The world runs on diesel fuel, which powers everything from fleets of cargo trucks to construction equipment and passenger vehicles. The discovery of diesel fuel spurred the development of the first mass-produced combustion engines, which helped make the rapid expansion of the 20th century possible. While the production process is similar to kerosene and gasoline, diesel has some unique features that make it the fuel of choice for commercial vehicles and industrial applications.

Diesel Fuel: What It Is & How It's Made

The History of Diesel

In the 19th century, oil refineries in Pennsylvania producing kerosene for lamp oil inadvertently created several by-products, which didn’t seem to have any practical use. Eventually, Rudolf Diesel, the inventor of the modern compression ignition reciprocating engine, realized the by-products were a better fuel source than the coal dust he was using. The first diesel engine prototype was developed in 1895, a concept that’s still used today.

What Is Diesel Fuel?

Crude oil is composed of thousands of different compounds, each with several combinations of hydrogen and carbon atoms. Diesel has longer molecular chains than gasoline or ethane and a higher density of carbon atoms, which stores more energy. The density of diesel fuel makes it less flammable and more stable, with more power generated upon ignition.

How Diesel Fuel Is Made

Most hydrocarbon fuels, including diesel, are made by distilling crude oil. At the refinery, the lightest components are separated first, then funneled away to create gasoline, kerosene, propane, and jet fuel. The next-lightest material becomes diesel fuel, which is processed further to remove sulfur and other unwanted substances.
