Diesel (Gasoil) D2 is a group of petroleum distillation products with boiling points between Lubricating Oil and Kerosene. It is the second distillate from crude oil processing and can be used without reformers and additives. The principal difference between GASOIL and D2 is the sulfur content.
Usage
Diesel D2 is a liquid fuel used in diesel engines, where fuel ignition takes place due to compression rather than a spark. Truckers prefer Diesel #2 for long-distance heavy loads due to its lower volatility and better fuel economy.
Properties and Efficiency
It is created through fractional distillation and used in automotive applications and heating. Diesel engines offer high thermodynamic efficiency. The fuel's composition changes seasonally; winter diesel includes additives to prevent freezing and enhance performance in cold temperatures.
Diesel (Gasoil) D2 Variants
Gasoil, also known as fuel oil, heavy oil, marine fuel, bunker, or furnace oil, consists of distillates and residues. Fuel oil is burned in furnaces, boilers, and engines for heat and power generation.
Fuel Composition
Fuel oil consists of long-chain hydrocarbons like alkanes, cycloalkanes, and aromatics. Heavier petroleum products such as diesel fuel and lubricating oil distill more slowly than lighter products like gasoline and jet fuel.
Environmental Standards
The GOST 305–82 variant of Diesel D2 has a lower sulfur content of 0.2% maximum, aligning with ISO industry standards for Ultra Low Sulfur Diesel (ULSD). This reduces pollution and meets North American and European regulations.
