From January 1st 2005, vehicles produced in Europe will have needed to meet even tighter emissions standards, namely Euro 4.
In order to meet the new standards, all heavy good vehicles need to reduce the amount of NOx (Nitrous Oxides) they emit.
Euro 5 is nearly upon us and is scheduled for introduction in October 2009. The new limits outlined in Euro 5 are even more stringent than before, in fact almost half of the previous standard.
Vehicle manufacturers are opting for SCR (Selective Catalytic Reduction) as the preferred technology to meet the demands set out by Euro 5. This involves incorporating the urea into an aqueous solution called AdBlue. The alternative is EGR (Exhaust Gas Recirculation) but this technology has its limits and at present will not be able to meet the demands of Euro 6 due in 2012
There are a number of advantages with SCR technology as around 85% of the nitrous oxide is converted into water vapour and nitrogen. (the air we all breath is approximately 74% nitrogen). In addition to this fuel savings of up to 6% have been boasted by some of the leading vehicle manufacturers. This has encouraged many of the leading manufacturers to concentrate their efforts on developing SCR vehicles in their range. With fuel pump prices now at a record high, support for SCR is growing fast.
Concern has been identified at the outset though as AdBlue is highly susceptible to contamination unless handled correctly, which has led to some dispute surrounding the creation of new ISO standards, who should be involved and how should they be implemented.
At present the AdBlue solution is produced in Europe and shipped to the UK, although there are plans to create production plants in the UK none are available to date.
With this import requirement and considering the sensitive handling aspects of the solution, sceptics fear that this technology may never really settle into the UK market.
However unless an alternative cleaner fuel solution is made available before October next year all modern fleet operators will have to adopt this new technology sooner or later.
The transport industry are encouraging the authorities to develop new standards to help guide consumers through this new technology.
