Diesel Airbus Crashes, Carbon Buildup?
You guys think you have it bad when a diesel car gets carbon buildup. Wait until you fly a new diesel Airbus...

Not as dumb as it sounds, isn't Diesel fuel very similar to jet fuel? One would think that this has probably happened before without anyone ever noticing.

When I work as a AME a few years ago, we worked for a medium size airline company that had to pay another company to get rid of its old kerosene when we were purging the tanks. Lol instead of paying them, they asked their employees who had diesel car to take it. We were bringing 45 gallons on a trailer to bring it back home for our Tdi's Lol that was very smart for us and them until they got caught by Transport Canada and were shut off permanently !! |

Diesel is a heavier fuel, with a bit more energy density then jet fuel. Jet fuel contains 12 carbon long hidrocarbon molecules while diesel carries 16 carbon long ones. While diesel is a fuel for compression ignition engines, jet fuel can be used on compression or spark ignited engines. Jet fuel on diesel engines will work but performance will suffer, while on gasoline engines it can improve output/fuel economy

I meant kerosene Not jet fuel ! Thanks for the correction. The jet fuel was used in our race car (gasoline car)at the drag strip while the kerosene was given to diesel guys in the hangars. |

PR, JP-5 (Nato F-44) is closest to diesel, but still a partially wide-cut kerosene, not exactly the same as ASTM 975-spec D-2 Diesel, per se. JP-5 is used primarily on board naval vessels for fuelling aircraft and helicopters, and has a higher flashpoint than JP-4 (Jet B) which is a fully wide-cut kerosene. JP-8 (Nato F-34 or civvie Jet A/A-1) or JP-8 +100 (F-37) are narrow-cut kerosenes that are a balance between the stability and safety of a distillate fuel like diesel and a partial aromatic-content shorter-chain hydrocarbon. JP-8 is close enough to diesel that it can be used in multi-fuel capable vehicles, particularly military diesel-powered vehicles. JP-8 does not, however, have the same lubricity as diesel, even ULSD, so if used in diesel vehicles, requires additional additives to ensure no damage to the engine's fuel injection system result.
Having flown turbine-powered aircraft using diesel as an alternate fuel, I would be very surprised if the aircraft crashed due to being fuelled with D-2 diesel...turbofans/turboshafts run reasonably well, albeit a bit smokey, on diesel. Regards D.

Well, my mostly joking implication was that regularly using diesel in a jet could result in carbon buildup similar that found in automobile engines and thereby possibly cause a much worse incident than we will ever see in our cars.

Our vehicles are special: they need JP7.

So you are saying that I am buying this: http://en.wikipedia.org/wiki/JP-7 for $4.00 a gallon? Wow, what a deal.
