So your running an engine on gasoline vapor..............(insert crickets chirping).............? I hate to break it to you but the internal combustion engine already runs on fuel vapor. They don't run so well on liquid fuel (this would be a condition known as a flooded engine). With fuel injection the fuel is sprayed in a fine mist (atomized) onto the intake valve. When the valve is hot it will help vaporize the fuel.
I guess I'm not quite sure what you think you discovered?
