Jet fuel, Aviation Turbine Fuel (ATF), or Avtar , Aviation Turbine Fuel (ATF), or vtur 

 is a type of fuel designed for use in aircraft powered by gas-turbine engines. It is clear to straw-coloured in appearance. The most commonly used fuels for commercial aviation are Jet A and Jet A-1 which are produced to a standardized international specification. The only other jet fuel commonly used in civilian turbine-engine powered aviation is Jet B which is used for its enhanced cold-weather performance.

Aviation Fuel or Jet fuel is a mixture of a large number of different hydrocarbons. Kerosene-type jet fuel (including Jet A and Jet A-1) has a carbon number distribution between about 8 and 16 carbon numbers (carbon atoms per molecule); wide-cut or naphtha-type jet fuel (including Jet B), between about 5 and 15 carbon numbers.

Aviation fuel or Jet Fuel is a specialized type of petroleum-based fuel used to power aircraft; it is generally of a higher quality than fuels used in less critical applications such as heating or road transport, and often contains additives to reduce the risk of icing or explosion due to high temperatures, amongst other properties.

Ultra-low-sulfur diesel (ULSD)

 is diesel fuel with substantially lowered sulfur content. Since 2006, almost all of the petroleum-based diesel fuel available in Europe and North America has been of a ULSD type.

The move to lower sulfur content allows for the application of advanced emissions control technologies that substantially lower the harmful emissions from diesel combustion. Testing by engine manufacturers and regulatory bodies have found the use of emissions control devices in conjunction with ULSD can reduce the exhaust output of ozone precursors and particulate matter to near-zero levels.

 EN590 describes the physical properties that all automotive diesel fuel must meet if it is to be sold in the European Union, Croatia, Iceland, Norway and Switzerland.

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).

The quality of European diesel fuels is specified by the EN 590 standard. While these specifications not are mandatory, they are observed by all fuel suppliers in Europe.

Automobile diesel en 590 is intended for application in diesel engines. Diesel motor fuel quality meets the requirements of European Standard EN 590. For operation in the conditions of a temperate climate following marks of fuel diesel automobile EN 590 are offered: Grade C - limiting filterability temperature -5 ° C; Grade D - limiting filterability temperature -10 ° C; Grade E - limiting filterability temperature - 15 ° C; Grade F - limiting filterability temperature -20 ° C. The entire volume of produced diesel fuel quality meets the requirements for fuels for vehicles of Euro 4 and Euro 5. Low sulfur content in diesel  EN 590 reduces emissions of sulfur oxides into the atmosphere, which is especially important for for inhabitants of big cities.

 ALSO KNOWN AS VIRGIN FUEL OIL/ RESIDUAL FUEL OIL/ BUNKER OIL

D6 Diesel is also known as Residual Fuel Oil / Bunker Fuel Oil , Bunker 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.

Residual means the material remaining after the more valuable cuts of crude oil have boiled off. The residue may contain various undesirable impurities including 2 percent water and one-half percent mineral soil. D6 fuel is also known as residual fuel oil (RFO), by the Navy specification of Bunker C, or by the Pacific Specification of PS-400.

Recent changes in fuel quality regulation now require further refining of the D6 in order to remove the sulfur, which leads to a higher cost. Despite this recent change, D6 is still less useful because of its viscosity as well as that it needs to be pre-heated before it can be used and contains high amounts of pollutants, such as sulfur. Since it requires pre-heating, it cannot be used in small ships or boats or cars. However large ships and power plants can use the residual fuel oil.

The price of D6 diesel traditionally rises during colder months as demand for heating oil rises, which is refined in much the same way. In many parts of the United States and throughout the United Kingdom and Australia, D6 diesel may be priced higher than petrol.

D6 Diesel Standards and Classification

Saffron is a spice from the Crocus sativus flower, which is a cousin of the lily. The saffron derives from the stigma and styles — called threads — within the flower itself.

Saffron is very expensive due to the difficulty of harvesting it. Farmers must harvest the delicate threads from each flower by hand.

They then heat and cure the threads to bring out the flavor of the saffron
