I don't know about the 200mpg carb but an adiabatic engine is a crude name for a sterling engine. It and the ericson engine are the only two engines that come very close to the perfect carnot cycle. Unfortunately the sterling engine is very unpractical in vehicles because of not being able to properly throttle the engine. It's an external combustion engine, and after adding heat to it it takes a good 5 to 10 seconds before it reacts and settles into a steady state larger load output. Imagine the worst turbo lag x10. If you are interested in messing with one, you can buy these little working models of sterling engines. Just place something to burn under the heater side, light it up, spin the crank and it just goes and goes until you put out the burning element.
