The ignition delay times behind shock waves in CH4–, and C2H6–O2–Ar systems containing CF3Br were measured for a range of temperatures between 1400 and 2100 K and pressures between 1.5 and 3.5×105Pa. These measurements indicated that CF3Br promotes the ignition of CH4but inhibits the ignition of C2H6. Although the inhibition effect for C2H6increases with increasing CF3Br concentration and decreasing temperature, the promotion effect in CH4was independent of both the CF3Br concentration and the temperature in this experiment. We calculated the induction times for conditions similar to the experiments using a model which included 49 elementary reactions related to CF3Br. Calculations using this model gave induction times that were in good agreement with the experiments. The calculated values, however, depended on several effective reactions among the 49 reactions. |
