  2. Cetane number - Wikipedia

    en.wikipedia.org/wiki/Cetane_number

    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 ...

  3. Conradson carbon residue - Wikipedia

    en.wikipedia.org/wiki/Conradson_Carbon_Residue

    For burner fuel, Concarbon provides an approximation of the tendency of the fuel to form deposits in vaporizing pot-type and sleeve-type burners. [ 4 ] For diesel fuel , Concarbon correlates approximately with combustion chamber deposits, provided that alkyl nitrates are absent, or if present, that the test is performed on the base fuel without ...

    For burner fuel, MCR provides an approximation of the tendency of the fuel to form deposits in vaporizing pot-type and sleeve-type burners. [ 5 ] For diesel fuel , MCR correlates approximately with combustion chamber deposits, provided that alkyl nitrates are absent, or if present, that the test is performed on the base fuel without additive.

    The largest share of oil products is used as "energy carriers", i.e. various grades of fuel oil and gasoline. These fuels include or can be blended to give gasoline, jet fuel, diesel fuel, heating oil, and heavier fuel oils.

  6. Winter diesel fuel - Wikipedia

    en.wikipedia.org/wiki/Winter_diesel_fuel

    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 ...

  7. Cetane index - Wikipedia

    en.wikipedia.org/wiki/Cetane_index

    Cetane index is used as a substitute for the cetane number of diesel fuel. The cetane index is calculated based on the fuel's density and distillation range (ASTM D86). There are two methods used, ASTM D976 and D4737. The older D976, or "two-variable equation" is outdated and should no longer be used for cetane number estimation.
