In this study, the effects of various oxygenates for gasoline on exhaust emissions and fuel economy in MPI and GDi vehicles were investigated. Various oxygenates such as MTBE, TAME, ETBE, Bio-ethanol were selected. Oxygenate blend fuels that oxygenate were added in suboctane have about 2.3 wt % of oxygen content. FTP-75 mode and HWFET mode, which are widely used in Republic of Korea and the US to test fuel economy, were applied to investigate exhaust emissions from the test vehicles. Gaseous emissions such as CO, NMHC and NOx did not show any significant correlation with oxygenates, although a slight difference between oxygenate blend fuels and suboctane as a base fuel was observed. The combined fuel economy of a blend fuel having MTBE increased 0.3 % in an MPI vehicle and 1.3 % in a GDi vehicle, but that of other fuels decreased. In particular, the combined fuel economy of a blend fuel with bio-ethanol decreased 2.7 % in an MPI vehicle and 1.6 % in a GDi vehicle. The particle number concentration of oxygenate blend fuels was less than that of suboctane, but the difference between oxygenate blend fuels was slight in FTP-75 mode. In HWFET mode, the particle number concentration has a very similar tendency in MPI and GDi vehicles. When compared with each of the oxygenate blend fuels, the particle number concentration of a TAME blend fuel was highest while that of bio-ethanol was lowest.
