Nitrogen enriched fuel?
Okay, so I am getting gas today at a Shell station and notice signs up about nitrogen enriched gas.
Hmm, I think back to college chemistry and my training in medical gas piping. Med gas piping the nitrogen is used to purge air so inside of pipe doesn't oxidize during brazing. Wondering how an inert gas(nonflamable) is going to enrich gasoline. Is there a chemical reaction when the gas burns that makes the nitrogen useful? Just wondering? Any input? Lars
