the starting of 2005 Euro 4 became effective which necessitated all heavy merchandise vehicle manufacturers to ensure their new vehicles emit less noxious gases than before.
In array to meet the new standards, all massive good vehicles need to dilute the quantity of NOx (Nitrous Oxides) they ooze.
Euro 5 is telling as of October 2009. The new limits outlined in Euro 5 are even extra stringent than before, in fact about half of the previous standard.
Vehicle contractors are opting for SCR (Selective Catalytic Reduction) as the preferred technology to encounter the claims set out along Euro 5. This involves incorporating the urea into an aqueous solution cried AdBlue. The alternative is EGR (Exhaust Gas Recirculation) yet this technology has its limits and even now will no be capable to meet the demands of Euro 6 due in 2012
There are a digit of conveniences with SCR technology as nigh 85% of the nitrous oxide is converted into water vapour and nitrogen. (the atmosphere we all respiration is nearly 74% nitrogen). Fuel savings of approximately 6% tin be achieved using the SCR usage. This has encouraged many of the leading manufacturers to concentrate their exertions on amplifying SCR vehicles in their range. With fuel pump amounts immediately at a disc tall,[link widoczny dla zalogowanych], assist for SCR is growing rapid.
Concern has been identified at the outset though as AdBlue is extremely susceptible to contamination unless handled correctly, which has led to some discussion surrounding the production of new ISO standards, who ought be involved and how should they be implemented.
At present the AdBlue solution is produced in Europe and shipped to the UK, however there are maneuvers to establish production plants in the UK none are available by far.
Sceptics are using these attentions to quarrel the long term suitability of the AdBlue concept in the UK's Market.
However unless an alternative cleaner oil solution namely made available before October next annual all modern fleet operators ambition must accept this current technology sooner or after.
The transport industry feels the absence for new treatment criteria apt be introduced for presently as likely to adviser unfamiliar consumers through what is otherwise a quite precarious alteration in apt the direction colossal vehicles are refuelled.
