bad idea
fuel is about 1 15th of the Mass of the air fuel mixture prior to combustion assuming the engine runs at or close to stoich or Lambda of 1 ,
heating the air will have a much greater effect
and
heating the air has been experimented with a whole lot in the pages of this forum

so you can read up on the success or lack thereof of current and past experimentation regarding WAI

you can learn from the pain of others , if you have your wits about you and make your own informed choice

those who will not learn from the mistakes of history
are doomed to repeat them
