and while the potential energy in Jet-A is slightly less than gasoline on both a mass and volume basis,
|Quoting SEPilot (Reply 4):|
Do you have figures? I had always thought that kerosene had more energy per unit of volume than gasoline. I used to have an old John Deere two cylinder all fuel tractor; it would burn either gas or kerosene; on kerosene it used less than half as much fuel per hour as gasoline to do the same work. And I was also under the impression that jets have so much more range than piston engines did because the fuel contained more energy.
|Quoting Rwessel (Reply 5):|
But it's important to remember than diesel engines typically manage to extract a fair chuck more useful energy from the fuel (35-40% vs. 25-30%). That's largely due to the much higher compression ratios.

Maybe the engine is more efficient working as a Diesel?
