Lawrence, D C; Niemczak, D J

This paper presents the objectives and results of a vehicle emission test program conducted by the U.S. EPA in July 1980. The program was designed to investigate the effects of using various gasohol blends on vehicle evaporative and exhaust emissions. Particular emphasis was directed towards a blended gasohol whose volatility characteristics were adjusted to match as closely as possible those of a baseline gasoline. Two vehicles received triplicate tests on each of four fuels. The analysis also included a gas chromatograph characterization of the SHED vapors for ethanol concentrations and a comparison of carbon balance fuel economy versus volumetric fuel economy.
