What the hell does diesel have to with this?

Thanks for confirming you have no idea what you're talking about. Diesels use compression ignition. Gasoline engines have a spark plug.

I'm done talking to you now, have a nice day!

Damn the Diesel have a low eq octane number. This is an example. An illustration. Ok got it now?

I will remind you that you slipped the purpose of our conversation from : "the octane does not rate what E you can output in a compression work" to "detonation and deflag."

But as always simplistic argument and quick assumption on individual are the way to go with the 100octaner. One more in a long series.

Do you really think that I don't know the diff btw Diesel and gasoline? If such salute and have a good day back to your black and white world.*

What i was showing you is that with higher grade you hve higher energy in the same volume of the cylinder hence more heat hence (what I was expecting you'd understand by yourself) more wear since the eng is not designed for that amount.

We are not talking about a 2L 90Hp car but 1000HP with primitive engine technology with low compression ratio (a lot more fuel flow).

Thx for loosing my time too.

*I hve to admit that writing this my blood was boiling up to its flash point. Sry for being rude

Back on topic....

"British Performance Reduction Methods for Modern Aircraft", D Cameron - A. & AEE Report No. Res/170, 1942.

Is cited by papers on googlescholar. Spitfireperformance.com has many references to test data from later Spitfire marks being normalised using this method to some standard atmosphere.

I've looked on "Web of Knowledge" and some other places but have not been able to get a copy.

I suspect that, since Cameron felt it necessary to write a paper in 1942 to standardise the methods, other variants were probably used before. I'll continue trying to find it.

take care that perf predictions were not accurate during the war as they didn't hve the knowledge that became available after the war*. I think there is something with the Glauert correcting factor that you might be interested to investigate.

Search the PROCAT for:

ha ha yeah. diesel is a lot different than 100LL

humm Gympy put that hand ON the table

?? I dunno just from a fuel aspect.

my .02 is that we just give ALL the planes the best Octane available have 100 Octane Me-109's, Spits etc. etc.

then nobody can complain

even on the CoD forum ? :rolleyes:
