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.

超低硫柴油 是一種較低 硫 含量的 柴油 燃料。 2006年間，幾乎所有於歐洲和北美供應的從石油提煉的柴油都是超低硫柴油。 各國政府對其規格並不一致，但均傾向逐步收緊。 硫的含量越低，柴油引擎才能使用更新型的減排技術，使懸浮粒子的排放降低。 基於上述原因， 歐盟 首先推行，隨後 北美洲 各國亦跟隨。 新排放標準取決於更潔淨的燃料，2007年開始 美國 新生產汽車開始執行這個標準。 超低硫柴油能量較低，因為當中需要很多能量去除石油中的硫，燃料效益較低， …

2024年8月15日 · Beginning in 2006, EPA began to phase-in more stringent regulations to lower the amount of sulfur in diesel fuel to 15 ppm. This fuel is known as ultra-low sulfur diesel (ULSD). EPA’s diesel standards target emissions from two different sources: Nonroad engines and …

ULSD is a cleaner-burning diesel fuel that contains 97% less sulfur than low-sulfur diesel (LSD). ULSD was developed to allow the use of improved pollution control devices that reduce diesel emissions more effectively but can be damaged by sulfur.

超低硫化柴油(ulsd)是一种硫含量大大降低的柴油。 自2006年以来，几乎所有在欧洲和北美可用的石油基柴油都是ULSD类型。 降低硫含量的举措允许应用先进的排放控制技术，大大降低柴油燃烧产生的有害排放物。

2021年5月6日 · As implied by the name, Ultra Low Sulfur Diesel (ULSD) is a variant of traditional or "normal" diesel fuel that is mostly stripped of its sulfur content. Why Does Ultra Low Sulfur Diesel Exist? In a nutshell, ULSD was created in response to a number of regulatory actions aimed at reducing diesel fuel emissions:

To meet EPA standards, the petroleum industry is producing Ultra Low Sulfur Diesel (ULSD) fuel, a cleaner-burning diesel fuel containing a maximum 15 parts-per-million (ppm) sulfur. In combination with cleaner-burning diesel engines and vehicles, ULSD fuel will help to improve air quality by significantly reducing emissions.

2024年5月24日 · Explore the fascinating history behind the emergence of ULSD, its impact on combustion engine operations and how it stacks up against other fuels. What Is ULSD and Why Does it Exist? Ultra-low sulfur diesel is a diesel fuel with a significantly lower sulfur content of 15 parts per million (ppm) or less. This makes it around 97% cleaner than ...

2017年1月19日 · Beginning in 2006, EPA began to phase-in more stringent regulations to lower the amount of sulfur to 15 ppm. This fuel is known as ultra-low sulfur diesel (ULSD). EPA’s diesel program standards require that: These standards reduce harmful emissions from highway vehicles and nonroad engines and equipment by more than 90%.
