“…The physical effect of dilution gases of different components on the IDTs of methane was also investigated. The effect of NO x and SO 2 on methane oxide-air mixture igni-tion was studied by Kazangas et al 14 The results showed that the addition of SO 2 has no obvious effect on IDTs and the effect of NO X on ignition is weakened with the increase of equivalence ratio under medium pressures. Meanwhile, the effect of NO 2 on IDT is more obvious than that of NO.…”

In this study, the effects of CO2/H2O dilution on the ignition delay time (IDT) of methane under different conditions were studied by the method of sensitivity analysis, mole fraction analysis and reaction path analysis. The predictions of six published kinetic models were first compared with experimental data from the literature; the kinetics of the model judged best were then analyzed in greater detail to investigate coupling effects of different ratios of CO2/H2O dilution, temperature, pressure, and equivalence ratios on the IDT of methane. Through this research, it was found that under high temperature conditions (1700–2000 K), the IDT increases with CO2/H2O ratios increasing. At the equivalence ratio of 2.0 and low to medium temperatures (1000–1700 K), the diluent gas at the ratio of CO2/H2O = 0.4/0.6 has the maximum suppression effect on methane ignition, and the inhibitory effect of diluted gas in the IDT can be enhanced by 4.9% compared with other cases. Through the path analysis, it was found that the reaction path under the condition of CO2/H2O = 0.4/0.6 is changed into the O radicals generation reactions and CH3 consuming Reactions (R155, R106, and R158) comparing with the condition of CO2/H2O = 0.8/0.2. By providing insight into the factors affecting the IDT of methane under a wide variety of conditions, the present study extends our understanding of methane combustion and can be used to guide the development of a combined application of EGR and in‐cylinder water injection.
