Diesel fuel, also known as diesel oil, is a combustible liquid used as a fuel for diesel engines. It is obtained from fractions of crude oil that are less volatile than gasoline. The most common type of diesel fuel is a specific fractional distillate of petroleum fuel oil, which is refined from crude oil and biomass materials. Diesel fuel is used in trucks, trains, boats, construction, farming, and military vehicles and equipment. It is also used in diesel engine generators to generate electricity, particularly in remote villages in Alaska. In the United States, there are different grades of diesel fuel specified by the American Society of Testing and Materials, which are classified according to viscosity, sulfur content, and application.

What You'll Learn
Diesel fuel is used in trucks, trains, boats and cars
Diesel fuel, also called diesel oil, is a combustible liquid used in diesel engines. It is a mixture of hydrocarbons obtained by distillation of crude oil. The most common type of diesel fuel is a specific fractional distillate of petroleum fuel oil, with a boiling point between 150 to 380°C. Diesel fuel is used in a range of vehicles, including trucks, trains, boats and cars.
Trucks are one of the most common uses of diesel engines. Freight and delivery trucks often use diesel fuel, as well as those used by the military. Diesel fuel is less flammable and less explosive than other fuels, making it a safer option for military use. It is also used in construction, farming and mining equipment. Diesel engines are favoured in these industries due to their high torque output, durability, fuel economy and ability to provide power across a wide range of conditions.
Diesel fuel is also used in trains, with most of the products we use being transported by diesel trains. Diesel engines are used in rail transport around the world.
In addition, diesel fuel is used in boats and other watercraft. Before diesel fuel was standardised, diesel engines typically ran on cheap fuel oils, and these are still used in watercraft diesel engines. Diesel propulsion gained prevalence in the late 1970s due to increasing fuel costs, and these heavy fuel oils are still used today.
Finally, diesel fuel is used in cars. While less common than diesel trucks, trains and boats, some cars do have diesel engines.

It's used in generators for electricity
Diesel fuel is used in a variety of applications, with a range of vehicle engines and boilers designed to run on diesel. One important use of diesel fuel is in diesel generators, which are used to generate electricity.
A diesel generator (DG) combines a diesel engine with an electric generator (often an alternator) to generate electrical energy. The diesel engine is an internal combustion engine that uses the heat of compression to ignite and burn the fuel injected into the injection chamber. This is in contrast to a gasoline engine, which uses a spark to ignite the fuel. Diesel generators are used in a variety of settings, from rural areas to large buildings and industrial facilities, and can serve as a main power source or a backup system.
In rural areas, diesel generators are often used as the main power source for off-grid homes and communities, providing electricity where there is no connection to a power grid. They are also used in remote locations such as remote villages in Alaska, where they are relied upon to supply much-needed electrical energy. Diesel generators are well-suited for this purpose as they can be turned on and off quickly without any lag time.
In addition to providing primary power, diesel generators are commonly used as a backup or emergency power supply in the event of interruptions to the main power grid. Many industrial facilities, large buildings, institutional facilities, hospitals, and electric utilities have diesel generators for this purpose. Diesel generators are also used to balance the fluctuating output from renewable energy sources, such as wind farms. In these cases, the diesel generators feed power into the grid during peak periods or when there is a shortage of large power generators.
The size of a diesel generator is an important consideration, as it affects the power output and efficiency of the system. Diesel generators can range in size from small, portable units to large, fixed installations. The sizing of a diesel generator depends on various factors, including the electrical load it is intended to supply and the characteristics of modern electronics, such as non-linear loads. Manufacturers often provide software to perform the complicated sizing calculations based on site conditions and connected electrical load characteristics.

Used in farming, construction and mining equipment
Diesel fuel is widely used in farming, construction, and mining equipment. In the US, diesel fuel powers about 75% of farm equipment and helps pump 20% of the water used for irrigation. It is used in tractors, harvesters, and other heavy equipment for plowing, planting, harvesting, and transportation tasks. Diesel engines are preferred in farming due to their higher energy output, low-RPM performance, and higher compression ratio compared to gasoline engines.
In the construction sector, diesel fuel is favoured for its high energy density and efficiency. It powers more than three-fourths of heavy construction equipment, including earthmovers, bulldozers, bucket loaders, backhoes, cranes, pavers, excavators, and motor graders. Diesel engines are used for demanding tasks such as lifting steel beams, digging foundations and trenches, drilling wells, paving roads, and moving soil and rocks.
The mining industry also relies heavily on diesel-powered equipment, with an estimated $7 billion worth of diesel-powered machinery in use. However, diesel emissions in mining are a concern, and regulations have been put in place to control worker exposure to diesel particulate matter.
Overall, diesel fuel plays a crucial role in powering the heavy machinery and equipment used in farming, construction, and mining. While there is a growing trend towards cleaner energy alternatives, diesel remains a key source of energy in these sectors due to its performance, efficiency, and durability.

Used in military tanks and trucks
Diesel fuel is one of the primary fuels used to power military vehicles, including tanks and trucks, during deployment. It is favoured due to its efficiency, durability, safety, and performance. Diesel engines are also less likely to stall than gasoline-fuelled engines.
During World War II, the US, Britain, and Germany did not widely use diesel engines in their tanks, trucks, and other heavy vehicles. Instead, they opted for gasoline engines due to various reasons. Firstly, gasoline engines used less metal to produce and required a more abundant fuel source. Secondly, mass-producing vehicles with the same fuel type simplified logistics and allowed for the production of greater quantities to overwhelm the enemy. Lastly, tubocharging and aftercooling technologies, which could have improved diesel engine performance, were not commonly practised until long after World War II.
However, the advantages of diesel engines over gasoline engines were already understood at the time. Diesel engines offer greater torque, durability, less maintenance, and most importantly, they use a less combustible fuel. This means that a direct hit on a diesel fuel tank is less likely to result in a catastrophic explosion compared to a gasoline fuel tank.
Since World War II, the use of diesel engines in military tanks and trucks has become more common. The American M1 Abrams Main Battle Tank, for example, uses a multifuel gas turbine engine that can run on diesel fuel. Similarly, the Russian T-72 tank is a diesel-powered vehicle. The US military has also developed diesel-powered trucks, such as the M1070, capable of transporting tanks through various terrains within tight time limits.

Used in marine shipping
Marine diesel oil (MDO) is a type of distillate diesel oil used in marine shipping. It is widely used by medium-speed and medium/high-speed marine diesel engines. It is also used in larger low-speed and medium-speed propulsion engines, which usually burn residual fuel. MDO is crafted from refinery leftovers by blending suitable residual products with low-sulphur distillates. This process creates a high-quality fuel that adheres to the International Maritime Organization's (IMO) sulphur cap of 0.5%.
The shipping industry favours MDO due to its lower price compared to more refined fuels. However, MDO has been criticised for its high sulphur content, leading several countries and organisations to establish regulations and laws regarding its use. For example, the IMO has implemented regulations to limit sulphur emissions from shipping, such as the 2012 limit of 3.5% and the more stringent 0.5% limit by 2020. To comply with these regulations, ships can install marine scrubbers to clean exhaust gases and limit sulphur oxide emissions.
Ultra-low sulphur diesel fuel (ULSD) is another type of fuel used in the maritime industry. It is designed to have a very low sulphur content, typically about 0.0015%. ULSD is used in shipping zones with strict sulphur regulations, such as the Baltic Sea, ports in Iceland, Norway, Turkey, inland ports in China, and some ports in South Korea.
Biodiesel is also an alternative fuel gaining traction in the maritime industry. Derived from natural oils and fats, biodiesel can reduce dependence on traditional fossil fuels. It is compatible with most diesel engines without requiring significant modifications. However, biodiesel's lower energy density leads to more frequent refuelling stops, and it is generally more expensive than conventional marine fuels.
When choosing a marine fuel, factors such as vessel size, cost, availability, and operational requirements must be considered. Diesel offers an unmatched range and reliability, but its higher cost may not suit all operators. Heavy fuel oil (HFO) is a cheaper alternative, but it has high sulphur oxide emissions, which can be harmful to people near ports and has a negative environmental impact.
