Well, you are just avoiding the facts here:

No, You need to read the handbook.

In fact, give Lycoming customer service a call. They will be glad to help you out.

P=nRT/V from perfect gazes theo.

The pressure output from the comp of a gaz depend of the volume V and the Temp T achieved before detonation*

The less volume at the end, the more P.

The temp T at which the gas will detonate under pressure is the leading factor here.

The derivative energy (work) that someone can output of a compression work (isentropic**): dW=-dP/dV wich as you see is a function of the octane number for a specified eng design

AS the Tot energy of a gas equate the sum of it's internal molecular energy that is in the theo of perfect gazes is the sum of the work done on that gas and the total output heat achievable (see the first law of thermodynamics (here : http://en.wikipedia.org/wiki/First_l...thermodynamics)

Then I think I am right

- sry for the boring refreshing cursus - didn't do that pretentiously.

Well now we are good to open another new thread

*n is a ref numbers in moles (or molecules per volume at a specified state) and R is a cte defining the ratio btw the products

**means here without any modification of the gazes's product state (which is never fully achievable in virtue of the second principle of thermodynamics)
