OREANDA-NEWS. October 14, 2014. Neste Oil will introduce consumer packs of AdBlue - an aqueous urea solution used as a diesel exhaust fluid for reducing nitrous oxide (NOx) emissions - in October, to provide the product across whole Finland via largest service station network in the country.

 The new 1.89-liter packs will make it easy to use AdBlue in diesel cars. Up until now, AdBlue has only been sold in bulk and larger packs for heavy vehicles.

Under new Euro VI tailpipe emission regulations, all new cars type-approved after 1 September 2014 must comply with stricter tailpipe emission limits, which will apply to new cars registered and sold from fall 2015 onwards.

In the case of diesel vehicles, this will see the spread of AdBlue usage in medium-sized and large diesel cars and vans fitted with SCR (Selective Catalytic Reduction) units. The catalyst in SCR units uses AdBlue to reduce NOx content by converting the nitrous oxides in exhaust into nitrogen and water. The SCR system needs the urea solution to operate and, if the solution is not added, will limit engine performance.

AdBlue has been used, in combination with SCR, by trucks, buses, and other heavy vehicles for many years. The new 1.89-liter packs for consumers will be added to the product range on sale at Neste Oil's service stations in Finland and via distributors in October.
