expansion ratio

[al1]

I'm looking for some help in getting the basic values used in estimating the expansion ratio of regular gasoline i.e. how many times will 1 cubic inch of air/fuel expand when combusted? Also if 1 cubic inch of air/fuel is combusted at 1 atmosphere what would be the estimated pressure be if it is still contanied in the 1 cubic inch?
Thank you

AL1: As a first approximation you can use the perfect gas law of

PV=nRT

and the balanced chemical equation of the combustion.

The balanced equation will give you the amount of the material in the process as well as the ehat liberated.
