The calcu lation re sult s indicat e t hat t he ignition delay i s reduced wit h t he increa se of oct ane number w hile it i s rai sed wit h t he increa se of oct ane number . The co mp re ssion ratio , airf uel equivalence ratio and inlet air t emp era t ure have great effect s on t he ignition time of above t hree kinds of f uel . The inlet air p re ssure ha s t he rela tively le ss influence on t he ignitio n delay of t he high oct ane number f uel , but ha s an obviou s eff ect on t he ig nitio n delay of t he high oct ane number f uel . 摘要 : 以二甲醚 、甲烷/ 丙烷混和物 、异辛烷/ 正庚烷混合物作为燃料 , 模拟研究了燃料成
