You want to convert food to fuel? Fuel.economy is reduced as stoichiometric AFR requires more alcohol.
A number of years ago Detroit Diesel.had an experimental.engine program to run city bus engines on methanol. Medicine Hat, Alberta had 2 methanol plants shut down. They got involved to test them. Alcohol has such a high latent heat of vapourization that when the about double methanol was injected, the compressed air was cooled so much it would not ignite. The heads were cast differently to retain heat and had provision for the glow plugs from the 5.7L auto diesel. There was a glow plug controller with LEDs that flashed at idle. When fired up it ran like a top fuel engine. When they came back from doing a route they ran good for a couple of minutes until they cooled a bit, then back to dragster idle. These engines on diesel fuel in city buses usually lasted 350,000.to 400,000 miles. At first they only got 50,000 on methanol. The methanol was washing down the cylinder walls. A number of fuel additives were tried and got engine life up to 100,000 miles. When converted back to run on diesel, the fuel systems had to be primed to start. That is when the head design to retain heat was found out. The heat would boil the fuel in the fuel manifold on shutdown. Diesel heads fixed that. Interesting experiment to be part of.
