Aviation fuel?

[scumdog]

.... your ignition is too far advanced, compression is too high etc.......

Kinda sums up the motor in my hot-rod truck - hence why avgas seems to make it run better (less pinking, smoother idle)

[marty]

...also the main reason why avgas is VERY good at burnung exhaust valves.
Aero engines have sodium filled valve stems to cool the valves (ones running a high bmep).
I wouldn't even think about exposing my sem fiddy's titanium exhaust valves to avgas

actually your engine will run quite happily on avgas - just a little expensive! It's the EDP and Aux pumps that will have issues - the 1900 can run on avgas all day, but the pumps can only go 10 hrs.

Ummm, you do realise he was taking the pi$$ right??
Actually a Diesel will run okay on Jet A1 okay for quite a while....

I know someone who did over 200000kms in a Mazda 323 diesel - all of it on Jet-A, with no additives at all. He commuted 200km a day in it, often at 0300am with the accelerator pegged to the floor at a max 145km/h.

The gearbox ended up grenading, but the engine was still mint.

If I wanted lead build up everywhere.
I don't. That's why it gets fed 95 or 98 octane motor spirit

Jet fuel is high quality kero. It would make great diesel fuel espcially in artic conditions.

Hi quality Kero?
Well, i would actually say a similer cut to Kero with a heap of other stuff added to it so it can be used in aviation. Not high quality at all...

When we were under training we had to learn about 9 properties of F34 (Jet A1 with a Fuel System Icing Inhabitor).
After reading the list you got the impression that you can't even burn the stuff!

In reality you need a bit of heat to get the stuff to ignite. You can put a match out in it quite easily.

Oh, it's cheaper than Kero.... Imagine going into Bunnings and getting 200000 litres of Kero to fill your 747

Yup, you could conceivably run the average turbine engine on diesel too, maybe even get some performance gain, but it will run way hotter and probably die in a short time..

Correct:
10 Hours between Hot End overhauls on the Viper, as opposed to 2500 hrs....

PT-6s run okay on diesel... provided it's not the high sulphur shit we get in NZ

I ran my ST-X Navara on kero a lot of the time - it would do about 80km less per tank on JetA than it would on straight diesel. It was cheap (<10c/l) so it didn't really matter

Yeah I wouldn't really go there unless I had to - it was more a factual statement than an actual

[wickle]

Another point, if a station is selling Avgas straight to Joe Public and actally letting customers fill vehicles with it, they will eventually get screwed. It is illegal to run Avgas in any street vehicle on a public road.

most stations that sell Avgas/racefuel get you sign a disclaimer that you will not use the fuel in a vechile that is going on public roads, I think the fine is quite high if caught,

Yeah right on, I remember one of the instructors at woodbourne talking about the "wasp" choppers that the navy used to operate ? Said they ran them on diesel when they had to but servicing time was cut down to a fraction of what it normally was..

You're right... Memory wasn't all destroyed in the bar

The Wasp was Auth'd to run on almost anything, including AvCat (The Ships fuel).... Just servicing times were compromised.

In actual fact, any Gas Turbine will run on anything, it is just that sometimes the Fuel is actually used for other things on the engine than just burning.
For example running servos in the fuel system....

Righto, lets see how far away from running AvGas in your bike we can make this thread

Jet engines and diesel engines will run on almost anything that has a calorific value, the swedish got a diesel engine to run on cream just because of the amount of fat in it.
The main difference between kero and diesel, as far as running in your truck is concerned, is that kero has a much lower lubricating ability and will wreck the fuel pump. If you add engine oil to kero, say 20:1, you virtually get diesel and the oil lubricates the pump.
Running a jet engine on diesel means everything will get lagged in soot, but it won't harm it.
