In this research, the influence on natural gas combustion of H2 and CO was investigated by numerical calculations with elementary reactions. The investigation was carried out using the following procedures: 1. To research basic oxidation characteristics of CH4/H2/CO mixed fuel, parametric calculations for initial temperature were carried out. 2. For investigation of the effect of H2 and CO on CH4 combustion, the calculations with H2 and CO initial mole fraction variation was carried out. As a result, it was clarified that the oxidation temperature of CO was higher than that of CH4 and H2, the increase of H2 initial fraction has the effect to advance CH4 ignition timing, and increase of the CO fraction, under the condition that only CO was added, has the opposite effect of H2 addition.
