It is a high-volume product of oil refineries, derived from various sources including biomass and biogas
Diesel fuel is a high-volume product of oil refineries, derived from various sources, including biomass and biogas.
Diesel fuel, also known as diesel oil or simply diesel, is designed for use in diesel engines, which are a type of internal combustion engine. Diesel engines do not require spark ignition, as the inlet air is compressed and then the fuel is injected. Diesel fuel is most commonly derived from the fractional distillation of petroleum fuel oil, but alternative sources are becoming more common. These alternatives are not derived from petroleum but include biodiesel, biomass-to-liquid (BTL), or gas-to-liquid (GTL) diesel.
Biomass is a renewable energy source that can be converted directly into liquid biofuels to meet transportation fuel needs. Ethanol and biodiesel are the two most common types of biofuels currently in use. Ethanol is a renewable fuel made from various plant materials, or biomass, and is often used as a blending agent with gasoline to increase octane and reduce carbon monoxide and other harmful emissions. Biodiesel is also derived from biomass and is a liquid fuel produced from renewable sources such as vegetable oils, animal fats, or recycled greases. It is a cleaner-burning replacement for petroleum-based diesel fuel and can be blended with petroleum diesel to improve combustion properties.
The process of converting biomass into ethanol is called fermentation, where microorganisms break down plant sugars to produce ethanol. Biodiesel is produced through a transesterification process, where alcohol is combined with vegetable oil, animal fat, or recycled cooking grease to create a non-toxic, biodegradable fuel. This process can also use methanol, which can be derived from renewable sources such as carbon dioxide or biomass, making the production free of fossil fuels.
The use of biodiesel and biomass-based diesel fuels is increasing, particularly in the United States, where most diesel fuel is refined from crude oil. Diesel fuel is widely used in trucks, trains, boats, and construction and farming equipment, as well as for backup and emergency power generation in many industrial and institutional facilities.

Diesel fuel is also used in non-diesel engines such as the Stirling engine
Diesel fuel, also known as diesel oil, heavy oil, or simply diesel, is a liquid fuel designed for use in diesel engines. Diesel engines are a type of internal combustion engine where fuel ignition occurs without a spark due to the compression of inlet air and subsequent fuel injection. While diesel fuel is primarily intended for diesel engines, it can also be used in certain non-diesel engines, such as the Stirling engine.
The Stirling engine, invented by Robert Stirling and his brother James, is an external combustion engine. It operates through the cyclic expansion and contraction of air or other gases (known as the "working fluid") by exposing them to different temperatures. This results in the conversion of heat energy into mechanical work. The Stirling engine is a closed-cycle system, meaning the working fluid is permanently contained within it.
One of the key advantages of the Stirling engine is its ability to run on a diverse range of fuels. Since the combustion process is isolated from the working parts of the engine, it can utilise fuels that would typically damage other engine types. For example, landfill gas, which contains siloxane, can be used as a heat source in a Stirling engine without the risk of depositing abrasive silicon dioxide in the engine's internals. This versatility in fuel choice makes the Stirling engine a unique and adaptable power source.
Diesel fuel can be used in Stirling engines, providing an alternative to the engine's typical fuel sources. While diesel fuel is commonly associated with diesel engines, its use in Stirling engines highlights its versatility and applicability in non-diesel contexts. Diesel fuel's combustion properties and energy density make it a viable option for Stirling engines, particularly in situations where the engine's typical fuel sources may be limited or impractical.
In addition to the Stirling engine, diesel fuel also finds applications in other non-diesel engines, such as the Akroyd engine and boilers for steam engines. This adaptability showcases the versatility of diesel fuel and its ability to power a range of engines and machinery beyond its original intended use in diesel engines alone.
