Diesel generators are a popular choice for backup power during outages or for off-grid living. However, in some situations, diesel fuel may not be readily available or may be too expensive. In these cases, kerosene may be a viable alternative fuel source for diesel generators.
While diesel and kerosene are both petroleum-based fuels, they have different properties that affect their performance in engines. It is important to understand the differences between diesel and kerosene, as well as the combustion and burning properties of each fuel, to determine whether a diesel generator can run on kerosene and what impact it may have on the generator’s efficiency and lifespan.
Key Takeaways
- Diesel generators can potentially run on kerosene, but it is important to understand the differences between the fuels and their combustion properties.
- Kerosene does not contain the lubricating properties of diesel, which can affect engine wear and lifespan.
- Safety considerations must be taken into account when using kerosene as a fuel source for diesel generators.
Understanding Diesel and Kerosene
Diesel and kerosene are two types of fuels that are commonly used in generators and other equipment. Both fuels are derived from petroleum and have similar chemical compositions. However, there are some differences between the two that make them better suited for different applications.
One of the main differences between diesel and kerosene is their chemical composition. Diesel fuel contains more hydrocarbons than kerosene, which makes it a more energy-dense fuel. Kerosene, on the other hand, has a lower energy density but burns more cleanly than diesel.
Another important difference between diesel and kerosene is their properties. Diesel fuel has a higher viscosity than kerosene, which makes it thicker and more difficult to flow through pipes and fuel lines. Kerosene, on the other hand, has a lower viscosity and is easier to handle and transport.
When it comes to using diesel and kerosene in generators, there are some important considerations to keep in mind. While diesel generators are designed to run on diesel fuel, it is possible to use kerosene as a substitute. However, it is important to note that kerosene does not contain the same lubricating properties as diesel fuel, which can lead to increased wear and tear on the generator’s engine.
Diesel Generators Explained
Diesel generators are a popular choice for backup power supply because of their reliability and efficiency. They are commonly used in homes, businesses, and industries to provide power during power outages or in remote locations where there is no access to the power grid.
A diesel generator works by converting diesel fuel into electrical power. The generator consists of an engine, an alternator, and a fuel system. The engine burns diesel fuel to produce mechanical power, which is then converted into electrical power by the alternator. The fuel system supplies diesel fuel to the engine and regulates its flow.
Diesel generators are known for their durability and low maintenance requirements. They are designed to operate for extended periods without interruption and can withstand harsh environments. However, regular maintenance is still necessary to ensure optimal performance and prevent breakdowns. Maintenance tasks include oil changes, filter replacements, and inspections of the fuel system and electrical components.
One of the advantages of diesel generators is their fuel efficiency. They are more fuel-efficient than gasoline generators, which means they can produce more power with less fuel. This makes them a cost-effective option for backup power supply.
In terms of power output, diesel generators can range from small portable units to large industrial-scale generators. The power output of a diesel generator is measured in kilowatts (kW) and can range from a few kW to several thousand kW.
Kerosene Generators and Their Functionality
Kerosene generators are designed to provide power during power outages or in remote areas where a reliable source of electricity is not available. These generators are powered by kerosene, which is a type of fuel that is commonly used for heating and lighting purposes.
Kerosene generators operate in a similar way to diesel generators. They have an internal combustion engine that converts the energy from burning kerosene into mechanical energy, which is then used to generate electricity. The generator consists of a fuel tank, an engine, and a generator head, which contains the electrical components that produce the electricity.
Kerosene generators are typically smaller and less powerful than diesel generators. They are suitable for powering small appliances, such as lights, fans, and small electronic devices. They are not suitable for powering large appliances or heavy machinery.
One of the advantages of kerosene generators is that they are more efficient than gasoline generators. Kerosene has a higher energy density than gasoline, which means that it provides more energy per unit of volume. This makes kerosene generators more fuel-efficient and cost-effective to operate.
In addition, kerosene is a more stable fuel than gasoline, which means that it can be stored for longer periods without deteriorating. This makes kerosene generators more reliable and easier to maintain than gasoline generators.
Fuel Types for Generators
Generators require fuel to operate, and there are several options available for powering them. The most common fuel types for generators are gasoline, propane, natural gas, diesel, and fuel oil. Each fuel type has its own advantages and disadvantages, and the best option for you will depend on your specific needs and circumstances.
Gasoline
Gasoline is a popular fuel choice for portable residential generators because it is readily available and easy to use. However, gasoline has a shorter shelf life and flash-point temperature than some of its counterparts, which means it can ignite at lower temperatures when compared to diesel fuel, for example. Additionally, gasoline tends to be more expensive than other fuel types, so it may not be the most cost-effective option in the long run.
Propane
Propane is a clean-burning fuel that produces fewer emissions than gasoline or diesel. It is also readily available and easy to use, making it a popular choice for both residential and commercial generators. Propane is stored in tanks, which can be refilled when needed, making it a convenient option for those who want a fuel source that requires minimal maintenance.
Natural Gas
Natural gas is another clean-burning fuel that is commonly used to power generators. It is often used in commercial settings, such as hospitals and data centers, because it is reliable and produces fewer emissions than other fuel types. However, natural gas generators can be more expensive to install and maintain than other options, so they may not be the best choice for residential use.
Diesel
Diesel is a popular fuel choice for larger generators because it is efficient and produces more power than gasoline. It is also readily available and easy to use, making it a popular choice for both residential and commercial generators. Diesel generators can be more expensive to purchase and maintain than other options, but they are often more reliable and efficient in the long run.
Fuel Oil
Fuel oil is a type of petroleum-based fuel that is commonly used to power generators. It is often used in commercial settings, such as hospitals and data centers, because it is reliable and produces more power than other fuel types. However, fuel oil generators can be more expensive to install and maintain than other options, so they may not be the best choice for residential use.

Combustion and Burning Properties
Kerosene and diesel have very similar combustion qualities, and as a result, diesel can run smoothly in a kerosene generator. In fact, kerosene is an authorized fuel for many modern diesel engines. Pure kerosene is produced by a distillation process. The combustion process of kerosene is similar to that of diesel, and it will burn without damaging most diesel engines.
When it comes to burning properties, diesel has a higher cetane number than kerosene, which means it ignites more easily. Kerosene, on the other hand, has a lower flash point and burns at a lower temperature than diesel. Therefore, when using kerosene in a diesel engine, you may need to adjust the throttle tuner to rev it a bit slower as diesel has more lubricating properties.
In terms of emissions, kerosene burns cleaner than diesel, producing less smoke and particulate matter. However, diesel has a higher energy content than kerosene, which means it can produce more power and run more efficiently.
Efficiency of Diesel vs Kerosene
When it comes to fuel efficiency, diesel is generally considered to be more efficient than kerosene. This is because diesel has a higher energy density than kerosene, meaning that it contains more energy per unit of volume. Diesel typically has a heat value of around 130,000 BTUs per gallon, while kerosene has a heat value of around 135,000 BTUs per gallon.
However, it is important to note that the efficiency of a diesel generator running on kerosene may vary depending on the specific generator and the conditions under which it is operating. In some cases, a generator may actually be more efficient when running on kerosene than when running on diesel. This is because kerosene has a lower viscosity than diesel, which can reduce friction and improve efficiency.
In addition to energy density and viscosity, other factors can also affect the efficiency of a diesel generator running on kerosene. For example, the quality of the fuel, the age and condition of the generator, and the load being placed on the generator can all impact its efficiency.
Lubrication and Wear in Engines
In any engine, lubrication is critical to reduce wear and prolong the life of the engine. In diesel engines, the fuel itself serves as a lubricant, providing the necessary lubricating properties to the engine. Kerosene, on the other hand, does not have the same lubricating properties as diesel fuel.
When kerosene is used in a diesel engine, the lack of lubrication can cause increased wear on the engine’s components, particularly the valves. This can result in decreased engine performance and a shorter lifespan for the engine.
It is important to note that while some diesel generators may be able to run on kerosene, it is not recommended to do so for extended periods of time. The lack of lubricating properties in kerosene can cause significant wear and damage to the engine over time.
If kerosene must be used in a diesel engine, it is recommended to use a high-quality lubricant additive to help mitigate the effects of the lack of lubrication. Additionally, regular maintenance and monitoring of the engine’s performance is crucial to catch any issues early on and prevent further damage.
Impact of Kerosene on Diesel Generators
Diesel generators are designed to run on diesel fuel, but kerosene can also be used as an alternative fuel source. However, there are some important considerations to keep in mind when using kerosene in a diesel generator.
One of the main differences between diesel and kerosene is the lubricating properties. Diesel contains lubricating additives that help protect the engine from wear and tear, whereas kerosene does not. This means that running a diesel generator on kerosene can cause more wear and tear on the engine, which can lead to increased maintenance costs over time.
Another important consideration is the quality of the kerosene being used. Low-quality kerosene can contain impurities and contaminants that can clog the fuel filter and cause damage to the engine. It is important to use high-quality kerosene and change the fuel filter regularly to prevent any issues.
In addition, it is recommended to use additives and cleaners specifically designed for diesel engines when using kerosene in a diesel generator. These additives can help improve the lubricating properties of the fuel and prevent any buildup of deposits or contaminants in the engine.
Kerosene as a Fuel Alternative in Winter
During the winter season, diesel fuel can become thicker and even gel up due to the cold weather. This can cause problems for diesel generators, as the fuel may not flow properly through the system. However, kerosene can be used as a fuel alternative in the winter to prevent these issues.
Kerosene has a lower cold filter plugging point (CFPP) than diesel fuel, which means it can flow more easily in cold temperatures. This makes it a popular choice for heating oil and kerosene heaters during the winter season. In fact, many heating oil companies blend kerosene with diesel fuel to create a winterized fuel that can withstand cold temperatures.
When using kerosene as a fuel alternative for diesel generators, it’s important to note that it doesn’t contain the same lubricating properties as diesel fuel. This means that over time, it can cause wear and tear on the engine if used exclusively. However, using kerosene as a temporary solution during the winter months can help prevent fuel-related issues.
It’s also worth noting that kerosene is typically less expensive than diesel fuel, which can be a cost-saving measure for those who rely on diesel generators during the winter season. However, it’s important to ensure that the generator is compatible with kerosene before making the switch.
Environmental Impact and Emissions
It is essential to consider the environmental impact of using kerosene as a fuel for a diesel generator. When diesel fuel is burned in engines, the emissions that result contribute to air pollution that has serious human health and environmental effects. Similarly, kerosene combustion also produces toxic fumes and pollutants that contribute to environmental degradation.
The emissions from diesel exhaust include soot or particulate matter (PM), oxides of nitrogen (NOx), hydrocarbons (HC), and other harmful pollutants. These emissions can cause respiratory problems, cardiovascular diseases, and other health issues, especially for people living in urban areas with high levels of air pollution.
On the other hand, kerosene combustion also produces pollutants such as carbon monoxide (CO), nitrogen oxides (NOx), and sulfur dioxide (SO2), which can cause respiratory problems, acid rain, and other environmental issues.
To reduce the environmental impact of using kerosene in a diesel generator, it is essential to ensure that the generator is well-maintained and operates efficiently. Regular maintenance and cleaning of the generator can help reduce emissions and improve its performance.
Additionally, using biodiesel-kerosene or biodiesel-kerosene-diesel blends can also help reduce emissions and improve the generator’s performance. These blends are made from renewable resources and have lower emissions compared to pure kerosene or diesel fuel.
Cost Effectiveness of Kerosene vs Diesel
When it comes to running a diesel generator, fuel costs can be a significant factor to consider. Kerosene is often cheaper than diesel, making it an attractive alternative. Here are some factors to consider when comparing the cost-effectiveness of kerosene vs diesel:
- Price Point: Kerosene is generally cheaper than diesel fuel, which can make a significant difference in the long run.
- Availability: Kerosene is widely available in many areas, but it may not be as readily available as diesel in some locations. It is important to consider the availability of both fuels when deciding which one to use.
- Efficiency: Diesel is generally more efficient than kerosene, which means that you may need to use more kerosene to generate the same amount of power as diesel. This can offset some of the cost savings of using kerosene instead of diesel.
- Maintenance Costs: Using kerosene instead of diesel may increase maintenance costs over time. Kerosene does not contain the same lubricating properties as diesel, which can lead to increased wear and tear on the generator’s engine.
Safety Considerations When Using Kerosene
When using kerosene with a diesel generator, it is important to keep safety considerations in mind. Here are some things to keep in mind:
- Kerosene is a highly flammable liquid. It is important to store it in a safe place away from heat sources, sparks, and open flames.
- Kerosene has a flashpoint of around 100°F, which means that it can ignite easily at relatively low temperatures. This is why it is important to handle it with care and to use it only in well-ventilated areas.
- When using kerosene with a diesel generator, it is important to follow the manufacturer’s instructions carefully. This includes using the correct fuel mixture and ensuring that the generator is properly ventilated.
- It is also important to use the correct type of container to store kerosene. This should be a container that is specifically designed for storing flammable liquids and is made from a material that is resistant to corrosion and leakage.
- When handling kerosene, it is important to wear protective clothing, such as gloves and goggles, to prevent skin and eye irritation.
- If you spill kerosene, it is important to clean it up immediately. This can be done using absorbent materials such as sand or kitty litter. Do not use water to clean up kerosene spills, as this can spread the spill and increase the risk of fire.
- It is also important to dispose of kerosene safely. This should be done in accordance with local regulations and guidelines.
By following these safety considerations, you can use kerosene safely with a diesel generator and avoid any potential hazards.
