Cylinder Head Porting and Power Production

Air is made up of 79% Nitrogen and 21% Oxygen. The Oxygen component is what you use, the Nitrogen component does not burn.

Fuel is made up Hydrogen and Carbon aka hydrocarbons. The first stage of the burn is Hydrogen. Then the question becomes whether or not you utilize the carbon component of the fuel.

I'm not sure if we are saying the same thing or not. Yes the O2 is an oxidizer but other than heating up and causing the Nitrogen to expand it gets far more credit than it deserves I feel. I understand you can't have one without the other of course. Yes all of the energy content comes from the fuel but it is the Nitrogen that actually does all of the heavy lifting. J.Rob
