AdBlue Wiki Entry - Adblue decay and contamination

AdBlue is the registered trademark for AUS32 (Aqueous Urea Solution 32.5%) and is used in a process called selective catalytic reduction (SCR) to reduce emissions of oxides of nitrogen from the exhaust of diesel engined motor vehicles.
As the name AUS32 would suggest, it is a 32.5% solution of high-purity urea in demineralized water that is clear, non-toxic and is safe to handle. However, it can be corrosive for some metals, and must be stored and transported using the correct materials. 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.^[1]
AdBlue is carried onboard SCR-equipped vehicles in specially designed tanks, and is dosed into the SCR system at a rate equivalent to 3–5% of diesel consumption. This low dosing rate ensures long refill periods and minimises the tank's impact on chassis space. On-highway SCR systems are currently in use throughout Europe, in Japan, Australia, Hong Kong, Taiwan, Korea, New Zealand and Singapore. The United States Environmental Protection Agency‎'s (US EPA) 2010 legislation will limit NOx to levels that will require North American trucks to be equipped with SCR post-2010. The current generic name in North America for AUS32 is diesel exhaust fluid (DEF). Some trucking industry OEMs have already developed branded SCR solutions, such as Daimler's BlueTec.
All European truck manufacturers currently offer SCR equipped models, and the future Euro6 emission standard is set to reinforce the demand for this technology. SCR systems are sensitive to potential chemical impurities in the urea solution, therefore, it is essential to maintain high standards of AdBlue quality according to the ISO 22241 standard.
The use of SCR technology in Europe made it necessary to develop an AdBlue supply infrastructure. AdBlue is available from thousands of service stations, this locator finder is updated monthly with new Retail sites selling AdBlue. It can also be purchased in canisters of 5 or 10 litres at service stations. Larger quantities of AdBlue can be delivered in, for example, 208 litres (46 imp gal; 55 US gal) drums, 1,000 litres (220 imp gal; 260 US gal) intermediate bulk container (IBCs), and bulk.

Costly Adblue Contamination Error for UK Haulier

During the past few weeks a large northern fleet operator discovered that their new Fleets NOx reduction system had become polluted.

The failed SCR injector had been polluted with oil.

The following investigation identified that the problem was caused by an operator using a non-dedicated container to transfer AdBlue from the IBC to the vehicle.  

The operative admitted to using a non approved-adblue container which had previously been used to top up engine oil and antifreeze and despite receiving a ‘quick rinse’ had led to contamination of the lines. Fortunately, the new magnum was the only truck to have received AdBlue from this container.

To confirm, AdBlue is highly susceptible to contamination and as little as 10ml of oil present in a 100 litre fill can corrupt the system causing irreversible damage.

adblue cure contamination

It only takes 5ml of diesel to 20 litres of AdBlue in the AdBlue tank to turn it into a harmful useless paste.  A problem that is any vehicles worst nightmere.  The first advice we would offer you is to not attempt to drive away.

In order to comply with new emission standards, the automobile industry has decided to introduce SCR technology to diesel -powered vehicles.

In nearly all cases the insurance industry will not pay out for misfuelling cases.

Thge AdBlue misfuelling cap has a build it system (including AdBlue magnet) which only opens when the AdBlue nozzle is inserted.

Adblue® Contamination - The Facts

New legislation regarding emission limits have been set by the EU. These new exhaust limits come into force in 2005 (EURO4) and in 2008 (EURO5).  The limits are set out in several EU Directives, including 88/77/EEC, 1999/96/EC and 2001/27/EC.

Selective Catalytic Reduction (SCR) and AdBlue® has been selected by the vehicle manufactures.  It has been selected as a solution to help with the diesel emissions.

AdBlue® was introduced to heavy-duty vehicles over 3.5 tonnes to reduce the nitrogen oxide emissions (N0x).  Adblue® usage amounts to approx. 3-4% of the fuel consumption on EURO4 vehicles.  A typical heavy-duty vehicle will consume approx. 3 tonnes of AdBlue per year.

Although AdBlue® is considered non-hazardous it presents several probloems during storage and handling on a day to day basis.

AdBlue®:

quickly crystallises when exposed to air
It freezes at - 11 degrees C
It has a corrosive effect on some common metals
It should be protected from contamination.
It should not be released freely into the environment.

These properties require that AdBlue is handled with care.  Any equipment coming into contact must be of suitable material.

Dispensing systems must minimise contact with air to prevent crystallisation, provide protection from the cold and prevent spillage. 

AdBlue Requires a Sealed Connection
To ensure AdBlue can be handled in a reliable and safe way, IDENTIC have developed a sealed dispensing system for refilling AdBlue on vehicles.  This spill-free vehicle refilling system provides the following advantages.

1/  Prevents the risk of spillage, crystallisation and corrosion on the vehicle and the filling point.

2/  Ensures only AdBlue can be filled in the vehicles AdBlue tank preventing the risk of permanent damage to the SCR equipment.

3/  Protects the quality of the AdBlue, preventing the risk of AdBlue® contamination and maintaining the vehicle emission standards it is designed to achieve.

AdBlue® misfuelling; the facts

Replacement of dosing, SCR and CAT units.

To prevent cross contamination we offer the worldwide patented AdBlue® Misfuelling Cap which only allows a 19MM gun entry.  Our solution comes with the AdBlue® magnet inbuilt.

The protection system consists of a ready mounted adapter that has been designed for the different sizes in adblue tanks.  The refilling neck comes in two diameters (58 and 77 mm).
We offer a cap solution for each diameter.

Only the correct AdBlue® refill pistol will fit into the opening - No access for diesel, gas, other pistols or contaminants.

For additional safety, there is a flap on the inside, which closes the opening.  It can be opened by the AdBlue® refill pistol.  The intergrated magnet releases the inserted AdBlue® refill pistol to refill the tank.  The upper part of the lid, fastened on a rubber band, closes the tank.

wrong liquid in adblue - misfuel advice

The AdBlue^®/DEF, which is used on diesel powered vehicles in order to clean the exhaust gases with SCR technology (Selective Catalytic Reduction), has some special characteristics which have to be considered.

The fluid crystallizes when in contact with air and causes corrosion when in contact with some common metals and other materials. For a correct function of the SCR technology it is important that the chemical is not contaminated, and in order to prevent that refilling is done in the wrong tank the refilling inlet has been designed and standardised according to ISO standards

• Prevents the risk for spillLess risk for spills and corrosion.
• Only AdBlue^®/DEF can be refilled in the tankPrevents wrong fluid to be filled in the AdBlue^®/DEF tank, which could cause serious damage to the SCR system
• Can be retrofitted
  The equipment can be retrofitted on existing vehicles

Iveco announces Euro VI engine line up with no EGR

Iveco and Fiat Powertrains have announced a Euro VI engine line which meets the emissions standards without using Exhaust Gas Recirculation (EGR). Instead the new engine range relies on Selective Catalytic Reduction (SCR) and a Diesel Particulate Filter (DPF) to meet NOx limits.
Fiat Powertrains' (FTP) new SCR technology will be introduced onto the new Cursor and Tector engine ranges for heavy-duty trucks and buses.
Alfredo Altavilla, Iveco Chief Executive Officer, said: "The technology that reduces fuel consumption and additional operating costs to their minimum is the correct technical choice. FPT Industrial's 'SCR Only' exhaust after-treatment fulfils this important need.
"It is clear that Euro VI vehicles will be more expensive; technology has a price and a value. We will introduce suitably equipped vehicles when our customers ask us to do so."
The new technology includes the following features, according to FTP:
• Optimised fluid-dynamics modelling of exhaust gas and AdBlue injection on SCR catalysts.• Feed forward control logic to enable precise AdBlue dosing in order to abate incoming sensed NOx emissions.
• Ammonia and NOx sensor technology for extremely accurate exhaust gas sensing, enabling adaptive AdBlue dosing to compensate for any ageing of the SCR catalyst.
• Insulated tube turbulence mixer technology to allow a homogeneous urea hydrolysis and distribution in the exhaust gas stream by introducing a swirling motion.
Euro VI emissions norms will apply to heavy-duty vehicles from the from 1st January 2014
