A method and system is disclosed for supplying an internal combustion engine with a plurality of fuels wherein a first fuel source 10 which is conventional lead-free gasoline is provided and a second source of fuel 12 which consists of from 180 to 190 proof ethanol is provided as a second fuel source. The fuels are maintained separately and are fed to the intake manifold 18 of the internal combustion engines separately and simultaneously via injection valves 34 and 36. Upon injection to the heated intake manifold, the fuels are vaporized and mixed in the vapor phase prior to combustion in the combustion chambers 32. An electric coil 46 is provided for heating the alcohol fuel and enhancing vaporization. The method also includes injecting water vapor into the combustion chamber with the gasoline and alcohol in the ratio of 0.5 to 2.5 percent and of including either Diethanolaminebenzoate, Dimethylbenzalkoniumchloride, Dicyclohexylaminenitrite, and/or Mercaptobenzothiazole as corrosion inhibitors.
