D2 diesel fuel

D2 DIESEL

D2 diesel, also called Gasoil, is a fuel oil that is the second distillate derived from crude oil. D2 diesel products contain different levels of sulfur and require no reformers or additives to produce. Standard diesel fuel (sometimes called diesel oil) comes in two grades: Diesel #1 (or 1-D) and Diesel #2 (or 2-D). 

 

D2 diesel fuel is the broad category for the second distillate of crude oil. Ultra-low sulfur grades of D2, such as GOST 305-82, reduce sulfur content to a maximum of 0.02 percent and reduce sulfur pollution emissions.


Diesel fuel is often used in diesel engines. Diesel engines, also called compression ignition engines, rely on the temperature increase of compression, rather than on spark plugs, to achieve reliable ignition timing and combustion efficiency.


As a result of their inherently higher compression ratio for a given power output, diesel engines are more fuel-efficient than spark ignition engines. However, compared with spark ignition automotive engines, diesel engines weigh more, generate more vibration and produce greater particulate or soot emissions. Diesel engines can also produce a particularly carcinogenic type of hydrocarbon pollutant known as polycyclic aromatic hydrocarbons (PAHs), which are generated during the diesel combustion process.

The cetane index is a measure of the auto ignition quality of a diesel fuel, with higher numbers meaning that the engine is easier to start in cold weather.


D2 is also a distillate home heating oil. Trucks and some cars use similar diesel fuel with a cetane number limit describing the ignition quality of the fuel. Both are typically obtained from the light gas oil cut. Gas oil refers to the original use of this fraction in the late 19th and early 20th centuries - the gas oil cut was used as an enriching agent for carbureted water gas manufacture
