This report reviews the various approaches which can be employed to facilitate the utilization of alcohols - methanol and ethanol - in light duty diesel engines. The characteristic problems and the relative advantages of each approach are discussed. It is concluded that successful application to an engine of any of the available systems would require considerable development efforts. The choice of which system to employ is likely to be most heavily influenced by the proportion of alcohol substitution which is required and the resulting engine first cost penalty which is deemed to be acceptable. Alcohol utilization by more or less conventional spark ignited engines appears to be far less problematical than conversion of diesel engines.
