Gasoline D2 or Diesel D2 in Iran
A refinery abbreviation for Gasoil is Diesel D2 or Gasoline D2. Unlike crude distillate, it does not require reformers or additives for use. Before petrol cars as we know them today were invented, diesel engines used D2 as fuel. This is due to the fact that a German engine called Diesel requires no spark plugs. When pressure increases, the diesel engine will ignite and combust so that the heated “plug” explodes. As a result, diesel engines are based on the same principles. As a result, the refinery will add additives to the automotive diesel that you fill to make the engine more efficient and easier to start over the winter season.
The “Flash Point” of diesel changes in the winter, according to the small print. Like petrol, diesel also has additives to absorb water that condenses in the cylinder – but because the nozzles are injected directly into the cylinder, ice will destroy the nozzles before the engine. Your fuel pipes may freeze and burst if you use summer diesel in the winter, and the wax can make the diesel flow thicker. Summer diesel gives you better mileage, but you will have to deal with more fuel pipe freezing and bursts.
The role of sulfur in GASOIL and Diesel D2
It is the sulfur content of GASOIL and Gasoline D2 that makes them different. A limit of 4% sulfur in GASOIL was introduced by the US EPA 10 years ago, while Europe and the rest of the world followed later. Most of the time, when sulfur needs to be removed, ways of doing it more efficiently are quickly discovered. Sulfur can now be traded profitably with sulfuric acid, which is now motivating farmers to extract as much as possible.
In essence, ‘Low Sulphur Gasoil‘ is now below 0.2% rather than 4%. As for Ultra Low Sulphur, it has a maximum sulfur content of 0.02%, and there are two limitations here: (a) mass spectrographs need extensive calibration to measure below 1000ppm, and (b) sulfur can form clogs. As explained above, Diesel D2 is a distillate, and it has not been “cracked” by the refinery. As a result, the molecules bind to free hydrogen molecules, forming a cluster that will break. The average sulfur content in a barrel is less than 0.02%, so you only got a cluster of molecules in your pint of ULSG.
Oil companies standard for production Diesel D2
Oil companies use a standard for Gasoline D2 or Diesel D2 from the International Standardization Organization – ISO.
As a result of proposals from ASTM, API, and EPA, ANSI has defined the US national standard for Diesel D2.
There are national variants in Europe, for instance, DIN in Germany, and GOST in Russia.
According to the ISO standard, the GOST variant for D2/Gasoil has a maximum sulfur content of 0.02 MAX. As the ANSI standard, it calls it “Ultra Low Sulphur”, and 0,2% (2000ppm) will be referred to as “Low Sulphur”. Many cities have reduced their pollution as a result of the reduction of sulfur in their gasoil.
There are several national variants of automotive diesel, however, the most common variants traded are EN590, which is a specification from the ISO in Paris.
The EN590 and EN560 ISO for Gasoline D2 or Diesel D2
Diesel fuel sold in the European Union and Great Britain must meet physical properties referred to as D2 (Gasoline D2). It is common to trade automotive diesel variants conforming to EN590 and EN560, which are specified by ISO in Paris.
It has been almost 20 years since EN590 was introduced for diesel (in Europe). In addition to responding to legislation, fuel undergoes continual development, like most products. There have been many revisions to EN590 since 1993.
As part of the European emission standards, the Gasoline D2 or Diesel D2 had been introduced. Every time EN590 was revised, the sulfur content of diesel fuel was lowered. Due to the lack of sulfur as a lubricant (and the need for additives to replace it), this fuel is now known as ultra-low sulfur diesel.
In Europe, diesel fuel is regulated by the EN 590 standard. Despite not being mandatory, all European fuel suppliers adhere to these specifications. Diesel engines for automobiles are designed according to EN 590. In accordance with European Standard EN 590, diesel motor fuel meets all requirements.
TC19 (Working Group 24) of CEN specifies the maximum biodiesel content in EN590 diesel. A mandate from the European Commission (DG-TREN) has recently been issued to CEN for revision of EN590, allowing Biodiesel/FAME content of up to 10% v/v (8.8% energy content).
The following marks of fuel diesel automobile EN 590 are available for operation in temperate climates: Grade C – limiting filterability temperature of -5 ° C; Grade D – limiting filterability temperature of -10 ° C; Grade E – limiting filterability temperature of 15 ° C; Grade F – limiting filterability temperature of -20 ° C.
Diesel fuel produced in the factory meets the quality requirements for Euro 4 and Euro 5 vehicles. It is particularly important for residents of big cities to have low sulfur content in diesel EN 590 (Gasoline D2) in order to reduce sulfur oxide emissions into the atmosphere.
Revisions of the EN950 diesel Standard
The EN 590 standard has been revised in several important ways, including:
- First EU specification for diesel fuel – EN 590:1993. A sulfur limit of 0.2% was established for diesel fuels used on and off the road.
- Directive 98/70/EC specified a sulfur level of 350ppm and a cetane level of 51 by EN 590:1999.
- The Directive 2003/17/EC regulates sulfur limits of 50ppm (Euro 4) and 10ppm (Euro 5) in EN 590:2004. Five percent FAME (Fatty Acid Methyl Ester) in the food
- FAME content of 7% (B7) as regulated by Directive 2009/30/EC in EN 590:2009. Furthermore, the directive imposes a 10ppm sulfur limit on non-road fuels and mandatory biofuel requirements for refiners.
Gasoline D2 or Diesel D2 in Iran
In addition to being of high quality, Iran’s D2 Diesel Fuel is very competitive in price in comparison to other countries because Iran has its own Crud Oil rigs and raw material for the production of Diesel Fuel without having to import crude oil.
