Hi Sean -

Note weasel word - "approx"...  :)

In practice a "how big is a fish" question, because of variables like wheth=
er
fuel vapor is really a vapor, or a suspension of small droplets, mixing, an=
d
so on. Best power in carburetted engines usually ran around 13:1.

Reference "The Internal Combustion Engine In Theory & Practice", Vol. 1,
2nd Edition, revised, C.F. Taylor, pp. 46-47.

Worth reading, btw, and undoubtedly in Cornell's fine library.



The range of explosive mixtures (for kaboom purposes) is generally
considered to be between 10-15:1.

Anyway
