A/F ratio and fuel volume

[Jason_Leone at amat.com]

<<Does anyone have a formula for find required cc's of fuel for a given
cc's of air for stoichometric(sp?) mixture. Any useable volume units
will be sufficient. Thanks>>

Damon,

This seems to simple, perhaps I'm missing something here. Stoichiometric
(Lambda) is 14.7:1 air/fuel ratio. So, 1 CC of fuel to 14.7 CCs of air is
stoichiometric, in theory. Just divide the air volume (of any unit) by 14.7 (of
the same unit)to calculate the fuel volume needed to equal Lambda. For example,
if you had a total volume of 45 CCs in the cylinder head...then 45/14.7= 3.06
CCs of fuel required for Lambda. Granted, this is just an estimate. There are a
lot of other factors, such as temp, chamber geometry, injector
type/placement/spray pattern, system pressure, ignition timing, and a few
others. But, to answer your simple volume question...just divide by 14.7 and
correct for any unit you use (metric or SAE). Good luck.
