The EN 590 had been introduced along with the European emission standards.With each of its revisions the EN 590 had been adapted to lower the sulphur content of diesel fuel – since 2007 this is called ultra-low-sulphur diesel as the former function of sulphur as a lubricant is absent (and needs to be replaced by additives).
In 1993 the European Union began mandating the reduction of diesel sulfur content and implementing modern ULSD specifications in 1999. [ 3 ] [ 4 ] The United States started phasing in ULSD requirements for highway vehicles in 2006, with implementation for off-highway applications, such as locomotive and marine fuel, beginning in 2007.
In the 1990s specifications allowed a content of 2000 ppm max of sulfur, reduced to a limit of 350 ppm by the beginning of the 21st century with the introduction of Euro 3 specifications. The limit was lowered with the introduction of Euro 4 by 2006 to 50 ppm (ULSD, Ultra Low Sulfur Diesel). The standard for diesel fuel in force in Europe as of ...
Through different taxation the offered diesel fuel generally follows the extended specifications of the Swedish standard. [31] Circle-K provider delivers winter diesel with a CFFP of –32 °C the whole year. [31] The OKQ8 company offers two types depending on the region with currently two areas separated by the Dalälven river at 60° north ...
Neste MY Renewable Diesel (formerly NExBTL) is a vegetable oil refining fuel production process commercialized by the Finnish oil and refining company Neste.Whether as an admixture or in its pure form, the fuel is able to supplement or partially replace conventional diesel without problems.
In the European Union, emissions of nitrogen oxides (NO x), total hydrocarbon (THC), non-methane hydrocarbons (NMHC), carbon monoxide (CO) and particulate matter (PM) are regulated for most vehicle types, including cars, trucks (lorries), locomotives, tractors and similar machinery, barges, but excluding seagoing ships and aeroplanes.
The cetane number of a fuel is defined by finding a blend of cetane and isocetane with the same ignition delay. Cetane has a cetane number defined to be 100, while isocetane's measured cetane number is 15, replacing the former reference fuel alpha-methylnaphthalene, which was assigned a cetane number of 0.
A Publicly Available Specification or PAS is a standardization document that closely resembles a formal standard in structure and format but which has a different development model. [1] The objective of a Publicly Available Specification is to speed up standardization.
