What is AdBlue and does your diesel car need it
If you own a diesel car, you might have heard of AdBlue, but you might not know exactly what it is and whether your vehicle needs it. In this article, we will explore AdBlue, what it is, how it works, and whether your diesel car needs it.
What is AdBlue?
AdBlue is a clear, non-toxic, and non-flammable solution that is used in diesel engines to reduce harmful emissions. It is a registered trademark of the German Association of the Automotive Industry (VDA) and is manufactured to a specific standard called ISO 22241.
How does AdBlue work?
AdBlue works by converting harmful nitrogen oxides (NOx) into harmless water vapor and nitrogen gas. It does this by injecting a precise amount of AdBlue into the exhaust system, where it reacts with the NOx in a process called Selective Catalytic Reduction (SCR). The SCR catalyst then breaks down the NOx into water and nitrogen, which are released harmlessly into the atmosphere.
Does your diesel car need AdBlue?
If you own a modern diesel car or light commercial vehicle (LCV) that meets the Euro 6 emissions standard, it is very likely that it will require AdBlue. Euro 6 is a set of emissions standards that were introduced in 2015 to reduce NOx emissions from diesel engines. The Euro 6 standard sets a limit of 0.08 grams of NOx per kilometre driven for diesel cars, which is a significant reduction from the previous Euro 5 standard.
AdBlue is required for diesel engines that use SCR technology to meet the Euro 6 emissions standard. Most diesel engines in Europe use SCR technology, so if you own a diesel car or LCV that was registered after September 2015, it is very likely that it will require AdBlue.
How do you know if your diesel car needs AdBlue?
If your diesel car requires AdBlue, it will have a separate AdBlue tank located next to the fuel tank. The AdBlue tank is usually smaller than the fuel tank and has a blue cap to distinguish it from the fuel cap. The dashboard will also have an AdBlue level indicator, which will warn you when the AdBlue level is low and needs to be topped up.
Where can you buy AdBlue?
AdBlue can be purchased from most petrol stations and automotive stores. It is usually sold in 5-liter or 10-liter bottles, or in larger containers for commercial vehicles. You can also purchase AdBlue online or from a dealership.
In conclusion, AdBlue is a solution that is used in modern diesel engines to reduce harmful emissions. If you own a diesel car or LCV that was registered after September 2015, it is very likely that it will require AdBlue to meet the Euro 6 emissions standard. If your car does require AdBlue, it will have a separate AdBlue tank located next to the fuel tank, and the dashboard will have an AdBlue level indicator. AdBlue can be purchased from most petrol stations and automotive stores, or online.
