Abstract : This report describes the results of a study into the behavior of several alternate fuels that are under consideration for use in general aviation aircraft engines. The study consisted of a literature search and engine tests using a dynamometer. The literature search identified material compatibility problems and possible solutions to these problems. For the engine tests, a number of gasoline/alcohol blends were prepared using both ethanol and methanol in varying concentrations and the vapor lock behavior was identified. Neat alcohols and methyl-tertiary-butyl ether were also used in the engine and special operational conditions and problems were identified.
