Did you have a look at Smokey's drawings and facts on his working
engine in a car, before you posted this?

I believe that the thermodynamics involved don't fit the problem.
Evaproating the fuel as it goes into the engin won't provide sufficient
cooling to do the job.

Snicker. You got that right! Gasoline has a specifc heat of 0.50
BTU/lb/deg F and a vaporization point of about 350 deg F. Heating the gas
from 70 deg to 350 deg could absorb 140 BTU/lb from the exhaust out of a
total of 18,000 BTU/lb that will be burned.

Darn it, I missed another free lunch.
