• To investigate the process of spark ignition in a methane-air mixture, numerical analysis with elementary reactions and ion-molecule reactions has been performed. For this investigation, two chemical reaction schemes are employed : One, defined as Scheme A, contains 32 reaction steps. The other, defined as Scheme B, contains 81 reaction steps. It is concluded that minimum ignition energy of Scheme B is a little higher than that of Scheme A, because the formation of ion-molecules needs much heat absorption. Comparing with experimental data, it is said that Scheme B is better simulation of real spark ignition. It is also concluded that a pathway for the production of CHO^+ and H3O^+ during discharge period is important for spark ignition.
