Methyl tertiary-butyl ether (MTBE), which shows promise as an octane improver, has been introduced commercially in the US after successful commercialization in Italy and Germany. Comparisons are made of the fuel properties, single-cylinder engine performance, and road octane readings between gasoline and MTBE-gasoline blends. The study concludes that the compatibility of MTBE with gasoline will improve the road performance of unleaded gasolines. A leaner-engine operation was noted as a result of the blending and is attributed to changes in fuel stoichiometry and energy content. More extensive driveability, fuel economy, and emission control testing is recommended. 18 references. (DCK)
