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 ...
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 ...
Grade 2 diesel fuel 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.
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 ...
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 ...

A diesel cycle engine can be as much as 40% to 50% efficient at converting fuel into work, [2] where a typical automotive gasoline engine's efficiency is about 25% to 30%. [3] [4] In general, an engine is designed to run on a single fuel source and substituting one fuel for another may affect the thermal efficiency.
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 .
