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 the American Society for Testing and Materials) adopted the lubricity specification defined in ASTM D975 [6] for all diesel fuels and this standard went into effect January 1 ...
Neste guarantees that every gallon sold meets ASTM D975 and EN 15940 specifications in compliance with OEM standards. [1] Despite the former name BTL, the feedstock is vegetable oil and waste animal fats, not whole plants. However, fuel quality is equal to the synthetic Fischer-Tropsch BTL and GTL diesel fuels.
In North America, gas stations offer two types of diesel fuel – according to ASTM D975 [5] these are named No. 1 and No. 2 fuel. No. 1 fuel (similar to kerosene) has a natural CFPP of -40 °C but it is more expensive than No. 2 fuel. Adding No. 1 fuel will lower the CFPP of No. 2 fuel – adding 10% will lower the CFPP temperature by about 5 ...
Generally, diesel engines operate well with a CN from 40 to 55, whereas LS9 UltraClean has a CN of 70. In North America, most states adopt ASTM D975 as their diesel fuel standard and the minimum cetane number is set at 40, with typical values in the 42-45 range. In Europe, with a minimum cetane index of 46 and a minimum cetane number of 51.
In Europe, diesel cetane numbers were set at a minimum of 38 in 1994 and 40 in 2000. The standard for diesel sold in European Union, Iceland, Norway and Switzerland is defined by standard EN 590. Since 1 January 2001 EN 590 demands a minimum cetane index of 46 and a minimum cetane number of 51. Premium diesel fuel can have a cetane number as ...
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).
On the other hand, biomass-based diesel fuels that meet ASTM standards could be used in much higher concentrations than biodiesel, which is usually limited to 20% biodiesel blends for standard diesel vehicles. Considering those comments, the FTC decided to set separate labeling requirements for biodiesel blends and biomass-based diesel fuel blends.
Diesel fuel has many colloquial names; most commonly, it is simply referred to as diesel.In the United Kingdom, diesel fuel for road use is commonly called diesel or sometimes white diesel if required to differentiate it from a reduced-tax agricultural-only product containing an identifying coloured dye known as red diesel.
