AirVenture Product Minute: Austro Engines Make OSH Debut

[N21X]

I had been told once that one of the main differences between Jet-A and diesel is that they add paraffin to diesel to help with lubrication. The paraffin can cause a clogged mister in a turbine engine.

Has anyone else heard this?

yep, you're perfecly right. Other differences are the addition of anti freezing elements that allow use of Jet A1 down to -50°C, temperature existing at approx 30000ft. But as an engineer, i believe that the freezing problem can be solved using specific carburant heating circuit : as diesel is a non explosive fluid, its management and temperature keeping of the fuel tanks should only raise a weight problem in future designed aircrafts.

Diesel is common in the states for cars, but not yet so much on airports. Fortunately, diesel engines also burn jet fuel, with no problems.
