Protecting the Planet with Future Fuel Technologies

As of the 1st Jan 2005, virgin vehicles sold in Europe have needed to comply with the Euro 4 Emissions standard, this stage of the Euro's morals requires harmful emissions to be halved from the previous Euro 3 requirement. In order to meet the latest standards, all heavy skilled vehicles call for to reduce the amount of NOx (Nitrous Oxides) they emit. Euro 5 is effective as of October 2009. The modern limits outlined in Euro 5 are much more stringent than before, in naked truth almost half of the previous standard. Vehicle manufacturers are opting for SCR (Selective Catalytic Reduction) as the preferred technology to meet the demands allot gone by Euro 5. This involves incorporating the urea into an aqueous solution called AdBlue. The alternative is EGR (Exhaust Gas Recirculation) nevertheless 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 enclosing 85% o
f the nitrous oxide is converted into h2o vapour and nitrogen. (the air we all breath is approximately 74% nitrogen). Fuel savings of approximately 6% can be achieved using the SCR method. This has encouraged many of the leading manufacturers to concentrate their efforts on developing SCR vehicles in their range. With fuel pump prices promptly 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 original 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. Sceptics are using these considerations to argue the lenghty term suitability of the AdBlue concept in the UK's Market. However unless an alternative c
leaner fuel solution is made available before October closest year all modern fleet operators will have to adopt this advanced technology sooner or later. The transport industry are encouraging the authorities to develop recent standards to relieve guide consumers through this fresh technology.
