EN590 Diesel | ULSD
28/2/23, 10:00 pm
EN 590 is a crucial standard for diesel fuel in Europe and other countries. It's been pivotal in reducing sulfur content, leading to the production of ultra-low-sulfur diesel (ULSD). This shift has been essential for mitigating emissions from diesel engines, particularly in densely populated urban areas. The transition to ULSD has been accompanied by the implementation of stricter emissions standards, such as Euro IV and Euro V, which have progressively lowered the permissible sulfur content in diesel fuel. The various measures taken by different countries within the European Union to accelerate the adoption of cleaner diesel fuels, including tax incentives and earlier implementation of stricter standards. These initiatives reflect a broader commitment to environmental sustainability and public health.
EN590 sets the standards for automotive diesel fuel in the European Union, Croatia, Iceland, Norway, and Switzerland. Its revisions have progressively lowered sulfur content, resulting in ultra-low-sulfur diesel (ULSD) since 2007.
QUALITY STANDARDS
European diesel fuels adhere to EN590 specifications, ensuring compatibility with diesel engines. Different grades are available to suit various climates, with all meeting Euro 4 and Euro 5 vehicle requirements. Low sulfur content reduces sulfur oxide emissions, crucial for urban air quality.
ULTRA-LOW-SULFUR DIESEL (ULSD)
ULSD, prevalent in Europe and North America since 2006, boasts substantially reduced sulfur content. This transition facilitates the adoption of advanced emissions control technologies, vital for reducing particulate matter emissions. However, ULSD's heavy processing leads to lower fuel economy and increased production costs.
EUROPEAN UNION STANDARDS
Euro IV and Euro V standards, enforced since 2005, mandate maximum sulfur levels in diesel fuel. ULSD with a sulfur content of 10 ppm became widely available in 2008, with further reductions to 10 ppm finalized in 2009 under Euro V. Various exceptions and transition periods exist, with some EU countries implementing higher standards or faster transitions through measures like tax incentives.
