Diesel fuel was discovered in the 1890s by Rudolf Diesel, a German inventor and engineer. Diesel fuel is derived from crude oil, which is extracted from the ground and sent to refineries to be turned into gasoline, diesel, kerosene, and other extracts. The first diesel engine prototype was invented in 1892 and was designed to work with a diverse range of fuels. The first diesel engines were large and operated at low speeds due to the limitations of their compressed air-assisted fuel injection systems.

Rudolf Diesel invented the diesel engine in the 1890s
After graduating from Munich Polytechnic, Diesel began working as a refrigerator engineer for the Linde Ice Machine Company in Paris. In 1890, he moved to Berlin to manage the company's technical office. However, he remained passionate about engine design and devoted his free time to developing a more efficient thermal engine.
Diesel completed his design by 1892 and received a German patent for it in the same year. The following year, he published a description of his engine under the title "Theorie und Konstruktion eines rationellen Wäremotors" (Theory and Construction of a Rational Heat Motor). With support from the Maschinenfabrik Augsburg and the Krupp firms, he produced a series of successful models, leading up to his demonstration in 1897 of a 25-horsepower, four-stroke, single vertical cylinder compression engine.
The diesel engine was a significant innovation during the Industrial Revolution, providing a more efficient and cost-effective power source for various industries. Unlike traditional engines, it did not require an external ignition source and could burn a variety of fuels, including vegetable seed oil and peanut oil. This versatility and efficiency revolutionized the locomotive industry, as diesel fuel did not need to be externally ignited like coal, making it a more convenient and economical option.

Diesel engines are more fuel-efficient than other internal combustion engines
Rudolf Diesel invented the diesel engine in the late 1800s, specifically designed to use the byproduct of the oil refinement process that was previously discarded. The first diesel engine prototype was designed for liquid fuels, and diesel fuel was standardised soon after.
Diesel engines are also more durable, with heavier parts such as the crankshaft and pistons, which can withstand higher pressure from compressed air. They are built to be strong and long-lasting, making them ideal for industries such as construction, transportation, and agriculture, where durability, power, and fuel efficiency are crucial.
Additionally, diesel fuel has a higher energy density, providing more power and better mileage. It is thicker than gasoline and has more energy, resulting in higher torque generation. This makes diesel engines well-suited for towing and hauling heavy loads.
However, it is important to note that diesel engines are generally more expensive to purchase initially and have higher nitrogen oxide and particulate matter emissions, contributing to environmental concerns. Gas engines, on the other hand, offer quicker acceleration, smoother operation, and lower emissions, making them better for daily driving and lighter tasks.

Diesel fuel is derived from crude oil
Diesel fuel is a distillate fuel oil designed for use in motor vehicles that use the compression-ignition engine invented by Rudolf Diesel in 1892. Diesel fuel is derived from crude oil, which is extracted from the ground through wells and offshore rigs. Crude oil is a naturally occurring liquid that can be refined into various fuels and other petroleum-based products.
The process of deriving diesel fuel from crude oil begins with heating the viscous crude oil to over 400 degrees Celsius, turning it into vapour. This vapour then enters a fractional distillation tower, where it cools down and turns back into a liquid. The liquid that emerges from this process is asphalt or bitumen, which exits at the bottom of the tower. As the vapour rises, it continues to cool, and shorter hydrocarbon chains begin to liquefy. When the vapour cools down below 370 degrees Celsius, fuel oil is formed.
The specific type of diesel fuel known as petroleum diesel or petrodiesel is produced by the fractional distillation of crude oil between 200 and 350 degrees Celsius at atmospheric pressure. This results in a mixture of carbon chains containing between 9 and 25 carbon atoms per molecule. This fraction undergoes further processing, including hydrodesulfurization, to remove impurities and adjust its properties for specific applications.
In addition to petroleum-derived diesel, alternative types of diesel fuel that are not derived from crude oil are also available. These include biodiesel, biomass-to-liquid (BTL), and gas-to-liquid (GTL) diesel. Biodiesel, for example, is produced from vegetable oil or animal fats, while synthetic diesel can be manufactured from various carbonaceous precursors, with natural gas being the most important. The development and adoption of these alternative diesel fuels reflect a growing trend towards diversifying fuel sources and reducing reliance solely on petroleum-derived products.

Before diesel fuel was standardised, diesel engines ran on cheap fuel oils
Rudolf Diesel invented the diesel engine in the 1890s, aiming to develop a highly efficient engine by converting heat into power. The first diesel engine prototype and the first functional diesel engine were designed for liquid fuels. During his first diesel engine tests, Diesel used illuminating gas as fuel and managed to build functional designs, both with and without pilot injection.
Before diesel fuel was standardised, diesel engines typically ran on cheap fuel oils. In the United States, these were distilled from petroleum, whereas in Europe, coal-tar creosote oil was used. These fuel oils are still used in watercraft diesel engines. Diesel engines can also be fuelled with mixtures of fuels, such as petrol, kerosene, rapeseed oil, or lubricating oil. These mixtures were cheaper because they were not taxed.
The first oil refinery was built in 1851 in Scotland and used primarily to extract paraffin for oil lamps. Eventually, kerosene was a common by-product that replaced paraffin. Diesel was also a common by-product but was frequently discarded because there was no use for it. It wasn't until Rudolf Diesel designed the first engine capable of using this by-product that the fuel was seen as a resource.
The first diesel engine production model was made in 1897. The diesel engine was a significant improvement over the steam engines of the time, which required copious amounts of coal to run. The diesel engine revolutionised the locomotive industry because it was the first fuel that didn't need to be externally ignited.

Diesel fuel is also known as distillate, gas oil, or simply diesel
Diesel fuel, also known as diesel oil, heavy oil, or simply diesel, is any liquid fuel specifically designed for diesel engines. Diesel engines are a type of internal combustion engine in which fuel ignition occurs without a spark as a result of compression of the inlet air and then injection of fuel. Thus, diesel fuel needs good compression ignition characteristics.
The most common type of diesel fuel is a specific fractional distillate of petroleum fuel oil. Diesel fuel is derived from the distillation of crude oil, which is extracted from the ground through wells and offshore rigs. The crude oil is sent to refineries, where it is heated and turned into gasoline, diesel, kerosene, and other extracts. The vapors are captured in another tank to condense into a new liquid, and the process continues as various distillates are captured and cooled.
In the United States, diesel fuel is typically refined from crude oil at petroleum refineries, producing an average of 11 to 12 gallons of diesel fuel from each 42-gallon barrel of crude oil. The fractional distillation of crude oil occurs between 200 and 350 °C at atmospheric pressure, resulting in a mixture of carbon chains containing 9 to 25 carbon atoms per molecule. This process can also be achieved through biomass, animal fat, biogas, natural gas, and coal liquefaction.
In Australia, diesel fuel is known as distillate, while in Indonesia, Israel, and most of the Middle East, it is known as Solar, a trademarked name from the national petroleum company Pertamina. The term gas oil (French: gazole) is also used to refer to diesel fuel. Diesel fuel was first discovered through experiments conducted by German scientist and inventor Rudolf Diesel for his compression-ignition engine, which he invented and patented around 1892.
