Numerical study on auto-ignition characteristics of hydrogen-enriched methane under engine-relevant conditions

[Display omitted] •Chemical kinetic mechanism was used to study the ignition process of CH4/H2 mixture.•Influence mechanisms of hydrogen addition on the auto-ignition for CH4 were revealed.•Reactions (R1, R2, R3) become important with rising H2 fraction at high temperature.•Hydrogen addition weakens...
