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 ...
Sale of Grade 1 diesel is optional at retail outlets. Grade 2, also known as GASOIL COMUN (common diesel fuel), is intended for the bulk of diesel fuelled vehicles. Grade 2 diesel fuel is available with 2 different sulfur levels depending on the population density of the location where it is retailed.
Due to the higher density, diesel fuel offers a higher volumetric energy density: the density of EN 590 diesel fuel is defined as 0.820 to 0.845 kg/L (6.84 to 7.05 lb/US gal) at 15 °C (59 °F), about 9.0-13.9% more than EN 228 gasoline (petrol)'s 0.720–0.775 kg/L (6.01–6.47 lb/US gal) at 15 °C, which should be put into consideration when ...
North American distillate is broadly described as a fuel with heavier molecular weight than gasoline, and similar to or lighter than kerosene or No. 1 fuel oil. However, both usage of the term and formulation of the product varied widely. Octane ratings varied similarly, between 33 and 45. [1] [2]
This fuel is commonly known as diesel no. 1, kerosene, and jet fuel. Former names include: coal oil, stove oil, and range oil. [7] Number 2 fuel oil is a distillate home heating oil. [8] Trucks and some cars use similar diesel no. 2 with a cetane number limit describing the ignition quality of the fuel. Both are typically obtained from the ...
The gel point of petroleum products is the temperature at which the liquids gel so they no longer flow by gravity or can be pumped through fuel lines. This phenomenon happens when the petroleum product reaches a low enough temperature to precipitate interlinked paraffin wax crystals throughout the fluid.
Alpha-methylnaphthalene, which has a long delay period, was assigned a cetane number of 0, but has been replaced as a reference fuel by 2,3,4,5,6,7,8-heptamethylnonane, which is assigned a cetane number of 15. [2] All other hydrocarbons in diesel fuel are indexed to cetane as to how rapidly they ignite under compression, i.e. diesel engine ...
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).
