Is that doable? You mentioned a normal The correct stoichiometric ratio for air:fuel is 14.7:1. I have not heard about the Japanese engineers doing anything crazy like 24:1. In fact, generally the a/f rato must be run a bit rich due to less-than-ideal mixing. > -- what does O 2 stand > for == is O oxygen== what about 2. I was sick during > chemistry classes. O stands for the element oxygen, and the 2 means there are two molocules bonded together. Oxygen has 6 valence electrons, and it likes to travel in pairs so that it can steal valence electrons from each other. ===== --Mike Pittinaro Christmas is over now So I'm changing my haiku Thank you, David Brown __________________________________________________ Do You Yahoo!?
