What is AdBlue: The Key to Cleaner Engines?

AdBlue is a fluid which is automatically sprayed into a car’s exhaust system to reduce the nitrous oxide emissions of diesel engines. AdBlue is made of a mixture of urea and deionised water. The widespread usage of AdBlue in modern diesel cars coincided with stricter Euro 6 emissions standards that have been in effect since 2016. AdBlue makes it much easier to lower the emissions of diesel cars so they comply with these regulations

AdBlue is a light, colourless 32.5% Aqueous Urea Solution used as a fluid in the latest generation of diesel-powered Euro IV, Euro V & Euro VI trucks. (All Diesel Car Compatible)

Why is AdBlue Indispensable?

Car makers have to abide by a huge number of rules, a major amount of which aim to address environmental concerns. The most recent set of emissions regulations, known as Euro 6, represented a particularly big challenge for diesel engines. One of the main goals is to minimise nitrogen-oxide emissions.

The technology is known as selective catalytic reduction, or SCR. Despite only recently becoming widely used in diesel cars, it’s existed for decades. The process involves injecting precise amounts of a liquid into the exhaust system and neutralising the harmful emissions by way of a chemical reaction.

Emission Reduction

AdBlue is crucial for reducing harmful nitrogen oxide (NOx) emissions from diesel engines, which is essential for improving air quality and addressing environmental concerns.

Environmental Compliance

AdBlue ensures that diesel vehicles meet stringent emission regulations and standards imposed by authorities, enabling businesses and individuals to comply with legal requirements and avoid penalties.

Enhanced Efficiency

AdBlue not only reduces NOx emissions from diesel engines but also enhances fuel efficiency. It optimizes the combustion process, improving mileage and lowering fuel consumption. By using AdBlue, drivers can enjoy cost savings while contributing to a greener and more efficient transportation system.

How does AdBlue work?

Through a process called Selective Catalytic Reduction (SCR), AdBlue reduces the harmful emissions which are released by diesel engines as the fuel is burned. AUS 32 (Aqueous Urea Solution 32.5%) is the official name for AdBlue although the majority of people who use this additive call it AdBlue. It consists of 32.5% high purity urea and 67.5% deionized water, giving it its scientific name AUS32.

As diesel burns within your vehicle’s engine, it is forced through the exhaust system and expelled out into the air that we breathe. Before the emissions are released, the AdBlue formula is sprayed onto the harmful gases and the SCR Catalyst breaks down the bad stuff (Nitrous Oxides).

Once that’s done, all that’s left is nitrogen, water and CO2 to be expelled from the exhaust system. Check out the diagram below which shows AdBlue’s Nitrous Oxide reduction in action.

The AdBlue trademark is currently held by the German Association of the Automobile Industry (VDA (Verband der Automobilindustrie)). Clicking the link will take you to their page with additional notes about this diesel additive.

Modern heavy goods vehicles fitted with SCR technology are required to use AdBlue by law. As of October 2006, all vehicles above 7.5 tonnes are manufactured with this technology. This includes industrial vehicles, buses and trucks. Your diesel fuel will never come into contact with the solution as it is stored in its own designated tank with a sensor system and gauge. It is sprayed onto the exhaust fumes soon after combustion and works from there.

FAQ

To comply with Euro 6 regulations, many new diesel-powered cars built since 2016 utilise Selective Catalytic Reduction (SCR) technology to inject small amounts of AdBlue into the car’s exhaust gases. When this solution combines with the exhaust emissions, it breaks down the harmful mono-nitrogen oxides present in diesel exhaust. This technology has been employed in buses and heavy lorries for a considerable period, hence its efficacy has been demonstrated, and its dependability is currently better than ever.

Manufacturers have not yet provided any data indicating that AdBlue has a detrimental impact on fuel consumption. In the United Kingdom, the economy figures for a new diesel car on the market will consider any effects resulting from the use of AdBlue.

Advancements in engine technology, alterations in the methodology of calculating economy figures, and various other factors make it essentially impossible to identify differences in fuel consumption solely attributed to the use of AdBlue when comparing new and older cars.

AdBlue is a non-toxic liquid that has a transparent appearance and is essentially a solution of water and urea, a compound present in urine. However, the urea used in AdBlue is of an exceptionally pure and higher grade than the urea employed in cosmetics, adhesives, or fertilizers. Similarly, the water used in AdBlue is demineralised, making it significantly cleaner than tap water.

Your AdBlue levels should be checked and topped up at every service and your dealer will happily refill it at other times when required but this is rarely the cheapest option. AdBlue is also sold in bottles at fuel stations and you can also order it online.

On various popular diesel models, the AdBlue filler is positioned behind the vehicle’s fuel filler cap. It is typically smaller in size compared to the main fuel filler and is distinguished by a blue cap and clear markings indicating that it is exclusively intended for AdBlue usage.

If you are uncertain about how to refill your car’s AdBlue, it is advisable to consult the owner’s manual for instructions on accessing the AdBlue tank. It should not be a complex process. Additionally, it is a good idea to request the salesman to demonstrate how to refill the AdBlue during the handover of a new car.

Another alternative for refilling your AdBlue tank is to utilize an AdBlue pump. These pumps are commonly available at major filling stations, particularly in the HGV (Heavy Goods Vehicle) lanes. Some pumps are equipped with separate fueling nozzles for HGVs and cars.

AdBlue pumps are primarily intended for use by truckers and are often more cost-effective and less messy than attempting to refill your tank using a plastic bottle. Initially, filling stations with AdBlue pumps were primarily limited to main routes and motorways, but their availability has increased in recent years with the addition of more stations offering this facility.

All diesel cars that utilise AdBlue will provide you with plenty of warning if you’re running low. You’ll typically receive a dashboard notification at around 1,500 miles before running out, accompanied by an amber warning light. This warning will persist every time you restart your car until the AdBlue levels have been topped up to the desired level.

Disregarding the AdBlue warning light on your dashboard is strongly discouraged in all circumstances. If you continue driving without sufficient AdBlue, your car’s performance is likely to be affected as it enters “limp mode,” reducing your driving speed and potentially disabling certain features like the stereo or air conditioning to conserve power and reduce emissions output.

In most modern vehicles, once you come to a stop, the car cannot be restarted if the AdBlue tank is completely empty. However, this situation can be easily avoided as AdBlue refills are simple to perform and typically inexpensive if you compare prices and carry out the refill yourself.
