Ideas for fuel names

These are just a couple of suggestions for the two fuels I recently came up with...

For the fuel that uses nitrogen from the atmosphere...
A.I.R fuel, for the A.I.R Engine (A.I.R- Air/Atmospheric Infused/Intake Reaction)

For i-fuel...
I.N.Fuel for the I.N.F Engine (I.N.F- Inter-Nitrogenous Fuel)
