Research on the Influence of Hydrogen and Carbon Monoxide on Methane HCCI Combustion

抄録

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.
