Comparison of computed and measured auto-ignition delay times versus 1000/T (K). Symbols: shock tube data [1] ○: 13 bar ▵: 40 bar; Solid Lines: detailed mechanism by Zhao et al. [10]; short dashed lines: 28-species reduced chemistry (this work); long dot-dashed lines: 26-species skeletal mechanism by Yao et al. [14, 15].
