Diesel D2 Russian Gasoil L-0.2-62 Gost 305-82 Standard diesel fuel (sometimes called diesel oil) comes in two grades: Diesel-1 (D1) and Diesel-2 (D2). Diesel or Diesel fuel in general is any fuel used in diesel engines. That’s why it’s also commonly called as AGO or Automotive Gas Oil. Diesel fuel is a type of fuel derived from the distillation of oil that is heavier than gasoline but lighter than engine oil and heavy oil. D1 is similar to kerosene and is lighter than D2. While D2 is sold most of the time, D1 is sold during winter in very cold climates and not sold in hot weather countries. But D2 is easily available in most countries around the world. Despite rising awareness of environmental protection, D2 remains to be a key type of fuel for use in vehicles in many countries. In particular, demand for D2 has risen significantly in Asia over the past years as a consequence of increasing number of cars. In view of the country sustained economic growth, D2 will continue to be undersupply in the China/India and market.
EN590 describes the physical properties that all automotive diesel fuel must meet if it is to be sold in the European Union and Britain. Automotive diesel has various variants but the usual variants traded are EN590 and EN560 which are specified by ISO in Paris. EN590 for diesel (in Europe) has been around for almost 20 years. However, fuel like most products, is subject to a process of continuous development – and that development includes responding to legislation. The EN590 standard has been amended many times since 1993. 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.
Asphalt occasionally also known as bitumen is a sticky, black and highly viscous liquid or semi-solid form of petroleum. It may be found in natural deposits or may be a refined product; it is a substance classed as a pitch. Until the 20th century, the term asphaltum was also used. The word is derived from the Ancient Greek ásphaltos. The primary use (70%) of asphalt/bitumen is in road construction, where it is used as the glue or binder mixed with aggregate particles to create asphalt concrete. Its other main uses are for bituminous waterproofing products, including production of roofing felt and for sealing flat roofs. The terms asphalt and bitumen are often used interchangeably to mean both natural and manufactured forms of the substance. In asphalt (or asphalt cement) is the carefully refined residue from the distillation process of selected crude oils. Outside the United States, the product is often called bitumen. Geologists often prefer the term bitumen. Common usage often refers to various forms of asphalt/bitumen as "tar". Another archaic term for asphalt/bitumen is "pitch".
D6 is also be 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. 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).
