The properties specified in the EN590 include: Centane number: a minimum of 51 Centane index: a minimum of 46 Polycyclic aromatic hydrocarbons: a maximum of 11% Water content: a maximum of 200 ppm Flash point: a minimum of 55 C Ash content: a maximum of 0.01% Viscosity at 40 degrees celsius: a minimum of 2 cst, and a maximum of 4.5 cst Density at 15 degrees celsius: a minimum of 820 Kg/m3, and a maximum of 845 Kg/m3 Total contamination: a maximum of 24 ppm Sulphur content: a maximum of 10 ppm Lubricity at 60 degrees celsius: a maximum of 460 microns Carbon residue: a maximum of 0.3% Copper strip corrosion for 3 hours at 50 degrees celsius: must have a Class 1 rating Oxidation stability: a maximum of 25 g/m3 Cloud point: the low temperature at which the wax in diesel begins to turn cloudy as it solidifies. This solidification of the wax thickens the oil, resulting in the fuel clogging the fuel filters and fuel injectors and fuel additive injectors in vehicle engines. CFFP - Cold filter plugging point: the minimum temperature at which the fuel can still flow through a filter FAME (Fatty Acid Methyl Esters) content of the bio-part
D2 is a refinery abbreviation for Gasoil. It is the second distillate from the crude, and can be used without reformers and additives. So, the first engines used D2 as fuel before petrol cars as we know them today was invented. That is because the engine invented by a German called Diesel, requires no spark plugs.
D6 is a type of residual fuel, mainly used in power plants and larger ships. The fuel is required to be preheated before it can be used. It is not possible to use it in smaller engines or vessels/vehicles where it is not possible to pre-heat it. D6 is its name in the USA. In other parts of the world it has other names. Number 6 fuel oil is a high-viscosity residual oil requiring preheating to 220 - 260 F (104 - 127 C).
D6 BUNKER FUEL OIL D6 is also known as Residual Fuel Oil and is of high-viscosity. This particular fuel oil requires preheating to 220 - 260 Degrees Fahrenheit. D6 is mostly used for generators. D6 is a type of residual fuel, mainly used in power plants and larger ships. The fuel requires to be preheated before it can be used. It is not possible to use it in smaller engines or vessels/vehicles where it is not possible to pre-heat it. D6 is its name in the USA. In other parts of the world it has other names.
