Have been looking at the Pogue carburetor concept for fun recently, the "200mpg" engine of the '70's that used a pre-heater for gasoline to vaporize it to a gas, and allowing 02 to bond with it before allowing it to enter the cylinder. The idea is that you get 100% combustion efficiency, better power and emissions. Certainly during WW2 Gasoline engines were converted to run on wood gas and coal gas vapors...

There are a number of youtube videos out there of various attempts, perhaps successful, to get engines to run in this manner, and they are interesting enough in their own right, but this one is of particular interest:

Its not the best video, as the host simply shows a number of old engines and doesn't actually run any of them. He does however mention one of these engines, perhaps a 3 cylinder conversion of a Buick engine, was at one time installed into a Delorean. Over 15 years on these forums and its the first I have ever heard about that... Someone must have seen this thing and be able to give a report or two about how well it worked, or didn't. To be honest, if anyone could get something like this to work - it would probably be a Delorean owner. Hey Bill, you still out there?

Here is a more generic video where someone SEEMS to get this concept to work. So... enlighten me?
