AdBlue is a high quality urea solution that is easy to use

AdBlue is the registered trademark for AUS32, or Aqueous Urea Solution 32.5% that is used with the Selective Catalytic Reduction system (SCR) to reduce emissions of oxides of nitrogen from the exhaust of UK diesel vehicles. AdBlue is a 32.5% solution of high-purity urea in de-mineralized water that is clear, non-toxic and safe to handle. It is non explosive, non flammable nor harmful to the environment. AdBlue is classified under the minimum risk category of transportable fluids. It is not a fuel, nor a fuel additive and needs to be used in a dedicated tank in your heavy-duty vehicle. It is replenished in a similar way to refuelling diesel. Should you spill AdBlue on your hands, simply wash it off with water

How much AdBlue do I need?

Average consumption of AdBlue in UK vehicles is generally 5% of diesel use, so you will need to tank much less for AdBlue then you do for diesel. You will use about 5 liters of AdBlue to every 100 liters of diesel.
Why should I choose SCR with AdBlue over other technologies?
AdBlue combined with SCR offers you a fuel efficient solution, with lower CO2 emissions then competitive solutions. All major European and North American truck manufacturers currently offer SCR equipped models. The future Euro VI emission standard is set to reinforce the demand for this technology

Why does AdBlue quality matter?

Various actions can affect the quality of AdBlue. To prevent contamination, it is imperative that foreign matters do not come into contact with the solution. Using contaminated AdBlue can lead to expensive catalyst replacement costs. The AdBlue trademark is currently held by the German Association of the Automobile Industry (VDA), who ensure quality standards are maintained in accordance with ISO 22241 specifications. Ensure that you only buy a reagent for your heavy duty vehicles that bears the name AdBlue with the registered trademark (®) on the product label.  For this reason, Blue1 is using specific dedicated materials in their pump installations to ensure that your AdBlue meets the required quality standards.

What is SCR technology for trucks, buses and off road heavy duty vehicles?

SCR stands for an after treatment technology called Selective Catalytic Reduction. This technology requires the use of a reagent called AUS 32 (also known as AdBlue, DEF in North America or ARLA 32 in Brazil) to reduce the NOx. Almost all major heavy-duty vehicles manufacturers have decided to use this technology to meet the new emission legislation on NOx emissions. Competitive technologies offer a less beneficial fuel efficiency and higher CO2 emissions. So SCR is the most cost effective solution to meet NOx emission standards.
The main components of the SCR system are the SCR catalyst, the AdBlue injection unit, the AdBlue tank and the AdBlue dosing control unit. AdBlue is injected into the exhaust pipe, in front of the SCR catalyst, downstream of the engine. Heated in the exhaust it decomposes into ammonia and CO2.   When the NOx reacts inside the catalyst with the ammonia, the harmful NOx molecules in the exhaust are converted to harmless nitrogen and water.
For the correct functioning of your SCR system, make sure you use only high quality AdBlue in combination with high quality AdBlue pumping equipment such as Blue1.  SCR is already a proven technology and one which will be relied on in the future. It will be used for the forthcoming Euro VI standard.

Legislation

There are different emission standards around the world, setting specific NOx emission limits that require the use of SCR and AdBlue. The four main pollutants covered by vehicle emission legislation are Oxides of Nitrogen (NOx), Particulate Matter (PM), Carbon monoxide (CO), and Hydrocarbons (HC).
In Europe, the first of these Standards, Euro 0, came into effect in 1990 with NOx limits of 14.4 and PM limits of 1.1, both measured in g/kwh.  The 2001 Euro III standard reduced these limits to 5 and 0.1 respectively. The use of AdBlue came with the introduction of Euro IV, V and VI standards. NOx, particulate matter (PM), hydrocarbons (HC) and carbon monoxide (CO) are the components regulated. Euro IV was implemented from Oct. 2005 to Oct. 2006 and Euro V implementation dates were from Oct. 2008 to Oct. 2009. The Emissions limit for NOx is 3.5 g/kWh in Euro IV and 2.0 g/kWh in EuroV. Euro VI standard will be implemented as from 2013-14 and will have a NOx limit of 0,4 g/kWh.
In the USA, emissions from vehicles are regulated by the Clean Air Act. The use of urea SCR NOx control is coming to the US with the implementation of the so-called US2010 emission standard, which is effective as of January 1st 2010 and sets the NOx emission limits at 0,3 g/kWh.
In Australia and New Zealand, the emission standards follow those of Europe with a few years delay. Euro IV was phased in from 2007 and Euro V will be implemented in 2010.
In China, the legislation is called National Standard IV and V. From 2008, National VI standard for heavy duty vehicles has reduced NOx limits to 3,5 g/kWh and PM limits to 0,02 g/kWh. This standard has been applied in Beijing since 2008.
In Brazil, the legislation is called PROCONVE - Programa de Controle da Poluição do Ar por Veículos Automotores and will be applied as from 2012. The reagent in Brazil is known as ARLA 32 and this acronym stands for Agente Reductor Liquido Automotivo.
