x released into the atmosphere. DEF from a separate tank is injected into the exhaust pipeline, and the exhaust heat decomposes it to ammonia. Within the SCR catalyst, the NO Mark Quasius (1 May 2013). "2010 EPA Emissions Standards And Diesel Exhaust Fluid". FamilyRVing . Retrieved 3 December 2021. AdBlue® is made of a colourless mixture of high-purity urea (32.5%) and deionised water (67.5%), as set out in the ISO 22242 standard. Urea contains ammonia; the active ingredient in AdBlue® that reacts with NOx and neutralises it before it enters the atmosphere.

In the international standard defining DEF ( ISO 22241), it is referred to as AUS 32 (aqueous urea solution 32%). [5] DEF is also sold as AdBlue, a registered trademark of the German Association of the Automotive Industry. AdBlue is actually a synthetic urea which works by turning nitrogen oxide into harmless steam and nitrogen. It is stored in a tank, like fuel, and an increasing number of diesel vehicles, but typically those with larger engines, are being fitted with AdBlue tanks. However, certain manufacturers may refer to it simply as ‘Emissions Additive’. AdBlue is the generic marketing name for the product more technically known as diesel exhaust fluid (DEF). The term AdBlue is actually trademarked by the German Association of the Automotive Industry. Selective Catalytic Reduction is a clever technology system, which can send DEF into the exhaust stream of your diesel engine, to trigger a chemical reaction which can turn nitrogen oxides into nitrogen, water, and carbon dioxide (CO2). x levels even further. [8] In 2008, the concerns about compliance shifted to the infrastructure for DEF distribution. [9]Not especially. AdBlue is injected into the exhaust gases after the combustion process takes place and, thus, it has little or no effect on fuel consumption. There’s currently very little data to suggest that AdBlue affects fuel consumption either positively or negatively and any slight increases or decreases are factored in to the fuel consumption figure by manufacturers. My AdBlue warning light is on — what should I do? AdBlue is not injected into the engine as a fuel additive. It is added to the catalyst system in the car’s exhaust system. AdBlue is not fitted to every diesel car. As it is a registered trademark, not every manufacturer is authorised to use it.

If you do start your engine, then the damage could mean that you have to get the entire Selective Catalytic Reduction and AdBlue injection system replaced. If your car needs a dashboard reset after a top-up, make sure you complete this as per the instructions in your vehicle handbook. Air pollution caused mostly by traffic emissions contributes to some seven million deaths worldwide every year according to the World Health Organisation, with the Royal College of Physicians concluding that traffic fumes have played a big part in the early deaths of 40,000 people in the UK. Diesel engines specifically have been the subject of much criticism due to their higher levels of nitrogen oxide (NOx) emissions, which can negatively impact respiratory health. Although AdBlue is made up mostly of de-ionised water, you cannot use water to fill the tank. All trademarked AdBlue products meet a specific standard, so it is essential that you avoid using any other product that is not recommended as it could damage your car’s SCR system resulting in costly repairs that won’t be covered by a warranty.

How much AdBlue will my car use?

AdBlue® is classified as a non-hazardous product. It is biodegradable, water soluble and colourless. AdBlue® is a premium product that ensures a smooth-running SCR system in any make of vehicle, thus helping to reduce tailpipe emissions. You might want to wear gloves when dispensing AdBlue to keep your hands clean but AdBlue can easily be washed off with water. It might stain any clothing though. What do I do if I have spilt AdBlue fluid? AdBlue is essentially a mix of urea and deionised water. When your diesel car goes in for a service, your AdBlue should be topped up if necessary to make sure the exhaust gas cleaning system is working correctly and keeping emissions down.

Some high-mileage drivers carry 1-litre emergency bottles of AdBlue in the boot of their car, safe in the knowledge that should they need to fill the system at short notice, they will be able to do so. The fluid is corrosive, so some car companies do not recommend this. AdBlue and your car’s warranty

ISO 22241-4:2019 Diesel engines — NOx reduction agent AUS 32". ISO (International Organization for Standardization). 1 July 2019.Once you’ve completely run out of AdBlue you won’t be able to start your car. You’ll get plenty of warnings from your dashboard when your AdBlue is getting low though, so make sure to get on top of it as soon as possible. NH 2) 2CO + 4 NO + O 2 → 4 N 2 + 4 H 2O + 2CO 2 and 4 (NH 2) 2CO + 6 NO 2 → 7 N 2 + 8 H 2O + 4CO 2 and (NH 2) 2CO + NO + NO 2 → 2 N 2 + 2 H 2O + CO 2

Based on conservative estimates, AdBlue may require topping up every 5,000 to 8,000 miles although this will fluctuate based on manufacturer, model, and driving style.Clean Air Zones, such as London’s Ultra Low Emission Zone, require diesel cars and vans to be Euro6, otherwise a daily charge is required to enter the zone.

One of the latest techniques used to clean up diesel emissions is known as selective catalytic reduction (SCR). A liquid is used to treat exhaust gases and remove harmful pollutants, including nitrogen oxides(NOx), of which nitrogen dioxide (NO2) is the most harmful. AdBlue is a colourless, non-toxic mixture of urea and de-ionised water. It’s not actually blue at all.
