Show from GRI -Mech 1.2 for application to more practical computer modeling requirements. The reduced mechanisms of 22, 19, and 9 species show good performance compared to the full detailed chemical model. An initial optimized mechanism for NO production and rebuming chemistry was added to GRI-Mech 1.2 to form GRI-Mech 2.1 ACKNOWLEDGEMENTS This work was supported by the Basic Research Group of the Gas Research Institute.
