and needs occasional topping up.

AdBlue: The long answer

AdBlue is a car-related term that refers to a type of diesel exhaust fluid used in vehicles equipped with Selective Catalytic Reduction (SCR) systems. It is a solution made of urea and deionised water that helps reduce harmful emissions, particularly nitrogen oxide (NOx), produced by diesel engines.

In the UK, AdBlue is commonly used in modern diesel vehicles to meet the stringent emission standards set by the European Union. It is stored in a separate tank within the vehicle and is injected into the exhaust system, where it reacts with the harmful nitrogen oxide emissions and converts them into harmless nitrogen and water vapour.

UK drivers may be familiar with AdBlue as it is required in many diesel cars, vans, and trucks, especially those registered after September 2015. The usage of AdBlue is monitored by the vehicle's onboard computer, and drivers need to ensure the AdBlue tank is regularly topped up to maintain proper emission control. Failure to refill AdBlue when required can result in reduced engine performance or even a vehicle's inability to start.

To refill AdBlue, UK drivers can purchase it from various retailers, including petrol stations, automotive stores, and online platforms. It is important to use the correct AdBlue formulation suitable for the vehicle to ensure optimal performance and emission control.

Overall, AdBlue plays a crucial role in reducing harmful emissions from diesel vehicles, helping to mitigate environmental impact and maintain compliance with emission regulations in the UK.
