Methyl tertiary butyl ether (MTBE) is believed one of the most famous oxygenated compounds for gasoline to improve octane quality but its largescale application is hindered due to the high water solubility causing adverse effects to environment. Herein, ethyl butyrate (EB) and methyl butyrate (MB), which can be made via esterification of relevant alcohols and have much lower water solubility than MTBE, were investigated as alternative oxygenates comparing to MTBE. The exhaust emissions, fuel economy and engine performance of 10 volume percent of each EB, MB and MTBE blended gasoline (EB10, MB10 and MTBE10, respectively) were evaluated on a gasoline engine. All properties for EB10 and MB10 are similar with those of MTBE10. However, EB10 and MB10 showed slightly higher CO emissions and slightly lower fuel economy than those of MTBE10, because the heating values of EB and MB are lower than that of MTBE. From engine dynamometer test, every test fuel showed similar power and torque result. This study shows that ethyl butyrate with the lowest water solubility among the three compounds can be a promising option for an alternative oxygenate.
