As a subject matter expert in the field of energy and fuels, I've spent considerable time analyzing and understanding the various types of fuels used in different applications. Let's delve into the differences between gasoline and jet fuel, two distinct types of fuels designed for different engines and operating under unique conditions.
Gasoline is primarily used in internal combustion engines found in automobiles and light-duty vehicles. It is a petroleum-derived liquid that consists of a mixture of hydrocarbons ranging from C4 to C12. Gasoline is designed to be volatile and ignite easily at lower temperatures, which is why it is ideal for spark-ignition engines. The volatility of gasoline allows it to be vaporized in the carburetor or fuel injector and mixed with air to form a combustible mixture that ignites upon reaching the spark plug.
One of the key characteristics of gasoline is its octane rating, which is a measure of its resistance to knocking or pinging during combustion. A higher octane rating indicates that the fuel can withstand higher compression ratios without detonating prematurely. This is crucial for high-performance engines that operate at higher compression ratios to maximize power output.
On the other hand, jet fuel, also known as aviation turbine fuel, is designed for use in gas turbine engines, which are found in aircraft. Jet fuel is quite similar to kerosene and is typically a larger hydrocarbon mixture, ranging from C9 to C16. Unlike gasoline, jet fuel operates under high-pressure conditions and does not rely on spark ignition. Instead, it uses a continuous combustion process where the fuel is sprayed into a combustion chamber and ignited by the high temperature of the compressed air.
The octane rating of jet fuel is significantly lower than that of gasoline because it is not subjected to the same detonation concerns as gasoline. The refining process for jet fuel is less extensive compared to gasoline, which often results in a higher sulfur content. High sulfur content can lead to increased emissions of sulfur oxides, which are a concern for air quality and environmental regulations.
Another important aspect of jet fuel is its energy density and cold weather performance. Jet fuel must have a high energy density to provide the necessary power for long flights and must also be able to flow and ignite at low temperatures, which can be a challenge at high altitudes.
In terms of processing, jet fuel is often one of the least-refined products from a refinery unless it is specifically processed through a hydrocracker, which can remove sulfur and other impurities, resulting in a cleaner-burning fuel.
In conclusion, while both gasoline and jet fuel are derived from crude oil, they are formulated and processed differently to meet the specific requirements of their respective engines. Gasoline is tailored for spark-ignition engines with a focus on volatility and octane rating, whereas jet fuel is optimized for continuous combustion in high-pressure environments and must maintain performance across a wide range of temperatures.

It is very similar to kerosene. It has a much LOWER octane rating that gasoline. It tends to have a much higher sulfur content than gasoline. Jet fuel is one of the least-processed and least-refined products from a refinery, unless it is hydrocracker kerosene.
