What is Adblue and How Does Adblue Work

Diesel engines are growing in popularity as people seek to reduce their fuel emissions. They produce far fewer harmful emissions than petrol engines, and a lot of this is down to something called AdBlue.

If you own a diesel-powered Land Rover, Audi, or Jaguar, then the chances are your engine comes with AdBlue. Naturally, you may not have been aware of know this, or if you were aware but don’t really understand the importance. So, allow us to explain for you what is Adblue and how does Adblue work.

What is AdBlue?

The good news is, this is the easier of the two questions to answer! AdBlue is simply a solution that’s injected into your car. It’s made up of urea and water, and that’s pretty much it.

How does AdBlue work?

Now, this is where we take you back to chemistry class as we try to explain how AdBlue works in diesel engines. Well, when we talk about fuel emissions, we’re talking about a range of different things. There’s carbon dioxide, but there’s also nitrogen oxide as well. This is a harmful gas, and the role of AdBlue is to reduce this particular emission from your car.

So, how does it do it?

Well, the solution gets fed into the exhaust system where it reacts with the nitrogen oxide gas. This chemical reaction essentially separates the nitrogen and oxygen in nitrogen oxide. On their own, these two things are harmless. Not only that, but AdBlue also helps to break down the nitrogen dioxide, which means that if any does get released, it’s nowhere near as bad as before.

The result is a diesel engine that produces a remarkably reduced amount of dangerous nitrogen oxide gas.

All of this takes place without your knowledge as you drive your vehicle. There’s no button you need to press to inject AdBlue, it does it all by itself as part of the exhaust system. In fact, there’s a special name given to this; Selective Catalytic Reduction, or SCR for short. If your vehicle mentions SCR anywhere, then it’s an indication you have AdBlue technology inside it.

What are the main benefits of AdBlue?

Primarily, the benefit is that you lower your fuel emissions. More specifically, you significantly reduce the amount of nitrogen oxide your car produces. This makes a diesel vehicle far eco-friendlier, which instantly makes you a more environmentally aware driver!

Do all diesel engines have AdBlue?

Most new diesel cars do come with AdBlue as manufacturers realise it’s a smart way of cutting their fuel emissions. At Harwoods, we sell Audi, Jaguar, and Land Rover vehicles, all of which come with this cutting-edge technology.

It’s important to note that AdBlue will run out and has to be replaced from time to time. When you buy a vehicle from us, we’ll explain when you should top it up and how to do so. It varies from manufacturer to manufacturer, and some cars even have alerts that tell you when you’re running low. Hopefully, this has explained AdBlue in more detail, which shows you why diesel engines are becoming so popular!
