Diesel fuel is a distillate fuel oil for use in compression ignition engines
Diesel fuel is a distillate fuel oil commonly used for motor vehicles with compression ignition engines. It is named after its inventor, Rudolf Diesel, who patented his original design in 1892. Diesel fuel is a mixture of hydrocarbons obtained through the distillation of crude oil. The refining process converts crude oil into transportation fuels such as gasoline, jet fuel, and diesel fuel, as well as other petroleum products.
The cetane number, which measures the delay of ignition of diesel fuel, is an important characteristic of diesel fuel quality. Diesel fuel with a higher cetane number ignites more easily when sprayed into hot compressed air. Additionally, diesel fuel has a higher density than gasoline, resulting in a higher volumetric energy density.
Diesel fuel is known for its use in high-speed diesel engines, particularly in motor vehicles such as cars and lorries. However, it is also used in various other applications, including generators for remote villages, industrial facilities, and backup power supply for hospitals and electric utilities.
Diesel fuel can be derived from crude oil or biomass materials, with the latter being increasingly adopted due to its environmental benefits. Biodiesel, for example, is a non-petroleum-based fuel that can be synthesised and used directly in many diesel engines.
In summary, diesel fuel is a distillate fuel oil specifically designed for compression ignition engines, offering advantages such as higher energy density and suitability for various vehicles and applications.

It is derived from crude oil through fractional distillation
Diesel fuel, also known as diesel oil, heavy oil, or simply diesel, is derived from crude oil through fractional distillation. This process involves heating the viscous crude oil to temperatures above 400°C, converting it into vapour. This vapour then rises up a fractional distillation tower, where it begins to cool. As the vapour cools, it reaches a certain temperature point at which the hydrocarbon chains within it return to a liquid state. Distillation plates within the tower capture these liquids at different levels, depending on their boiling temperature.
The longest hydrocarbon chains have a boiling point of over 400°C and emerge as asphalt or bitumen at the bottom of the tower. As the vapour rises, shorter hydrocarbon chains with lower boiling points begin to liquefy. Fuel oil, for example, emerges when the vapour cools down below 370°C. This process continues up the tower, with various distillates emerging at different temperatures. Diesel fuel is produced through this fractional distillation process, with boiling points ranging from 150 to 380°C.
Petroleum crude oils, which are used in the fractional distillation process, are composed of hydrocarbons from three major classes: paraffinic, naphthenic (or cycloparaffinic), and aromatic hydrocarbons. The average chemical formula for common diesel fuel is C12H23, with a range of approximately C10H20 to C15H28. The specific composition of diesel fuel can vary, depending on the source of crude oil and the refining processes employed.
While petroleum-derived diesel, or petrodiesel, is the most common type of diesel fuel, alternative sources that are not derived from petroleum are also available. These include biodiesel, biomass-to-liquid (BTL), and gas-to-liquid (GTL) diesel. Biodiesel, for instance, can be obtained from vegetable oil or animal fats, while synthetic diesel can be produced from various carbonaceous precursors, with natural gas being the most important. The development and adoption of these alternative diesel sources are becoming increasingly prevalent.
The process of refining crude oil into diesel fuel can vary in complexity and cost. Additional refining steps may be required to remove compounds such as sulfur, which contributes to higher fuel prices. The specifications for diesel fuel can differ based on fuel grades and vary across countries. However, certain properties are used to characterise diesel fuel, including cetane number, fuel volatility, density, viscosity, and sulfur content. These properties play a crucial role in determining the quality and performance of diesel fuel in engines.

Diesel fuel has a higher energy density than other liquid fuels
Diesel fuel is any liquid fuel specifically designed for use in a diesel engine, a type of internal combustion engine. Diesel engines are named after their inventor, Rudolf Diesel, who patented his original design in 1892. Diesel fuel is a mixture of hydrocarbons obtained by distillation of crude oil.
Diesel fuel has several advantages over other liquid fuels. Firstly, it has a higher energy density, providing more useful energy per unit of volume. This makes it a popular choice for transportation fuel, as it offers a wide range of performance, efficiency, and safety features.
The higher energy density of diesel fuel is due to its higher carbon content, which is approximately 86% of its mass. When burned, diesel fuel offers a net heating value of 43.1 MJ/kg, slightly higher than gasoline's 43.2 MJ/kg. The density of EN 590 diesel fuel is 0.820 to 0.845 kg/L, about 9.0-13.9% higher than gasoline's density.
In addition to its higher energy density, diesel fuel is also generally simpler to refine from petroleum than gasoline. However, additional refining is often required to remove sulfur, which contributes to higher costs. Regulations in several countries have been implemented to reduce the sulfur content in diesel fuel due to its harmful emissions.
Overall, the higher energy density of diesel fuel makes it a popular choice for transportation and other applications, despite the potential for higher costs due to the refining process.

It is safer than petrol but unsuitable for spark-ignition engines
Diesel fuel, also known as diesel oil, is a distillate fuel oil designed for use in diesel engines. These engines are a type of internal combustion engine in which fuel ignition occurs without a spark, as a result of the compression of inlet air and the subsequent injection of fuel. This means that diesel fuel is safer than petrol but unsuitable for spark-ignition engines.
Diesel fuel is a mixture of hydrocarbons obtained by distillation of crude oil. The distillation window is between 200°C and 350°C, with a boiling point range of approximately 163°C to 357°C. The principal measure of diesel fuel quality is its cetane number, which indicates how readily the fuel ignites when sprayed into hot compressed air. A higher cetane number denotes a fuel that ignites more easily.
The most common type of diesel fuel is a specific fractional distillate of petroleum fuel oil. However, alternative types that are not derived from petroleum, such as biodiesel, biomass-to-liquid (BTL), and gas-to-liquid (GTL) diesel, are becoming more prevalent. Diesel fuel is generally simpler to refine from petroleum than gasoline, although additional refining is required to remove sulfur, which can contribute to higher costs.
Diesel fuel offers a range of performance, efficiency, and safety features. It has a greater energy density than other liquid fuels, providing more useful energy per unit of volume. This makes it suitable for use in trucks, trains, boats, construction equipment, and military vehicles. Diesel fuel is also used in diesel-engine generators to provide electricity, particularly in remote areas.

Diesel fuel is subject to regulations to reduce its sulfur content
Diesel fuel is a mixture of hydrocarbons obtained by distillation of crude oil. It is used in diesel engines, a type of internal combustion engine in which fuel ignition occurs without a spark due to the compression of inlet air and the injection of fuel. Diesel fuel is generally simpler to refine from petroleum than gasoline, but additional refining is required to remove sulfur, which contributes to higher costs.
Sulfur is a natural derivative of the crude oil source and can remain present even after refining. When diesel fuel containing sulfur is burned, it creates sulfuric acid, which causes corrosive wear on the metal surfaces of an engine. This results in harmful corrosion and increased oil consumption, leading to reduced engine performance and efficiency. Furthermore, the combustion of sulfur-containing diesel fuel produces air pollution emissions that are harmful to human health.
Regulations have been implemented to reduce the sulfur content in diesel fuel and improve air quality. In 2006, the U.S. Environmental Protection Agency issued requirements to lower the sulfur content in diesel fuel sold in the United States. This transition to ultra-low-sulfur diesel (ULSD) has resulted in a 97% reduction in sulfur content compared to the 20th century. ULSD is now mandated for both on-highway and off-highway use, with a maximum sulfur content of 15 parts per million.
The reduction in sulfur content has had a positive impact on engine performance and the environment. Engines using ULSD no longer require high levels of detergents to protect against corrosion. Instead, modern engine oil formulations include a complex mix of detergent, antioxidant, and corrosion inhibitor additives to achieve optimum performance. The use of ULSD has also contributed to a significant decrease in SO2 and H2S emissions, improving air quality and reducing the negative impact of exhaust emissions on the environment and human health.
