Abstract

Because domestic petroleum will continue to be an increasingly scarce commodity, and because expanded reliance on imported petroleum by the United States is not feasible, alternatives to petroleum must be found and deployed. To this end, methanol is being studied as an alternative fuel for four-cycle internal combustion engines.This work presents the results of an experimental and theoretical investigation into the use of methanol as a gasoline replacement.Three different methods of fuel preparation were analyzed, Dissociated Methanol, Prevaporized Methanol, and Late Vaporized Methanol.The results indicated that both Dissociated and Late Vaporized Methanol produced an approximate 6% increase in efficiency over Prevaporized Methanol.The measured engine data indicated, however, that insufficient waste heat would be available to dissociate the methanol for a Dissociated Methanol engine at low to medium loads creating an inherent limitation on the Dissociated Methanol engine. No such inherent limitation exists in the Late Vaporized Methanol engine.
