    초록 This research is to decide the possibility of using RM50 without any modification of engine by calculating the experiment data. Comparing of heat release rate, the difference among each fuel decreased according to the increase of the engine speed, and the maximum heat release rate is high in the order of RM50, gasoline and LPG fuel, and the timing to reach the maximum heat release rate precede in the same order. This order corresponds to the order of burning speed. RM50 has the highest turbulent burning speed, and the difference among each fuel decreases according to the increase of engine speed. The curve of turbulent intensity showed similar tendency to the curve of turbulent burning speed and as the engine speed increase, the difference of maximum turbulent intensity for each fuel increased. This is caused from the increment of turbulent component following the increment of the engine speed. RM50 has relatively high burning speed, short quenching length, high temperature in cylinder and, so that it might increase NO emission, but owing to chemical reaction dynamics, it decrease NO emission. Therefore, in predictation of NO emission using RM50, it is needed to consider not only the temperature in cylinder by low heating value, but also combustion characteristics including burning speed. As the result of combustion noise analysis of CPL, generally, CPL is higher in the order of RM50, gasoline and LPG which corresponding to the order of burning speed.
