In recent years several studies have been done in the field of laminar flame speed. One of the important characteristics of the combustion is the laminar flame speed. In this study, the effects of CO2 and N2 on the laminar flame speed of natural gas and gasoline fuel mixture have been investigated. Schlieren method has been used in this study. Experiments were carried out at pressure of 1 bar and 363 k in constant volume chamber. The mass fraction of CO2 and N2 varied from 0% to 12%.The result shows laminar burning velocity and the adiabatic flame temperature decrease with the adding CO2 and N2 Specific heat capacity of CO2 more than N2, for this reason the laminar burning velocity of N2 more than CO2. Also the result shows Addition of CO2 and N2 does not cause much change in stability.
