    초록 In this experimental research, the characteristics of the transient mode in SI engine were studied to compare with pure gasoline and the fuels of RM50 (reformulated fuel) for performance and exhaust emissions without reconstruction of engine systems. In the condition of WOT (wide open throttle), =1 (air acess ratio), torque does not show a big difference between gasoline and RM50, however, RM50 shows a higher BSFC (brake specific fuel consumption) and thermal efficiency relatively. RM50 has a wider range of combustion limitation, which is one of the methanol's characteristics. RM50 has relatively a low cycle by cycle variation, which is used to determine the driving state. It is determined that fuel stability is better and cycle by cycle variation varies within 10%, therefore, driving characteristics is relatively good. In all conditions, RM50 have lower exhaust eniissions of CO, HC NOx than gasoline. HC is not severely different according to using fuels because it is not affected by fuel components. As a whole, RM50 shows a lower NOx emission because of combustion temperature and chemical reaction dynamics. RM50 has less incomplete combustion and it can be observed by the result of CO emission characteristics. RM50 shows 2-3dB less noise characteristics than gasoline in the condition of WOT=1, however, RM50's noise characteristics is 0.5-2dB higher at part load condition. This is caused by a faster combustion speed of RM50 at part load, resulting an abrupt increase in pressure. This reason can be supposed acceding to the driving condition that to be noise is altered. Results of the experiments of rubber fusion and metal corrosion are very similler relatively and it increase the utility possibility of RM5
