Why Kerosene is the Preferred Fuel for Airplanes
Discover why planes rely on kerosene instead of diesel for optimal performance and efficiency in high-altitude flying.
138 views
Planes use kerosene instead of diesel because kerosene has a lower freezing point, making it more suitable for high-altitude flights where temperatures are extremely low. Additionally, kerosene has a higher energy density, providing better fuel efficiency and range for aircraft. Its lower viscosity at cold temperatures also ensures smoother engine performance. Ultimately, kerosene's properties make it a more reliable and efficient choice for aviation needs.
FAQs & Answers
- What are the main advantages of kerosene over diesel for aviation? The main advantages of kerosene over diesel for aviation include a lower freezing point, higher energy density, and lower viscosity at cold temperatures, which collectively contribute to better fuel efficiency and reliable engine performance at high altitudes.
- Can diesel be used in aircraft engines? While diesel can be used in some specialized aircraft engines, it is generally not suitable for commercial aviation due to its higher freezing point and viscosity compared to kerosene, which are detrimental at high altitudes.
- What is the freezing point of kerosene compared to diesel? Kerosene has a lower freezing point than diesel, which typically allows it to remain in liquid form at the extreme temperatures encountered during high-altitude flight.
- How does the energy density of kerosene impact flight efficiency? The higher energy density of kerosene means it can provide more energy per unit volume than diesel, which enhances the overall range and efficiency of flights.
