I would like to publish a manual that would describe the process of optimizing a D or B series motor to burn Ethanol or grain alchohol. The properties of Ethyl Alcohol would make it an ideal candidate for a high compresion motor. The trade off is, of corse, more fuel is required. I already have a working, small scale distillery that has the ability to produce enough fuel to meet my transportation requirements. Currently, my ethanol is used in the production of biodiesel to run a generator, and power another vehichle. however we are not going to produce biodiesel any more because the generator has been replaced by new equipment and the home-brew process is very time-consuming. This leaves me with the need for a new use of the Ethanol. Naturally, I chose my Del Slow. For my ethanol: The feedstock comes from a variety of sources listed from worst to best: 1. Cellulose (newspaper, sawdust, corn husk, etc) 2. Starches: Corn, Potatoes, Wheat, etc. 3. Sugar crops: sugar beets, sugar cane, sweet sorghum, ripe fruits. For those of us who live in an urban place, the first option may be more economic. Although I am able to obtain "expired" produce from small groceries and markets in my area and use this to make my mash. Knowledge on making alcohol is easily available and the process is beyond the scope of this short post. Most people could produce a usable fuel in their back yard with minimal equipment. I'm interested in gaining any knowledge or experience from those who have used ethanol, methanol, or other high octane fuels in a modified, high compression application of our honda motors. I know there is a wealth of this kind of experience on this forum. I look forward to our discussion.
