Aircraft Engine uses diesel?

[Edward Snowcone]

shouldnt (and didnt it) use avgas?

I guess avgas will be used for turbines later.

Avgas would be more correct for piston based engines. Diesel would actually be fairly appropriate for turbine engines.
In the Airforce (RNoAF) they use a mixture called D30, which was 70% Kerosene and 30% Diesel, or the other way around. It's been almost 20 years...

Aircraft engines should use AvGas, and if they dont its probably a bug.

aircraft use high grade diesel. I'm a flight mechanic on airplanes. We use the EXACT same fuel to run all our ramp vehicles as we do for our airplanes. Also, i'm not firmiliar with AVGAS. I have fueled my airplane all over the world and have never heard of airplanes using a different fuel. There ARE variations to the diesel (im only firmiliar with their military and nato names) such as F-34, F-44, or JP-5, JP-8 but the differences are minor. Subtle changes to additives.

AVGAS is used in general aviation aircraft engines. Diesel isn't typically used in piston aircraft engines because it requires a heavier engine to contain the compression required to ignite it. Turbine engines could burn anything I think, but are typically fed kerosene-based Jet fuels like Jet-A or JP fuels.

BROKEASAJOKE: You maybe do run all of your ramp vehicles on the same fuel as the aircraft. HOWEVER, that fuel IS NOT DIESEL! Diesel will burn in a jet turbine engine, however the freeze point of diesel is far too poor to be used in aircraft and would turn to jelly. You are simply running your diesel engined ramp vehicles on the kerosene that you would be using to fuel your jet turbine aircraft engines. Kerosene will run in most diesel engines just fine, and in some countries, where weather is too cold for diesel, they use kersosene all year round. As LORDJEKYL wrote: most jet turbine fuels are kerosene based. Piston engined aircraft are mostly AVGAS which petrol based just with a higher octane. 100 Octane for regular naturally aspirated engines and 130 Octane for supercharged or turbocharged engines, rather than most garage forecourt 87 or 93 octane that you would stick in your car. In which case, if your aircraft are piston engined and non-turbo, you could even be running them on regular 87 or 93 PETROL which a lot of cesna owners do. However, I would worry if you didn't know the difference between petrol and diesel vehicles even by sound at least??!
