A thick burning zone including unburned and burned gas is observed in turbulent premixed flames. In this study, the burning rate and the ion current in the burning zone were investigated in propane-air turbulent flames in a spark-ignition engine cylinder and a constant-volume combustion chamber. The main results are as follows: (1) in propagating turbulent flame, the rate at which mass is burned is not equal to the rate of mass entrainment to the flame front; (2) the ratio of the combustion rate per unit area of turbulent flame front to that of laminar flame, Z=(M_<bT>/A_T)/(M_<bL>/A_L), is a reasonable expression of the effect of turbulence on the combustion of propagating flame; (3) the ion-current signal has multiple peaks in turbulent flame. The average number of ion current peaks increases with the enlargement of burning zone and the value of Z.
