초록	In order to investigate the characteristics of gas flow during flame propagation process, the flow fields of unburned gas are qualitatively and quantitatively measured by using Nd-Yag laser PIV system. The main results are as follows ; After ignition, it is shown that the unburned gas in front of the flame spreads out in the direction of radius by compression effect of flame expansion. Although the flow pattern for fuel-air equivalence ratio are qualitatively similar to each other, the maximum expansion velocity of unburned gas is measured at the 1.1 in equivalence ratio. By comparing above results with those obtained by the flame velocity and burning velocity, it is also found that they have the difference of about 10%.
