Bill, what do you think of cooling the exhaust gas to the
point where the water and hydrocarbons condense out to a liquid
and then separate the unburned  gasoline from the water
and recycle the gasoline to the fuel tank? The water can then be
fed back and used to help cool the exhaust gas upstream from the
condenser.

Seems like there is not much heat in the exhaust and a lot of
waste chemical energy when a car is going only 80 km/hr.

There is very little unburned gasoline in the exhaust of any reasonably
tuned engine. The chemical energy in your chart, is mostly partially
oxidized hydrocarbons, (CO, aldehydes, etc. ) that are going to be hard to
recover, certainly cannot recover them by condensation -- the heat exchanger
would be huge, and most of them are gases or low boiling point compounds.

The catalytic converter is getting rid of *trace* amounts of hydrocarbons by
oxidizing them, if you had very much, it would overheat and/or coke up with
carbon deposits (i.e. running super rich is not good for the converter).

Thanks Bill. What exactly the waste chemicals energies were in the exhaust
was a question in the back of my mind. I incorrectly assumed, for
the moment, they were usable gasoline. I suppose you could say
the combustion chamber works as a cracking system.
