First off, I know its not practical at all to run an engine on solely HHO made with a common hydrogen generator. But that?s besides the point, I need some help with the math here.

Can someone help me figure out what I did wrong with these calculations and what steps I need to add in?

A Geo Metro 1.0L engine running at 3200rpms (estimated at 65MPH) and at 60% throttle would require 67.8042CFM (cubic feet per minute) of the air fuel ratio.

(1000cc X 3200rpms) / 2.54 / 2.54 / 2.54 / 12 / 12 /12 = 113.0069cfm X 60% = 67.8042

We?ll assume that we are running a stoichiometric ratio at 14.7:1. That means there is a total of 15.7 parts (14.7 + 1 = 15.7). We?d need 63.4854 of air and 4.3187CFM of fuel.

(67.8042 / 15.7) X 14.7 = 63.4854CFM of air.

(67.8042 / 15.7) X 1 = 4.3187CFM of fuel.

An important key to remember is that Hydrogen Generators split the water, H2O. This means it not only generates hydrogen but also oxygen. There are 2 hydrogen molecules and 1 oxygen molecule, which gives us a total of 3 molecules. (2 + 1 = 3). So, in order to get 4.3187CFM of fuel (Hydrogen), we?ll need more than 4.3187CFM of HHO because part of it is oxygen. So we?d need 6.4781cfm of HHO to create 4.3187cfm of Hydrogen.

(4.3187cfm of HHO / 2) X 3 = 6.4781

With 6.4781cfm of HHO, we?d have?

(6.4781 / 3) X 2 = 4.3187cfm of Hydrogen

(6.4781 / 3) X 1 = 2.1594cfm of Oxygen

Therefore, in order for a 1.0L engine to run on HHO we?d need to inject 6.4761CFM of HHO and the engine would have to suck in 61.3260CFM of air.

However, when talking about engines and hydrogen generators, liters are more commonly used them CFM. So, we have to inject 183.3827 liters per minute of HHO to run an engine on pure HHO.

Using

www.ask.com 6.4761CFM is 183.3827 liters per minute.

Using

www.ask.com 61.3260CFM is 1736.5590 liters per minute.

I checked my math and it seems to work out, but I must be missing something. Because if I was trying to figure out how much gasoline an engine needed, wouldn?t I use the same method? But 183.3827 liters (48.4446 gallons) of fuel per minute is definitely not correct.

Can someone help me figure out what I did wrong with these calculations and what steps I need to add in?
