Av Gas

[turbo-EA]

tex, why can`t turbine juice be used in an internal combustion engine? and avgas not be used in turbines?

[killemaul]

I think I can answer this one..... jet fuel(kero) is very slow burning and hot burning by memory. so for use in cars that need the energy then and there at hi RPM it is shit! Tex am i right? or am i right.. am i right!!!!?????

While I can't quote specifics about combustion temps, basically if you had to compare it to something used in the automotive world, AVTUR (kerosene, remember) would be *similar* to diesel in its characteristics. I'm pretty sure that in emergency situations, gas turbine engines can even be run on diesel, though I'd imagine the maintenance guys would be pissed, as it probably means the engine would need to be rebuilt or something. :p

Sounds about right killermaul, kerosene is also fairly slow-burning, when used in a turbine engine, you don't want something that burns really rapidly, as you wouldn't be able to keep the flame alight in the engine.

Bear in mind I'm *not* an expert on the subject, but have been involved with aircraft enough to know what goes in what type of motor, and why, in broad terms at least.

so let me get this straight for 2 RON points you are going to risk a big fine and loss of many points when you could spend less money and add boost to 98pulp?
Waste of money too unless you change state of tune. AV gas is not well suited to small bore quick burn engines either as most aircraft engines are large bore low rev constant open throttle devices...plenty of literature out there on racefuel vs avgas

You can use kero/Avtur/metho/anythingthatwillburn in a jet engine and it'll chug away quite happily indeed.
It's standard procedure for some smaller turbine engines to use Avgas to clean them out a little.
We could use it on the old Citation I used to fly, but we were limited to only 25,000' and a maximum total of 70 hours between engine changes.

Now that you mention it, I'm pretty sure I've read of this being done with helos...

i remember hearing at willowbank when the two U.S. jet cars where out they could run on diesel (with LOTS of white smoke when they do the afterburner pops),kero and jet fuel.thought it sounded pretty cool! taking into account the cost of the alternatives i`d think diesel would be the go.

Is it legal to run cars on m/ethanol on the street? I've seen, well smelt, a number of tough V8s driving around running this sort of fuel.

Thats not entirely correct unless your refering to the heavy fuel used in large turbine engines (AVTUR). Normal avgas runs very well in small 4 and 2-stroke engines. I can get small knocking at 1bar using 98ron and avgas has no knocking at all at 1.2bar. I personally think its magic fuel and worth it for competition use and much better than having octane additives as the HC blend is much more consistant. But RON means nothing in the scheme of things its the MON that matters.

rhspecr the information came from a chemical engineer for ELF and was confirmed on the other forum by two race engineers. I do not have the tech background to judge the merits of all the aspects of the discussion, but testing showed that current BP 100 and elf race fuels superior.
Personally I would just not risk it on the street for the benefits...plus the cost PULP is expensive enough!
