Gasoline vapors are more flammable/explosive than gasoline in it's liquid form. So wouldn't it make sense to vaporize gasoline before it reaches the engine? I ask this because there's a guy in Florida claiming to get over 400 mpg on his Geo by vaporizing gasoline. Is this possible or is it just a myth?

I understand what carburators and fuel injectors do, but what if you heated up the gasoline before it got to the cylinders?

Pure what comes out the rear end of a bull. That was the job of the old carbureators, to vaporize the fuel before feeding it int the cylinder. They switched to fuel injectors because they vaporize and meter the fuel more efficiently. The best gas mileage will be obtained when the engine is runnung as "lean" as possible. In other words, when the fuel to air ratio has as little fuel and as much air as it can get without burning holes through the tops of the pistons. Too rich and left over gas trickles out the exhaust. Too lean and you burn up the engine. Guarantee you he'd burn holes through every piston long before he got it lean enough to obtain even 100mpg.

The gasoline when ignited in the engine is in its vapor form. The injectors atomize the fuel spray, the heat and pressure from the engine metal and the compression stroke take care of the rest.
