Gasoil (Diesel or D2) is a group of petroleum distillation products having boiling points between Lubricating Oil and Kerosene. The term originally referred to the product of oil gas works that was added to the product of coal gas works to produce improved illuminating gas.
It is the second distillate from the processing of crude oil. It can be used without reformers and additives. D2 has helped in a major reduction of wasted energy, pollution and waste. It can be used without reformers and additives. Thus, the first engines used D2 as fuel, before gasoline cars as we know them today were invented. This is because the engine, invented by a German named Diesel, does not require spark plugs. The diesel engine will ignite and burn when the pressure increases, so that the heated “spark plug” causes it to explode.
Diesel engines are used worldwide due to higher thermodynamic efficiency and thus fuel efficiently.
Tractors and heavy equipment
In the United States, petroleum-derived diesel is composed of about 75% saturated hydrocarbons (primarily paraffins including n, iso, and cycloparaffins), and 25% aromatic hydrocarbons (including naphthalenes and alkylbenzenes). The average chemical formula for common diesel fuel is C12H23, ranging approximately from C10H20 to C15H28.
