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.

2024年8月15日 · From 2007 to 2014, low sulfur diesel fuel (specified at 500 ppm) and ULSD fuel was phased in for nonroad, locomotive, and marine (NRLM) diesel fuel. After 2014, EPA’s diesel standards require that: All nonroad, locomotive, and marine (NRLM) diesel fuel …

2023年10月14日 · Ultra-Low Sulfur Diesel (ULSD) is a type of diesel fuel that has substantially lower sulfur content compared to traditional diesel. The transition to ULSD was driven primarily by environmental concerns, as sulfur emissions from diesel engines can contribute to air pollution and health issues.

2025年2月22日 · Ultra low sulfur diesel is a type of fuel that contains significantly lower sulfur concentration compared to traditional diesel. The reduction of sulfur content in this fuel allows to reduce the emission of sulfur dioxide (SO₂), a compound harmful to health and the environment.

2022年9月14日 · In 2006, the EPA began lowering the standard to 15 ppm sulfur for on-road diesel, creating the “ultra-low sulfur diesel” category. The transition for off-road equipment, locomotives, and marine fuel came in 2007. By 2010, virtually all low sulfur diesel had been transitioned out of production, and ULSD became the dominant product on the market.

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.

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.

2016年5月31日 · Ultra-low sulfur diesel is a cleaner burning diesel fuel that has a sulfur content that is about 97% less than that of low sulfur diesel fuel. ULSD is supposedly safe to use on older diesel engines, but there are some disputes about this due to the change in certain naturally occurring chemical components that aid lubricity, among other issues.

2024年5月24日 · 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 conventional on-road low-sulfur diesel (LSD), which contains an average of 500 ppm sulfur.

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%.
