How Jet Fuel Compares to Diesel: Key Differences Explained

Discover the key differences between jet fuel and diesel, including their composition and engine compatibility.

72 views

Jet fuel and diesel are both hydrocarbon fuels, but they are formulated for different purposes. Jet fuel usually contains kerojet-A (kerosene) that has a lower freezing point and does not have the same lubricating properties as diesel, which is essential for engines. Although similar, they are not interchangeable without proper modifications to the engine.

FAQs & Answers

  1. Can jet fuel be used in a diesel engine? No, jet fuel cannot be used in a diesel engine without modifications due to differences in lubrication and freezing points.
  2. What are the main differences between jet fuel and diesel? Jet fuel has a lower freezing point and different lubricating properties compared to diesel, making them suitable for distinct engines.
  3. Is jet fuel more expensive than diesel? Typically, jet fuel can be more expensive than diesel due to refining processes and aviation-related costs.
  4. What is kerojet-A? Kerojet-A is a type of kerosene used in jet fuel that provides better performance at high altitudes and lower temperatures.
