    It has been known that oxygenates increase octane number of gasolines. There are MTBE and bio-ethanol known as typical oxygenates and a lot of increasing interests have been given to the researches on ETBE to alternate these oxygenates. In this study, the performance and emissions of fine particle number with changing ETBE contents and spark ignition timing in single cylinder engines have been studied. There were trends that oxygen contents and RON increased with increasing ETBE contents of gasolines. And the ignition delay became longer and the burning velocity was reduced with increasing oxygen contents. Net caloric value and RON of gasoline has affected BMEP and BSFC for various ignition timings. Knocking intensity sharply increased with advancing ignition timing, but the difference in the knocking intensity of high RON fuels was relatively low. And fine particle number emissions rapidly increased with advancing ignition timing.
