These five units comprise a course intended to prepare and train students to conduct alcohol fuel utilization seminars in spark ignition and diesel engines. Introductory materials include objectives and a list of instructor requirements. The first four units cover these topics: ethanol as an alternative fuel (technical and economic advantages, properties of ethanol and gasoline), engine coversions (three main methods of utilizing alcohol in a spark ignition engine), engine conversion through carburetor modifications and ignition timing adjustments, and alcohol fuel in a diesel engine (six stages of diesel combustion, diesel and alcohol test results). Unit 5 lists references and available additional information and provides a glossary of alcohol-related and automotive terms. (YLB)
