Can a Car Run on Kerosene?
When it comes to fuel options for cars, gasoline has remained the primary choice for internal combustion engines. However, there has been curiosity and speculation surrounding the possibility of using kerosene as an alternative fuel. In this article, we will explore the characteristics of kerosene, its challenges as a fuel for car engines, and the potential modifications required to make it viable.
Fuel Characteristics
Kerosene is a petroleum distillate that is less refined than gasoline. It has a higher flashpoint, which means it requires more heat to vaporize and ignite compared to gasoline. Additionally, kerosene has a higher energy content per gallon, making it potentially more efficient in terms of energy output.
Fuel Vaporization
One of the primary challenges of using kerosene as a fuel in car engines is its vaporization. Kerosene needs to be vaporized before it can effectively burn in the engine. Due to its longer hydrocarbon chain compared to gasoline, more heat is required to achieve the necessary vaporization. In some cases, the intake manifold of the engine can be heated by the exhaust manifold to aid in fuel vaporization.
Preignition
Kerosene has a low octane rating, which makes it prone to preignition in gasoline engines. Preignition occurs when the fuel-air mixture ignites prematurely in the combustion chamber, leading to engine knocking and potential damage. To prevent preignition when running on kerosene, lower compression ratios or the use of anti-detonant additives may be necessary.
Engine Modifications
If one intends to run a car on kerosene, several modifications may be required. These modifications can include adjusting the compression ratio of the engine, using a different carburetor or fuel injection system, or installing a fuel heating system to aid in vaporization. It is important to note that these modifications might vary depending on the specific engine and its design.
It is worth mentioning that some small engines, such as those used in antique tractors, were designed to run on kerosene. These engines may require fewer modifications compared to modern car engines, as they were optimized for the specific characteristics of kerosene as a fuel.
In conclusion, while it is technically possible to run a car on kerosene, it is not a straightforward process. Kerosene’s distinct characteristics, such as its higher flashpoint and lower octane rating, present challenges that need to be addressed through engine modifications and careful optimization. Therefore, converting a gasoline engine to run on kerosene should be approached with caution, taking into consideration the specific requirements and potential risks involved.

Kerosene needs to be vaporized before it can effectively burn in a car engine. Due to its longer hydrocarbon chain compared to gasoline, more heat is required to achieve the necessary vaporization. Engine modifications may be necessary to aid in fuel vaporization.
What is preignition and how does it relate to kerosene?
Preignition occurs when the fuel-air mixture in the combustion chamber ignites prematurely, leading to engine knocking. Kerosene has a low octane rating, making it more prone to preignition in gasoline engines. Lower compression ratios or the use of anti-detonant additives may be necessary to prevent preignition when running on kerosene.
What modifications are required to run a car on kerosene?
To run a car on kerosene, modifications to the engine and fuel system may be necessary. This can include adjusting the compression ratio, using a different carburetor or fuel injection system, or installing a fuel heating system to aid in vaporization.
Are there any engines that are specifically designed to run on kerosene?
Yes, some small engines, such as those used in antique tractors, were designed to run on kerosene. These engines may require fewer modifications compared to modern car engines, as they were optimized for the specific characteristics of kerosene as a fuel.
Is running a car on kerosene recommended?
Converting a gasoline engine to run on kerosene should be approached with caution. It requires expertise and careful optimization to ensure proper performance and minimize potential risks. It is important to consult with professionals or experts in the field before attempting such modifications.
What are the potential risks of running a car on kerosene?
Running a car on kerosene without proper modifications and optimization can lead to engine damage, decreased efficiency, and potential safety hazards. The low octane rating of kerosene may result in preignition, and the higher flashpoint may require additional heat for vaporization, which can affect engine operation.
