Ultra-low-sulfur diesel ( ULSD ) is diesel fuel with substantially lowered sulfur content. Since 2006, almost all of the petroleum-based diesel fuel available in Europe and North America has been of a ULSD type.
66-412: The move to lower sulfur content allows for the application of advanced emissions control technologies that substantially lower the harmful emissions from diesel combustion. Testing by engine manufacturers and regulatory bodies have found the use of emissions control devices in conjunction with ULSD can reduce the exhaust output of ozone precursors and particulate matter to near-zero levels. In 1993
132-452: A low-melting eutectic alloy that can increase lubricity. The process used to reduce the sulfur also reduces the fuel's lubricating properties. Lubricity is a measure of the fuel's ability to lubricate and protect the various parts of the engine's fuel injection system from wear. The processing required to reduce sulfur to 15 ppm also removes naturally occurring lubricity agents in diesel fuel. To manage this change ASTM International (formerly
198-458: A 15 ppm sulfur content was originally set for July 15, 2006 for distribution terminals, and by September 1, 2006 for retail. But on November 8, 2005, the deadline was extended by 1.5 months to September 1, 2006 for terminals and October 15, 2006 for retail. In California, the extension was not granted and followed the original schedule. As of December, 2006, the ULSD standard has been in effect according to

From the year 1992, production started of a diesel fuel with 2 to 5 ppm of sulfur and a maximum of 5% by volume aromatics. There are certain tax incentives for using this fuel and from about year 2000, this low aromatic, low sulfur fuel has achieved 98-99% penetration of the Swedish diesel fuel market. Now RME (rapeseed methyl ester, also known as FAME (Fatty Acid Methyl Ester))
462-575: A tax incentive of per litre of "sulfur free" fuel (both gasoline and diesel) containing less than 10 ppm beginning in January 2003 and average sulfur content was estimated in 2006 to be 3-5 ppm. Similar measures have been enacted in most of the Nordic countries , Benelux , Ireland and the United Kingdom to encourage early adoption of the 50 ppm and 10 ppm fuel standards. Since 1990, diesel fuel with

The vapors are adsorbed within the canister, and during certain engine operational modes fresh air is drawn through the canister, pulling the vapor into the engine, where it burns. Some US states are also using a technology which uses infrared and ultraviolet light to detect emissions while vehicles pass by on public roads, thus eliminating
660-536: Is a biofuel additive. Since 2003, a "zero" sulfur with very low aromatic content (less than 1% by volume) diesel fuel has been made available on the Swedish market under the name EcoPar . It is used wherever the working environment is highly polluted, an example being where diesel trucks are used in confined spaces such as in harbours, inside storage houses, during construction of road and rail tunnels & in vehicles that are predominantly run in city centres. As of 2008, most accession countries are expected to have made

Various exceptions exist for certain uses and applications, most of which are being phased out over a period of several years. In particular, the so-called EU accession countries (primarily in Eastern Europe ), have been granted certain temporary exemptions to allow for transition. Certain EU countries may apply higher standards or require faster transition. For example, Germany implemented
858-447: Is available with 2 different sulfur levels depending on the population density of the location where it is retailed. Grade 3 diesel fuel, also known as GASOIL ULTRA, is the highest quality diesel fuel and is supposed to be available starting February 1, 2006. Sale of Grade 3 diesel at retail outlets is optional until 2008. At the time the regulation was published, the sulfur limits amounted to 3000 ppm for Grade 1, 1500/2500 ppm (depending on

The production and distribution of unleaded fuel was a major challenge, but it was completed successfully in time for the 1975 model year cars. All modern cars are now equipped with catalytic converters to further reduce vehicle emissions. Leading up to the 1981 model year in the United States, passenger vehicle manufactures were faced with
1188-809: The American Petroleum Institute , the domestic refining industry has invested over $ 8 billion to comply with the new regulations. ULSD runs in any engine designed for the ASTM D975 diesel fuel, however, it is known to cause some seals to shrink, and may cause fuel pump failures in Volkswagen TDI engines used in 2006 to pre-2009 models. TDI engines from 2009 and on are designed to use ULSD exclusively; biodiesel blends are reported to prevent that failure. Some filling stations in Kenya started offering 50 ppm diesel as of December 2010. As of 2018, Kenya has not fully implemented emission control systems. As of June 2012, 50 ppm diesel

Emissions tests on diesel cars have not been carried out during MOTs in Northern Ireland for 12 years, despite being legally required. It was very important to system designers to meet the emission requirements using a minimum quantity of catalyst material ( platinum and/or palladium ) due to cost and supply issues. The General Motors "Emissions Control Systems Project Center"
1320-498: The European Union began mandating the reduction of diesel sulfur content and implementing modern ULSD specifications in 1999. 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. Sulfur is not a lubricant in and of itself, but it can combine with the nickel content in many metal alloys to form
1386-436: The European Union , the “Euro IV” standard has applied since 2005, which specifies a maximum of 50 ppm of sulfur in diesel fuel for most highway vehicles; ultra-low-sulfur diesel with a maximum of 10 ppm of sulfur must “be available” from 2005 and was widely available as of 2008. In 2009, the Euro V fuel standard came into effect which reduced maximum sulfur to 10 ppm. In 2009, diesel fuel for most non-highway applications

2046-922: The U.S. EPA. Mexico began introduction of ULSD throughout the country in 2006. Ultra-low-sulfur diesel fuel was proposed by EPA as a new standard for the sulfur content in on-road diesel fuel sold in the United States since October 15, 2006, except for rural Alaska which transferred in 2010. California has required it since September 1, 2006. This new regulation applies to all diesel fuel, diesel fuel additives and distillate fuels blended with diesel for on-road use, such as kerosene. Since December 1, 2010, all highway diesel fuel nationwide has been ULSD. Non-road diesel engine fuel moved to 500 ppm sulfur in 2007, and further to ULSD in 2010. Railroad locomotive and marine diesel fuel moved to 500 ppm sulfur in 2007, and changed to ULSD in 2012. There were exemptions for small refiners of non-road, locomotive and marine diesel fuel that allowed for 500 ppm diesel to remain in
